Early 1960s Maple Syrup Industry Films – Paul Smith’s College Library

By Matthew M. Thomas

The archives of Paul Smith’s College has digitized and shared online a series of six films, originally shot in 16 mm color, that show various scenes of maple sugaring in the early 1960s.

When I contacted the archivists at Paul Smith’s to ask about the background on the films it was shared that very little was known. The films more or less appeared at the archives with no supporting information. It was not apparent who made the films, but in viewing, it was clear that the majority of the footage was made in New York state which suggested that possibly someone from the maple research program  at Cornell University, or possibly maple equipment manufacturer Bob Lamb out of Liverpool, NY had made the films.

I strongly suspected the films were shot by Bob Lamb considering he never personally appeared in any of the footage and the heavy emphasis on documenting only Lamb’s Naturalflow tubing with no examples of the other competing tubing product at the time.

My suspicions were confirmed when after a little sleuthing and digging in my research files from the Fred Laing folders of the maple research archives at the University of Vermont Special Collection turned up a notice from May 15, 1961 that was sent by Bob Lamb to the vendors that were selling his Naturalflow plastic tubing.  In this notice Lamb writes:

A small group of us have been running 16 M.M. Colored movie cameras this spring over quite a wide spread area. We have tried to make the film a general “MAPLE FILM,” specializing in showing hundreds of miles of tubing and working right.

The film covers tubing, from taking tubing into the woods, tapping the trees, installing tubing, an (sic) disassembling, as well as washed and stored. The entire operation from start to finish. This portion is part of the Lloyd Sipple story. This part of the film is a wonderful way to show a prospect that has a great doubt as to what to do with tubing after he gets it. It will help others that want to improve their ways of using tubing.

None of the footage in the six films in the Paul Smith’s archives appears to be a single finished film that has been edited and prepared for distribution. Rather, it appears instead to be many minutes of raw footage, oftentimes showing the same general scene over and over. Also, as raw footage, some of the scenes appear to be underexposed and can be rather dark at times. it should also be pointed out that there is no audio with these digital films.

Announcement on page 11 of the November 1962 of the Maple Syrup Digest from Bob Lamb informing readers about the production and availability of a series of maple syrup films.

Subsequent research has located an advertisement placed by Bob Lamb in the November 1962 Maple Syrup Digest where he makes it known that he has filmed and prepared new films in 1962 in addition to his 1961 film and that these are available free, by request, for showing at maple meetings. He also notes the run time of the films, which are shorter than the Paul Smith’s footage, suggesting what he was offering were edited “finished” films and the Paul Smith’s films are the raw footage. Lamb also noted that none of these films had sound added at that time.

Based on the date and information in Lamb’s 1961 mailed out notice and 1962 Maple Syrup Digest ad, as well as the known date of the group photo at the Cooperstown meeting of the National Maple Syrup Council (1963), the footage in the films can be said to range from 1961-1963.   Other elements and details in the footage, such as the packaging featured at the Reynolds Sugar Bush sales room, are consistent with this date range.

The six films feature various scenes and locations, mostly in New York but also in Ohio and Wisconsin. The bulk of the footage was shot at the sugarbush and sugar house of Lloyd Sipple in Bainbridge, New York. As mentioned in the quote from Bob Lamb’s notice, the focus of the footage is presenting Lamb’s Natural Flow plastic tubing in use so there are many minutes devoted to tapping and installing the tubing, checking tubing lines, and demonstrating tubing removal, dismantling and cleaning.

Because this was in the era when tubing was still new and evolving technology, it was recommended at the time that tubing should not be left hanging in the sugarbush and instead should be removed and meticulously cleaned and stored at the end of the season before being reinstalled the following winter. Likewise, it was the belief and recommendation of Bob Lamb at the time that his tubing should be laid across the ground or surface of the snow and not strung taunt at waist or chest height.

A number of individuals notable in the history of the maple industry and maple research are recognizable in the footage. These include sugarmaker and editor of Maple Syrup Digest, Lloyd Sipple of Bainbridge, NY; Dr. C.O. Willits of the USDA Eastern Regional Research Laboratory in Philadelphia, PA; Dr. Fred Winch of Cornell University; and Dr. James Marvin of the University of Vermont. There are also specific recognizable sugarbushes that appear in the footage, some brief, and some for many minutes. These include the Sipple’s Pure Maple Products in Bainbridge, NY ;  Reynolds Sugar Bush in Aniwa, WI; Harold Tyler’s Maple Farm near Worchester, NY; Ray Norlin’s Central Evaporator Plant in Ogema, WI; Taylor Farm Sugar Camp in Stamford, NY; Keim’s Kamp Maple Products in West Salisbury, PA; and the Toque Rouge Sugar Camp in Quebec.

   The latter half of the film was shot at two sugarhouses in Wisconsin. There is about one minute of exterior and interior scenes show Ray Norlin’s brand new Central Evaporator Plant in Ogema, Wisconsin, which was built in 1962. Norlin’s was one of the first purpose built Central Evaporator Plants that made maple syrup almost exclusively from sap purchased from local sap gatherers rather than from sap gathered in a sugarbush owned or operated by the sugarmaker.

A substantial portion of this footage features the Reynolds Sugar Bush plant at Aniwa, Wisconsin during the boiling season.

There are scenes of sap being delivered and received by Juan Reynolds, both in large tanks drawn by a team of horses and in milk cans brought to the plant in the back seat of a car. Other scenes at the busy plant show an interior sales room with a enormous variety of syrup tins, bottles, as well as many shapes and designs of ceramic and plastic containers.

Other scenes show Adin Reynolds operating a syrup boiling tank as well as Lynn Reynolds describing one of the Reynolds’ large underground concrete syrup tanks located in their sugarbush.

Title – Maple Production Cut 2  – Time: 32:43

Comments: Based on the style of architecture of the houses and cabins (notably flared eaves on the roof forms) the film was shot at a few sugarbushes and sugarhouses in Quebec including a visit to a sugarbush producing under the name of Toque Rouge (Red Cap) maple syrup.

Footage of Lamb tubing installations in Quebec at this time show it being widely adopted through the maple syrup world and Quebec sugarbushes were using the same layout and tubing design as in sugarbushes in the United States. One closeup of the text printed on the tubing reads Naturalflow – Montcalm, Quebec” showing the location where Lamb tubing for Quebec markets was being manufactured.

There are similar views of, installation, inspection of tubing lines that have already been hung and the trees tapped, as well as footage of breakdown and removal of the taps and plastic tubing using various designs for winding the tubing on reels or spools.  Two sugarhouses in the film show large oil fired evaporators, fairly sophisticated for the early 1960s.

Mountain Meadow Farms: Somerset County’s Modern Central Evaporator Plant

By Matthew M. Thomas

Mountain Meadow Farms was a gigantic maple syrup operation and game farm that operated in Somerset County, Pennsylvania in the 1960s and 1970s. Somerset County is known for its prominence and history as a maple syrup producing area in Pennsylvania. What made Mountain Meadow Farms unique, both in general and in Somerset County in particular, was that rather than being a small family sugaring operation that grew over time, Mountain Meadow Farms was created from scratch as a new operation on a scale not previously seen with the most modern technology and design available at the time.

1974 advertisement for Mountain Meadow Farms from The Republic out of Meyersdale, PA.

The Farms began in 1964 when Blaine “Bud” Walters and his wife Geneva purchased an existing game farm in the hills of Somerset County about two miles north of the village of New Baltimore, Pennsylvania. The Walters were the owners of the successful Walters Tire Service in the town of Somerset. Started in 1941, Walters Tire Service focused on manufacturing, retreading, and selling large size tires for road building equipment and servicing large trucks used in the Pennsylvania coal industry.

Mountain Meadow Farms had its own custom-designed lithographed metal syrup cans. A popular can among syrup can collectors.

According to one account, it was the Walters farm manger Gerald Grasser, who came up with the idea of making maple syrup. As the Walters’ son Jimmy Walters tells it, “Bud never did anything small. When they bought the farm it already had pheasants. There were two pens of pheasants when they bought it and they added turkeys and cattle. There were lots of maple trees so it made sense to tap those.” In addition to pheasants and turkeys, there were chuckers too. Cattle was usually around 300 head, but at one point with calves and heifers, it got up to close to 1000 head which required a lot of feed and work with Walters installing big Harvestore silos and automated feeding machines.

When Walters settled on the idea of starting a maple operation around 1963, over the next two years he promptly did everything he could to learn about the maple syrup business. For example, in 1965 he attended Maple Industry Conference in Philadelphia and when it became known just how large of an operation he was planning, he was put in touch with Adin Reynolds of Reynolds Sugar Bush, in Aniwa, Wisconsin, at that time the largest maple sugaring operation in the world. In addition to being able to offer Walters practical advice on setting up and running an operation of this size, the Reynolds Sugar Bush was an equipment dealer for the Vermont Evaporator Company and in the fall of 1965 made the sale to Walters of three 6 x 20’ oil fired evaporators along with all the requisite piping, tanks, and finishing equipment, as well as tapping supplies, plastic tubing and bags for collecting sap from around 20,000 trees. A brand new, 50 x 110 foot, state of the art sugar house was built at a cost of $75,000, complete with finishing area, candy making room, and sales area.

In all likelihood, the Reynolds encouraged Walters to focus not only on tapping his many thousands of trees, but also to initiate a plan to get local farmers and families to gather and sell sap to him, similar to how the Reynolds operated their many Central Evaporator Plants in Wisconsin. The Walters made purchasing sap a big part of their operation right from the start. In the spring of 1966 in their first year of operation, they tapped 17,000 of their own trees and bought sap from 8,000 trees tapped by others in the vicinity. In the following years Walters increased his sap buying efforts bringing in sap from 25,000 trees paying 5 cents a gallon for delivered sap and 4 cents per gallon for sap that was picked up. As Jimmy Walters recalled, the farm had a mini fleet of tank trucks to pick up and haul sap along with four 10,000 gallon open tanks for sap storage. The farm was also able to enlist the efforts of a number of local 4-H clubs and scout groups to taps trees and gather maple sap, a valuable fundraiser for their organizations.

The Walters were new to the maple business, but they quickly made it known that they manufactured a good product, taking home a number of awards for their maple candy and confections in the judging at the county maple festivals. Despite their newness to the maple industry, Bud Walters’ growing role as an industry leader was recognized and in 1969 he was elected to the Board of Directors of the Somerset County Maple Syrup Producers. In 1970 Bud Walters was crowned county Maple King based on the performance of Mountain Meadow Farms maple products at the festival. Rightly so, Bud acknowledged that that award was only possible because of his wife’s efforts and it really should go to her. However, there were certainly some maple producers from the area who were suspicious and resentful of his approach and rapid success.

The farm sold most of its products through direct sales and mail order sales and through accounts with a number of restaurants and a few retail locations in Pittsburgh. Mail order sales piggy backed on their sale of game birds with a special package of a smoked pheasant and a fresh pheasant and maple syrup. In addition to making syrup and candy, and encouraging the use of creative and attractive packaging, Geneva Walters was a strong proponent of expanding the range of products that could be made and marketed with maple syrup. Related to that, Jimmy Walters shared that his mother was so influential in introducing new maple products, such as a maple syrup based salad dressing, that the Somerset County maple festival was forced to add more categories for judging beyond the traditional syrup, sugar, and candy. Jimmy added that this was one of his parents most important contributions, expanding the range of maple products being made and opening folks’ eyes in the county to other ways to sell and make maple syrup.

As a large operation focused on efficiency and cutting-edge technology, it was chosen in 1969 as the test site of the USDA’s Eastern Utilization Research Lab experimental Reverse Osmosis (R.O.) system. C.O. Willits and his colleagues from USDA’s Philadelphia Lab had developed a portable R.O. unit for testing in real-world sugaring operations. The previous season it was tested at the Sipple sugarbush in Bainbridge, NY but it was decided that the amount of sap available from the Sipple sugarbush for running through the R.O. was insufficient to really measure the R.O.’s performance. Instead, the lab researchers needed a larger operation like Bud Walters’ to really test how well it processed sap. The USDA test R.O. was operated at Mountain Meadow Farms again the following season, contributing valuable information to the USDA labs development and improvement of reverse osmosis as a viable technology for the maple syrup industry.

Making syrup from 40,000 to 45,000 taps in the 1960s and 1970s positioned Mountain Meadow Farms as arguably the second largest maple operation in the world, second only to the Reynolds Sugar Bush in Wisconsin.  By 1974 the farm was advertising itself to be “The Largest and Most Modern Central Evaporating Plant in the World!” and was clearly helping push and pull the maple industry to a new level of technological sophistication. But it did come with costs. According to Jimmy Walters, the farms had fairly high overhead with payroll to meet and little actual profit coming in. Many of the business ventures the Walters were involved with, including Mountain Meadow Farms were operating on loans and credit and at that time interest rates were relatively high at around 20-21%.  The last season of the Mountain Meadow Farms maple syrup making operation was the spring of 1977. When the costs of operation became too great Bud Walters decided to sell and attempted to keep the sugaring operation together and sell it as a package to an interested buyer. Unfortunately, at that time, the scale of the operation was simply too large for any potentially interested buyers.  In May 1978 the farming and sugaring equipment of the farm were sold at auction and the Mountain Meadow Farms ceased to operate. Bud and Geneva Walters passed the tire business to their son Jimmy in 1978 and enjoyed retirement. Bud passed away in 1990 and Geneva in 1995.

Reynolds Sugar Bush: Putting Wisconsin on the Maple Syrup Map

By Matthew M. Thomas

By one measure of mid-century popular culture, greatness or notoriety was achieved when one appeared on one of the television shows, What’s My Line, I’ve Got a Secret, or To Tell The Truth. On these shows celebrity judges attempted to guess the identity of a notable contestant placed among a group of imposters. In 1965, Adin Reynolds of Aniwa, Wisconsin had the honor of appearing on To Tell The Truth by virtue of his family business, Reynolds Sugar Bush, being the largest maple syrup making operation in the world. Reynolds’s appearance on television was surprising to many since Wisconsin is not among the first states that come to mind when thinking about maple syrup production.[1]

Since the Reynolds family arrived in Wisconsin from New York State in 1845, making maple sugar and syrup had always been one of many components of the family’s diversified subsistence and commercial activities. However, like many of their Shawano County neighbors, it was logging, sawmill operations, and dairy farming, not maple syrup production, that formed the core of the family business during their first 70 years in the state.[2]

Over the course of the first half of the twentieth century maple syrup production in the United States was in a state of gradual decline. While this decline was most pronounced in New England and New York, the core of the maple producing region, it was also true of Wisconsin maple syrup production. Maple syrup and maple sugar making has been a spring time activity in the seasonal rural economy of Wisconsin starting with the resident Native American population to early Euro-American settlers, and on to the dairy and those harvesting forest-products in the far north.[3]

In the years following World War II, maple syrup making reached an all-time low in the United States. At the same time, rural America was witnessing important shifts in attitudes and demographics along with the introduction of new agricultural technology and business models. For those that were able to recognize the opportunities and willing to take the risks, such change presented opportunities previously not possible. It was from such a place and a willingness to think and act independently that Reynolds Sugar Bush grew from making syrup as a small seasonal side pursuit to their sawmill and dairy operation, to a year-round, factory-scale business, becoming the industry leader far from the maple syrup heartland of the northeastern United States and adjacent Quebec.

The ability for a syrup operation to grow so large was possible by building the right processing facilities and infrastructure, having a market to sell the syrup, and literally tapping into the trees of their neighbors. But growth did not happen overnight. The Reynolds family had been tapping a few thousand trees in the mid-1940s but in 1947, things began to change when they built a new sugarhouse near their farm house, adjacent to a paved county road and alongside the Chicago and Northwestern Railroad line. They also began a partnership that year as the midwestern dealer and distributor of maple syrup making equipment for the Vermont Evaporator Company. With the syrup plant now alongside the road and making syrup on two large evaporators, they began buying sap from around 4,000 of their neighbors’ taps, augmenting more than 6,000 taps on their own land.[4]

To provide some stability and supplement their farm and forest products business, years earlier Adin Reynolds had taken work as a part-time mail carrier, later becoming the postmaster of Aniwa in 1948. His new emphasis on maple syrup making and equipment sales were paying off, and in 1951 Adin retired from the post office and began focusing on maple full-time. Up until the late 1940s there were no maple equipment dealers in Wisconsin or adjacent Minnesota and maple producers had to buy their evaporators and other large supplies from dealers in Ohio, New York, or New England. There was a clear opportunity and eager group of customers in the Midwest.[5] Around this same time, Reynolds also entered the syrup buying business, purchasing bulk syrup from other producers to be combined and resold to larger processors, syrup blenders, and bottlers. In 1948 the J.M. Abraham Company of Bellefontaine, Ohio contracted with Reynolds to provide the Ohio syrup packing company with all the syrup Reynolds Sugar Bush was willing to spare from their own production and all the syrup Reynolds could acquire locally. Reynolds Sugar Bush began shipping truckloads of syrup to the Abraham Company, adding syrup buying and brokering to the growing portfolio of their maple syrup operation.[6]

Although Adin was founder and leader of Reynolds Sugar Bush, his two sons, Juan and Lynn, were graduating from high school and making their way in the world as adults. Both sons always had roles in the syrup business, but as young men they were able to take on greater responsibility. The early half of the 1950s saw Juan and Lynn temporarily pulled away from the family business with Korean War era service in the Army and Marines followed by college education. However, in the late 1950s both sons had returned to Aniwa and began working full-time in the now flourishing family maple business. As Lynn Reynolds later described it, in the late 1950s and 1960s Adin oversaw everything and “created the management, marketing, and financing; Juan managed the plant and the personnel; and Lynn was the public relations person, salesman for equipment, the syrup buyer, and managed the production plants.”[7]

Through the 1950s, Adin continued to expand Reynolds Sugar Bush syrup making operation, using his quiet charisma to convince farmers and woodlot owners around Shawano, Langlade, and Marathon Counties to tap their maple trees and sell their raw sap to Reynolds. Reynolds also began renting additional trees to augment the maples on their own 800 acres as well as buying sap from their neighbors. In 1949 Reynolds added a third large (6’ x 20’) evaporator, and by 1956, the Reynolds were making syrup from 25,000 of their own taps and buying sap from many thousands more. Another evaporator was added to the plant in 1958 and all four evaporators were converted from wood burning to oil burning. Adin Reynolds was said to have hated cutting a maple tree, comparing it to cutting off an arm, so the family never thinned their maple woods and burned waste slabs from a local sawmill prior to switching to oil.[8]

Processing sap gathered from many independently owned sugarbushes at one large boiling facility became known as the Central Evaporator Plant (CEP) model, and Reynolds Sugar Bush became leaders in perfecting and promoting the CEP.[9] The idea of only selling sap rather than taking on the whole task of making finished syrup was not invented by Reynolds, although he took it to another level. The Wisconsin Department of Agriculture had been promoting the idea and use of a central evaporation plant for maple syrup producers since the 1930s.[10] Locally in the 1930s and 1940s, a group called the Antigo Maple Syrup Producers Association, in which Adin Reynolds was an early leader, attempted to pool their efforts in processing sap and marketing maple, without much success.[11] For Wisconsinites, the CEP concept will look familiar, with its strong resemblance to the arrangement of local dairies, creameries, and milk cooperatives, where dozens of farmers sell or deliver their raw milk to a central processing facility. Like butterfat in milk, the value of and compensation for raw maple sap was based on its relative sugar content measured by a refractometer. Sap at 1.5% sugar might get three cents a gallon while sap at 6% sugar might earn six cents a gallon. As Juan Reynolds described it, “if they had a halfway decent season and a good sugar content, they could make at minimum a dollar a tap. One guy down the road had real sweet trees, he often averaged more than $2 a tap, that is more than a guy making maple syrup could do after you have invested in all the boiling equipment and marketed it.”[12] As with milk, sap from multiple sources is combined and handled by individuals with the technology, expertise, and market connections to turn their raw product into a packaged or processed item for sale and distribution. Combining and finishing the concentrated sap at a central location resulted in better quality and more uniform syrup than was often produced in smaller sugar houses and backyard boiling operations at that time.[13]

The countryside around the Aniwa plant is marked with dairy farms interspersed between stands of second growth sugar maples. Farm families had the two most important components for sap production – trees and available labor to tap and gather. Moreover, the months of March and April were the slow and muddy seasons for most farm families. People in the region were more than willing to tap their maple trees and sell their sap for cash. Juan Reynolds recalled that they had as many as 50-60 families from within a 20-mile radius selling sap to them, with most of the sap sellers tapping 500-800 trees.[14]

In 1959, the General Foods Corporation, the makers of Log Cabin Syrup, a blend of cane and maple syrup, contracted with Reynolds Sugar Bush to purchase 20,000 gallons of maple syrup. With scheduled deliveries of syrup from Reynolds’ Aniwa plant to General Foods’ Chicago bottling plant, Reynolds began serious entry into the syrup buying business. For General Foods, the Aniwa bottling plant was attractive because it was close enough to Chicago that Reynolds Sugar Bush could fill syrup orders quickly, if needed. This large of a syrup contract led Reynolds to start shipping syrup 4,000-gallons at a time via tanker truck. Wisconsin was not producing enough syrup to meet this need, so Reynolds began buying in the northeastern United States and Canada.

At its peak, the General Foods contract had Reynolds Sugar Bush shipping twenty-seven tanker loads (108,000 gallons) of syrup from Aniwa to Chicago. At that time in history, moving this volume of maple syrup out of a midwestern hub rather than New England or Quebec was a significant departure from how the maple industry had traditionally operated. Reynolds continued this contract with General Foods for 20 years until General Foods reduced the amount of maple syrup in their Log Cabin blend from 15% in 1959 to 2% by 1979. After the General Foods Corporation merged with Philip Morris in 1985 the previous contract arrangements were no longer honored and Reynolds Sugar Bush stopped supplying maple syrup to General Foods.[15]

With a growing contract for bulk syrup and more markets opening up, Reynolds Sugar Bush went through a period of expansion buying three equally large syrup making operations, beginning in 1960 with the purchase of George Klement’s Maple Orchard in nearby Polar, Wisconsin. For much of the 1950s, the Klement sugarhouse was also operating with a central evaporator plant model similar to Reynolds, buying sap from 50,000 taps and making syrup on four large 6’ x 20’ King brand evaporators. Other than converting the evaporators from wood fired to oil fired, the Reynolds changed little, continuing to work with Klement’s sap sellers and expanded the number of taps coming in to 65,000. In 1963 Reynolds acquired the CEP operation of Sidney Maas at Tilleda, Wisconsin where syrup was made on two 6’ x 16’ Vermont Evaporator Company boiling rigs.

Reynolds converted these from wood to oil and now all the CEPs under Reynolds control were fired with fuel oil. Since those plants relied on sap from the forests of sap providers, Reynolds did not have a ready supply of wood to burn.[16] The sap input was further increased at these plants and by 1964, Reynolds Sugar Bush was making syrup from sap coming in from over 100,000 taps.[17] The Reynolds’ confidence was clearly very high by this time, so much so that in 1961 Adin made the claim that the output from sugarbushes in the Aniwa area could outproduce any comparable area in Vermont![18]

The third maple syrup operation purchased by Reynolds Sugar Bush in the 1960s was in Kingsley, Michigan a short distance south of Traverse City. The Kingsley plant was opened in 1962 by General Foods who wanted to improve their access to maple syrup in an area relatively close to their Chicago bottling facility. Identifying Kingsley as an area with an abundance of maple trees and a local agricultural population that was largely without work in the spring months, General Foods leased an old pickle factory in town, engineered a sap boiling facility, installed four 6’ x 18’ oil fired, stainless steel evaporators, and operated it as a CEP from purchased sap. To assist and encourage the new sap producers to acquire tapping equipment, General Foods purchased large quantities of spiles and buckets to supplement the limited local supply and arranged a loan program with a local bank to finance producers.[19] By 1964, the Kingsley plant was making syrup from 65,000 taps.[20] Despite the size of the operation, its engineering was more complicated than it needed to be, and it was not running as smoothly as General Foods had envisioned. Having an existing relationship with Reynolds Sugar Bush and a familiarity with their other successful plants, in 1966 General Foods sold the plant to Reynolds Sugar Bush for next to nothing with the condition that all the syrup produced by the plant be sold to General Foods.[21] Reynolds operated the Kingsley plant as one of their satellite CEPs until the 1970s when interest in sap selling in the area fell to unmanageably low numbers and the plant was closed.[22]

Always looking for new ways to expand and promote the maple syrup industry and Reynolds Sugar Bush, Adin and family often hit the road in the summer, setting up sales and display booths at state fairs and festivals, and giving industry talks around the Midwest. Before the Wisconsin State Maple Syrup Producers’ Association (WMSPA) took over the responsibility in the 1990s, the Reynolds’ 100-foot by 40-foot display was the primary promotional booth for maple syrup at the Wisconsin State Fair.[23]

Reynolds even erected “The Sugar House” a roadside gift shop along Highway 45 targeted at tourist traffic travelling between Milwaukee and Chicago and the woods and lake country of northern Wisconsin.

 

 

One of Adin Reynolds most popular ideas for promoting the maple industry was an annual pancake breakfast and maple festival. Starting in 1950 with around 1000 visitors, every spring for over forty years, thousands of people descended on the Reynolds farm to celebrate the state’s maple syrup industry while enjoying a pancake breakfast, seeing what was new in maple syrup production, and finding out who made the state’s best maple syrup that year. In 1956 the WMSPA came on board to help and the festival grew to as many as 5000 attendees.[24]

Visitors were treated to maple syrup themed exhibits and speakers, live entertainment, and served an all you can eat pancake breakfast. Pancakes were cranked out on an assembly line with a pancake making machine designed by Adin called the “pancake depositor” that poured the batter for 24 pancakes at a time onto a griddle.[25] Maple producers entered their best syrup from the year for judging, competing for the honor of receiving the golden sap pail or golden sap spout. For 45 years the Wisconsin maple syrup festival continued to be held at Reynolds Sugar Bush through 1995 when it moved to Merrill and became the responsibility of the WMSPA.[26]

By the mid to late 1960s, all four plants operated by Reynolds Sugar Bush combined were processing over 1200 gallons of sap an hour on a dozen large evaporators from sap gathered from over 200,000 taps.[27] Adin had even earned a patent for his invention of a simple and economical hanger for disposable plastic sap bags, called the Sap Sak.[28] Without question, as emphasized with Adin’s 1965 television appearance on To Tell the Truth, Reynolds Sugar Bush had become the largest maple syrup making operation in the world.[29]

Although he was operating far from the maple syrup heartland, industry leaders in the North American Maple Syrup Council (NAMSC), recognizing the significance of Adin Reynolds’ influence and leadership, electing him Council Vice President in 1963 and President in 1965.[30]  Reynolds were strong proponents for research and bringing together the US and Canada sides of the industry in addressing maple issues important to both countries. Putting those views to action, Adin was instrumental in helping organize the International Maple Syrup Institute (IMSI), a group focused on developing markets for the maple industry. Adin Reynolds served as the IMSI’s second president from 1976 to 1977 and on its Board of Directors from 1980 to 1984.

Sons Juan Reynolds and Lynn Reynolds were as equally engaged as their father and continued his legacy of leadership with Juan an IMSI Board member from 1985 to 1997 and President in 1990 and Lynn an IMSI President from 1993 to 1995 and Executive Director from 1995 until his death in 1998. Lynn also served in a series of roles as NAMSC secretary, then Vice President and President from 1989 to 1993.[31] The IMSI established a Lynn Reynolds Memorial Leadership Award in 1999 to recognize the outstanding leadership of individuals in support of the international maple syrup industry.[32]

Adin retired from running Reynolds Sugar Bush in 1979 and turned over the leadership of the company to his son Juan. With retirement, Adin was given the highest honor by the maple syrup industry when he was chosen as the fifth inductee for the North American Maple Syrup Producers Hall of Fame. In 1982 he was one of five men recognized by the University of Wisconsin for his contribution to agriculture and quality of life in Wisconsin by the Dean of the College of Agriculture and Life Science at the University of Wisconsin-Madison.[33] Adin passed away in 1987 as the age of 82. Following in his father’s footsteps, Lynn Reynolds was inducted into the Maple Syrup Producers Hall of Fame in 1995 as the forty-second inductee.[34]

In the 1980s changing markets and an increased difficulty in finding seasonal labor pushed Reynolds Sugar Bush to scale back its sap buying and syrup production to making syrup at only one plant at their original location on the farm north of Aniwa.[35] Rapid growth in syrup production out of Quebec and lowering syrup prices became too difficult to compete with, leading to the loss of two of their biggest clients on the west coast. Eventually the losses became too great for Reynolds Sugar Bush and in 1991 they were forced to liquidate many of their assets, including their sugarbush, and resize and restructure the company as part of bankruptcy proceedings.[36] Around this time, two of their largest sap providers decided to make their own syrup leaving Reynolds Sugar Bush with too little sap coming in to effectively make syrup in a plant of their size. With reorganization and a limited sap supply, syrup production came to an end for Reynolds Sugar Bush, although equipment sales continued.

Operation of the company was put in the hands of Juan’s and Lynn’s children, the next generation of Reynolds, and Juan and Lynn Reynolds moved into retirement, although neither was especially idle when it came to helping with the family business or the involvement in industry associations. Lynn Reynolds carried on with his efforts as a representative and advocate for the industry in North America until his death in 1998 and Juan remained a hands-on advisor to the family business until his passing in 2008.[37]

With the Reynolds’ leadership and the foundation they helped lay, Wisconsin maple syrup producers went from being a minor contributor in the maple syrup industry to one of the leading states.[38] Reynolds own production numbers were undeniably significant, as was their influence as sap buyers, equipment sellers, and syrup brokers. Adin Reynolds succeeded in establishing a collaborative maple syrup production process based on the modern creamery that made sense in a dairy state like Wisconsin. Attempts at making syrup from purchased sap in the Northeastern United States and adjacent Canada have never been embraced the way it was in Wisconsin, possibly a result of the CEP production model being a significant departure and challenge to traditional ideas of syrup making. However, as one of the lead federal maple syrup researchers described it, “the current trend toward central evaporator plants has marked a new era in the maple industry.”[39] During the height of Reynolds Sugar Bush, Wisconsin moved from being the eighth ranked maple syrup producing state in 1930 to fifth in 1940 and 1950, to third in 1960, behind Vermont and New York where it more or less hovered for the next three decades.[40] Unfortunately for the Reynolds, the industry and markets shifted more rapidly than they were able to adjust and they could not maintain the same operation as they had in the past. Change came, as it always does, and it cost them but not before the Reynolds family and Reynolds Sugar Bush left their mark and put Wisconsin maple syrup making on the map.

Reynolds Sugarbush History Book Available Here

I am happy to share on this website a digital version of the late Lynn H. Reynolds’ book Reynolds, Maple and History: Fit for Kings. This colossal book shares the story of many generations of Reynolds family maple syrup making within the broader context of the history of maple industry in North America. Especially interesting in the book are the first hand memories and experiences of members of the Reynolds family from Wisconsin who were engaged at all levels and components of the maple industry for much of the 20th century. In particular, Adin Reynolds and his two sons Lynn and Juan Reynolds saw it all, from making a lot of maple syrup (they were the largest operation in the world for many years in the 1960s and 1970s), equipment sales, buying and selling syrup, to organizational leadership at the state, national, and international levels.

Originally published in 1998 with a limited number of copies printed, the book quickly sold out and went out of print. Having been asked on numerous occasions by folks interested in maple history where they might get a copy I decided to contact the Reynolds family and thankfully they were kind enough to grant me permission to create a PDF copy of the book and make it available to people for free on this website.

The book covers 578 pages, so be advised, the digital file is fairly large at 115 mb. In addition, I created an index for the maple syrup history topics covered in the book and have included it at the end of the PDF version. You can down load the book HERE or by clicking on the image of the book above.

Recommended Reads: Maple History from a Local or Regional Perspective

Every few years a new book comes out on the culture or history of maple sugaring and maple syrup many which are highlighted on this website. In addition to these new and easily found books are a number of classics that those interested in maple history may want to look for and add to their collections. Here are four such books written with a local or regional focus that were all published over ten years ago, some of which are now out of print.

From oldest to newest, first we have the book When the Sugar Bird Sings: The History of Maple Syrup in Lanark County by Claudia Smith. Published in 1996, this great little book features the history and stories of maple sugar and syrup making in and around Lanark County, Ontario. It is illustrated with numerous historic photos of Lanark County maple operations and boasts of Lanark County as the Maple Capital or Ontario. While out of print, this book can be found used online at such sources as www.abebooks.com and www.amazon.com.

Next up in the lineup is a massive 578-page tome from 1998 titled Reynolds, Maple and History: Fit For Kings by the late Lynn H. Reynolds from Aniwa, Wisconsin. This book, a labor of love for Lynn Reynolds that highlights the events and importance of the Reynolds family and their Reynolds Sugarbush, was privately published in a limited run of 450 copies by the Reynolds family, sadly only a few weeks following Lynn’s passing. In the 1960s and 1970s the Reynolds Sugarbush was the single largest maple syrup producing company in United States or Canada, making maple syrup from well over 125,000 taps. The three men of the company, father Adin Reynolds (1905-1987), and brothers Lynn H. Reynolds (1936-1998) and Juan L. Reynolds (1930-2008) were all prominent leaders in the maple industry during their heyday and both Adin and Lynn were inducted into the Maple Syrup Producers Hall of Fame.

Written from the memory and point of view of Lynn Reynolds, the book tells many histories in a side-by-side chronological fashion with the story of the Reynolds family presented in one font,  maple syrup industry history in another font, and general local, Wisconsin, US, and World history presented in a third font.  For the maple historian the book is chock full of names, dates and descriptions of events in the history of both the Wisconsin and North American maple industries. The Reynolds sections of the books recount the interesting growth of the Reynolds company as maple industry juggernaut despite of being located in north central Wisconsin, far from new England or Quebec.

Lynn Reynolds was not a shy man nor one to temper his opinions when they mattered to him, so unsurprisingly the book does suffer from a bit of Reynolds exceptionalism, but in all honesty, that is not without some degree of merit, since the Reynolds family was very influential and the Reynolds Sugarbush was pushing the scale of maple operations at that period in maple industry history. If you can find a copy of this book snatch it up immediately. I have used my copy so extensively for reference I even built my own index for easier use, available here. My copy has seen so much use (in spite of being purchased new) that it is coming apart at the binding, so maybe at some point in the future I will scan the whole book and seek permission from the Reynolds family to make it available here.

Third in this list is the book Maple Sugaring In New Hampshire by Barbara Mills Lassonde. Published in 2004 by Arcadia Publishing as part of their Images of America series, this book is still in print and available at the Arcadia Publishing website. Like all books in the Images of America series, Maple Sugaring in New Hampshire is a photo history book with hundreds of great images and accompanying captions tracing the history of maple production in New Hampshire from the colonial days up into the 21st century.

Lastly, is the very well researched book Spotza, Keelers, and Stirred Sugar: The Legacy of Maple Sugaring in Somerset County, Pennsylvania by Mark Ware. Released in 2006 by the Historical and Genealogical Society of Somerset County, this well illustrated book presents years of research on the methods, material culture, and economic history of sugaring in a small but very active corner of Pennsylvania. With his position as the Executive Director of the Somerset County Historical Center, Mark Ware has taken the time to look deeply into the records, family histories, and artifacts and antiques. That knowledge is shared both in this book and in the exhibit of reconstructed 1860s sugar camp at the Somerset Historical Center. This book can be purchased online from the Somerset Historical Center website.

The History of Paraformaldehyde Use in the Maple Syrup Industry

Like with seeded agricultural crops, maple syrup production, also a plant-based crop, faces the challenges mother nature and the natural environment throw at it.  The challenge has been finding safe and effective methods of overcoming the battle with microorganisms, like bacteria and fungi, that also want to enjoy the sap of a freshly tapped maple tree. Applying pesticides has been a solution in agriculture and food production for eons, and, for better or worse, the maple industry was not spared. Unbeknownst to many, since pesticide use is not allowed today, the previous century was witness to the maple industry working through its own history of finding, embracing, and ultimately abandoning, pesticides in the sugarbush.

In the early 1950s, research began for the development of an antimicrobial application that could be used to slow or eliminate the detrimental effects of microbial growth on sap quality and sap flow at the tap hole of the tree. Researchers at the USDA Northeast Lab, the University of Vermont, Michigan State, and MacDonald College in Ontario all confirmed that the slowing of sap flow, and in some cases stoppage, over the course of the tapping season was in part attributed to the growth of micro-organisms such as yeast and mold at the area of the taphole.  The tap hole was in effect a fresh wound in a tree that emitted sugar rich sap, a welcome environment for microbial growth.

Looking for a way to counteract this microbial growth, in 1956 under the direction and funding of C. O. Willits at the USDA’s eastern regional research laboratory, researchers responded with various approaches to tap hole sterilization and improved sanitation. The bulk of the research and development effort was carried out at Michigan State University by forestry professor and maple specialist Putnam Robbins and microbiologist Robert Costilow. Robbins and Costilow experimented with a variety of chemical treatments and methods, eventually settling on trioxymethylene, also known as paraformaldehyde.[1]

Robbins and Costilow found a small pill-like tablet with 250 milligrams of paraformaldehyde embedded in agar to be the simplest and most effect method to administer the chemical at the taphole. Sometimes called PF or PFA pellets, the pellet would be inserted in the fresh drilled tap hole prior to the insertion of the spile, and the agar would slowly dissolve over the course of the season.

Research by Robbins, Costilow and others examined how much PFA residue remained in maple syrup made from PFA treated sap holes.  They found that the overwhelming percent was less than 1 parts per million (ppm) and that 100% of syrup samples tested were less than 2 ppm. Robbins and Costilow began promoting the idea of use of the pellets in 1960 and submitted an application for approval for manufacturing and use to the Food and Drug Administration (FDA). Paraformaldehyde was registered with the EPA as a pesticide with approval to distribute for use as a disinfectant for bacterial plant pathogens and fungal diseases in maple tree tap holes and went into use for the 1962 maple sugaring season. Formal approval for use began when the tolerance levels were published on February 20, 1962 in the Federal Register under 21 CFR 121.1079. At some point oversight shifted to the EPA and it was moved in 1975 to 21 CFR 123.330 for regulation by the EPA. Based on Robbins and Costilow’ s research, tolerance level for PFA in maple syrup chosen by the FDA was set at not to contain in excess of 2 ppm of PFA. The decision to set the tolerance level at 2 ppm was somewhat controversial, since later studies found naturally occurring levels of PFA being higher than 2 ppm in completely untreated trees, and treated trees showing zero ppm.[2]

1967 advertisement from R. M. Lamb company promoting their sale of the Flomor brand paraformaldehyde tablet.

With PFA being approved for use by the maple industry, three manufacturers were registered to produce the pellets, all three of which were prominent sellers of maple equipment and supplies. Lamb Natural Flow, Inc. of Liverpool, NY made Flomor brand pellets, Sugar Bush Supply Company of Mason, MI made Ma-pel brand pellets, and Reynolds Sugar Bush of Aniwa, WI in conjunction with the Vicksburg Chemical Company of Newark, NJ made Sapflo pellets. A bottle of 500 pellets generally sold for $5.00 at that time.

As hoped, application of PFA pellets to fresh tapholes resulted in substantial increases in sap production over the course of the season with a 20% increase on average and as much as 50% increase in some cases. One pellet manufacturer and large-scale producer even went so far as to say the pellet was “probably the most significant profitability tool that has ever been developed for our industry.”[3]

1967 advertisement from Vicksburg Chemical Company and their partner Reynolds Sugarbush promoting the Sapflo brand paraformaldehyde tablet along with Fermaban and Myverol, their other chemical preservatives for maple syrup and maple confections.

Manufacturers and marketers of the PFA tablets heavily promoted their use in conjunction with the shift to plastic tubing. The projected increases in sap production from the use of PFA pellets together with plastic tubing were enormous and potential game changers. As with plastic tubing, the use of a chemical aid was viewed by some as simply modernization with the aid of science and technology. Some may even say, better living through chemistry, as the Dupont advertising slogan went. In fact, as noted above, one of the three manufacturers of the PFA pellet was Bob Lamb, the maker of Lamb Naturalflow, tubing, who became the most influential manufacturer and promoter of plastic tubing in the United States during the 1960s and 1970s.

Advertisement from 1964 for the Ma-pel brand of paraformaldehyde tablets as sold by Bob Huxtable’s Sugar Bush Supplies Company out of Lansing, Michigan.

The pellets were clearly effective in slowing microbial growth and increasing and extending sap flows during the tapping season; however, several researchers and producers recommended against their use due to the adverse effects of the pellets on the short- and long-term health of the trees. In addition, the mere use of the word “formaldehyde” in association with food production was very unpopular with consumers. Combine that with a growing interest by the maple syrup industry in organic production, labelling, and marketing put the use of PFA pellets further out of favor. At the same time, there was strong push-back from some corners within the industry that the pellets were harmless. Not surprisingly support for the use of PFA was especially strong from the large producers and manufacturers of the pellets, most notably from the influential Robert M. Lamb and Reynolds family, with Lynn Reynolds, serving as the President of the International Maple Syrup Institute at the time.[4]

Ultimately, the state of Vermont appears to have been the first government (state, federal, or provincial) to formally ban the use of PFA pellets, reportedly doing so around 1982. It is interesting to note that a number of references make the claim that Vermont led the way with a ban around this time, yet I have been unable to identify and document the regulatory action or Vermont statutes to support this claim and this date. Likewise, I have been unable to find any news reports from that time announcing the action of the State of Vermont. This is not to say that I don’t believe that the State put in a ban of some sort, rather, it is remarkable that it has been so difficult to verify the details and date of that regulatory action.

By the end of the 1980s, two decades of research demonstrating the ill-effects of the pellets on forest health and sugarbush productivity had convinced most producers to discontinue their use. At the federal level in the United States approval for distribution of PF for use in the maple industry was cancelled by the end of 1989, effectively banning its use. In Canada registration for the use of PF expired at the end of 1990, effectively resulting in a ban on its use beginning in 1991.

Banning of the PFA pellet in the United States was specifically carried out in two ways. First through the voluntary cancellation by the registrants of approval to distribute PFA pellets. Approval to distribute had previously been awarded by the EPA to the three companies manufacturing the pellets. In 1986 Reynolds Sugar Bush, Inc. (Sapflo) cancelled their registration, while Lamb Natural Flow, Inc. (Flomor) and Sugar Bush Supply Company (Ma-pel) both cancelled theirs in 1989. In addition, in 1999 the EPA revoked the previously established tolerance level for residues of paraformaldehyde in maple syrup with publication of the revocation as a final rule in the Federal Register.

In Canada the last registered product containing paraformaldehyde for use as an antimicrobial agent in maple syrup expired on December 31, 1990, effectively making its sale, purchase or use illegal after that date. However, a maximum residue limit of 2 ppm of paraformaldehyde in maple syrup remained on the books until a proposed revocation in 2010. From time to time, examples of its continued use have appeared in the news.For example, investigations in Quebec in 2001 discovered continued use of PFA pellets by sugarmakers with evidence of PFA pellets found at 21 of the 50 sugarbushes visited.[5]

The Origins of the Maple Syrup “Nip” Bottle

Maple producers have been packing maple syrup into miniature glass bottles since at least the 1930s with many early bottles being used and marketed as trial-sizes or individual servings sample bottles to get people to try a particular brand. Folks not familiar with the flavor and taste of real maple syrup could buy or be given a sample size bottle to see if they liked it rather than jump in for a larger bottle. More recently small bottles of the 1.5 to 2.0 ounce sizes have been used and sold as more novelty bottles and complimentary favors for weddings, parties, businesses and as conveniently sized stocking stuffers.

The Cary Maple Sugar Company’s brand of Highland Syrup was bottling their syrup in 2.0 ounce minis since the late 1930s. At one point the company even devised a plan and set up for refillable bottles. Small sample size bottles would be distributed and sold at restaurants and hotels and then the satisfied customer could return to refill their small bottle at unique syrup dispenser.  Similar in appearance to a water cooler, a large glass jug of Highland Syrup was suspended upside down and the small empty Highland bottle was refilled through a spigot below.

Miniatures maple syrup bottles are sometimes referred to as nips which is a name that comes from the more common miniature hard alcohol bottles from which one might take a “nip” or small sip. The term “nip” supposedly has its origins in the word “nipperkin” which meant a small measure of spirits or a measure of alcohol less than a half pint. The word may also have come from the Low German and Dutch word of nippen which means to sip or taste. Hard alcohol nips in the form of miniaturized versions of popular and recognizable bottles and labels of spirits like whiskey, gin, vodka, and various liqueurs have been around since the early part of the 20th century.

In the late 1940s or early 1950s one particular maple syrup producer in Minnesota got the idea to create a novelty label for small bottles of syrup that was a play on the nip size and the name of a few popular and better-known whiskeys and bourbons. In a 2002 interview I conducted with the late Sherman Holbert, he shared that he had been bottling syrup for a few years in the late 1940s in whatever glass bottles he could find, since following the war, specialty glass was hard to come by. Holbert’s maple business, Mille Lacs Maple Products, often reused old pint and half pint liquor bottles for packing syrup, thoroughly cleaning and scraping off the labels before putting on his own maple syrup company labels.

His company was doing a great business selling small gift-size bottles for corporate clients when one day while removing the label from a used whiskey bottle the idea came to him to put the familiar shape and size of those small booze bottles to use and add a novelty name and label. Holbert’s first novelty label was “Old Grand Mom” playing off Old Grand Dad whiskey. He followed that with another label, which became the more popular “Northern Comfort” which was a play on the name of Southern Comfort whiskey.

Holbert’s maple syrup company was relatively short lived, ending in 1952 but the idea of novelty miniatures or nips using take-offs of popular whiskey and bourbon labels has continued to this day and the label of “Northern Comfort” stuck.

Other companies like Maple Grove, Inc. and American Maple Products in Vermont have used the “A Nip of Northern Comfort” label on novelty, nip-sized bottles in the past, and it is still used today by the Smokey Kettle Maple Company out of Ontario.

The Reynolds Sugar Bush used “Sudden Discomfort” as their own unique take on it. In addition to “Sudden Discomfort”, Reynolds Sugar Bush had a whole line up of novelty labels including Old Croak, Old Polecat, Old Grand Gag, Old Old Hound Dog, and Hawg & Hawg.

Today, most “nip” sized and shaped miniature syrup bottles are used as gifts and favors for guests to special events but their origins are actually in found in the bottom of an empty whiskey bottle.

The Reynolds Sugar Bush used “Southern Discomfort” as their own unique take on it. In addition to “Southern Discomfort”, Reynolds had a whole line up of novelty labels including Old Croak, Old Polecat, Old Grand Gag, Old Hound Dog, and Hawg & Hawg. Interestingly, in his 1998 history of the family and its business Reynolds, Maple, and History: Fit for Kings,” Lynn Reynolds suggests that most of the ideas for novelty packaging, including the bottles “imitating beer, wines, liquors, and other beverages” came from his father Adin Reynolds. Unfortunately, this claim, which may in part be true, is not accompanied by any supporting dates or documentary evidence. Consulting the 1963, 1964 and 1967 equipment and sugar maker supplies catalogs in my collection from Reynolds Sugar Bush one does not find examples of novelty glass containers among the items offered, suggesting Reynolds’ sale and promotion of novelty nip bottles came at a later date.

The Era of Plastic Sap Collection Bags

Prior to the modern method of collecting maple sap with flexible tubing there was an earlier attempt to put plastic to use as sap collection bags. The first reusable plastic sap collection bag was invented by Everett I. Soule of the George H. Soule Company the well-known maple equipment manufacturers out of St. Albans, Vermont. Following the Soule Company’s primary brand name for their King evaporator, when the bag came on the market it was sold as the King Sap Bag.

Clip from a 1956 advertisement for the Soule Company King Sap Bags.

Everett Soule began developing and experimenting with his bag idea in the mid-1940s and by October 1950 had perfected a design for a 13 to 15-quart bag that was then distributed to Soule Company equipment dealers around the country for sale and first-time use in the 1951 sugaring season.

The King bag was made of a transparent, heavy plastic called vinylite that was said to be the same material used by the Air Force for the packaging of food and water drops to soldiers. The bags were simple to use and did have the advantage of being cheaper than new pails and covers and when flattened for storage took up considerably less room than an equal number of pails. The top had an open flap that allowed one to pivot the bag on the spile to empty the collected sap without taking the bag off the tree, at least in theory.

The transparent plastic allowed one to easily see the sap volume in the bag and did allow sun through to provide some ultraviolet light that arguably led to reduced microbial development and clearer, cleaner sap. Use of the bags required one to employ a hookless spile, such as the Soule hookless spout. When first introduced in 1950-51, prices for the bags were for anywhere from 69 to 89 cents each for lots of 100 or more with 100 Soule spouts also available for $8.00. Although these were said to be made of a durable plastic that could withstand the extreme weather conditions of the tapping season and the significant temperature fluctuations, it was still early in the use of plastics. The late Bob Coombs informed me that the cost of the King Sap bag was actually more like $1.25 a bag and they tended to get brittle and crack and split after a season.

Everett I. Soule’s 1960 design drawing for Canadian patent 598853.

Everett I. Soule obtained a patent in Canada for his sap bag (CA 598853) in May of 1960, but it does not appear that a US patent was ever secured, despite marketing language of patent pending. At the time of his invention, Everett I. Soule was the president of the George H. Soule Company, having taken over as president in 1938 following the death of his uncle and company founder, George H. Soule in 1937. Along with his brother Raymond L. Soule, Everett continued run the family owned company and himself became a prominent individual in the maple industry for many years. Following his death in 1964 the Soule Company was sold to Leader Evaporator Company, including the manufacturing and sale of the King Sap Bag. Under Leader’s ownership the printing on the exterior of the bag was changed from George H. Soule Co. to Leader Evaporator Co., Inc.

Initially, the maple industry showed great enthusiasm for this radical invention and introduction of plastics, then a post-war technological wonder that was sweeping the world. In an industry that previously was limited to wood and metal, plastics showed great promise, but it was the arrival of flexible tubing at the end of the 1950s that a meaningful shift in technology was to come.  The King Sap Bag continued in production into the late 1960s, but by the 1970s it was essentially abandoned.

However, another variation of the plastic sap collection bag came along a few years later and has had a more lasting impact, especially among backyard sugarmakers and hobbyist. Unlike the reusable King Sap Bag that was washed, dried and stored at the end of the season, this bag was a single season disposable model that hung on a metal frame. Invented by Adin Reynolds of the Reynolds Sugarbush in Aniwa, Wisconsin in 1958 the Reynolds Sap Sak first became available for commercial sale in 1966.

Design drawing from Adin Reynolds’ 1967 United States patent 3,304,654.

The Reynold Sap Sak was distinctive with its bright blue bags, although it is possible to use a clear plastic bag as well.  Unlike the King Sap Bag, the Reynolds bags were simple, thin and very inexpensive plastic bags that were designed to be thrown away at the end of each season.  The thinner bags were a little more prone to splitting when the sap froze on cold nights and squirrels were known to gnaw through a few corners, but the extremely low cost of bags made the occasional installation of replacement bags acceptable. Like the King Sap Bag, the Reynolds Sap Sak also worked best with a hookless spile, since the metal cover was designed for fit over the spile and have its weight supported directly by the spile.

The Reynolds Sugar Bush initially promoted their bag through their Wisconsin equipment dealership and in 1967 Adin Reynolds was awarded a patent for this invention. In time, with its popularity and demand it began to be carried and supplied by nearly all maple equipment dealers. The Reynolds Sap Sak is still sold and in use across the U.S. and Canada but probably sees greatest use in the upper Midwest where it was first introduced. It is also possible that for the smaller scale producers not choosing to use tubing there is less of a concern for appearance or a romanticism about the aesthetics of sugaring in Wisconsin or Minnesota or Michigan that one might find in New England and a blue plastic bag is a perfectly acceptable way to gather sap.
