The Shifting Sweet Spot of Maple Syrup Production: Climate Change Impacts on Sugar Maple Sap

How may climate change impact the maple syrup industry? Our team of interdisciplinary researchers, ACERnet (Acer Climate and Socio-Ecological Research Network), has been working to understand the complex answers to this question for the past several years. In particular, we are interested in examining how climate impacts the timing of the maple tapping season as well as both the quality and quantity of sap collected during the tapping season.

Sugarbush Mapping: Finding information to assist in forest management and planning in the sugarbush

Technological advances by maple equipment manufacturers, continued outreach and education by local, state, federal, and provincial maple organizations, and widespread adoption of new management practices by producers have revolutionized the maple industry over the last 20 years. The design and layout of sap collection systems and advances in vacuum pumps and releasers has resulted in higher per tap sap yields well beyond the old standards. Increased per tap volume has been matched with modern high brix reverse osmosis systems and efficiency gains in evaporators, pushing the economic potential of making maple syrup to new heights. Value-added products, niche marketing and branding, and social media and online platforms, coupled with health conscious and savvy consumers,have altered the retail sales landscape and linked rural maple producers to consumers around the world.

A Decade of Spout and Tubing Sanitation Research Summarized

More then a decade ago there was a renewed realization that microbial contamination of maple sap collection systems was having a significant detrimental impact on sap yields. Several research studies to investigate ways to improve sap yields from tubing systems were undertaken at both the University of Vermont Proctor Maple Research Center (Underhill, VT) and at the Cornell University Arnot Forest (Van Etten, NY) starting at about the same time and proceeded both as independent and joint projects from 2009-2018. The results of many of these studies have been reported in the past in numerous individual publications and presentations. This article seeks to combine and present this extensive body of work into a single, comprehensive, but concise summary of our results.

2019 Cornell Maple Program Research on 5/16åÓ Maple Tubing

During the 2019 maple season the Cornell Maple Program conducted replicated trials on 5/16Ó and 3/16Ó tubing looking at a variety of tubing options for taphole sanitation and tapping. This report will focus on the 5/16Ó results.

The Goldilocks touch: Overdriving spouts reduces sap yield

One of the more common questions producers have when about tapping maple trees is Òhow deep should spouts be driven in to the taphole?Ó. Unfortunately, there is not a simple answer, since different spouts have different dimensions, variable degrees of taper and steps, and are made of different materials with dissimilar degrees of Òstickiness.Ó Regardless, the importance of driving spouts in to the proper depth is readily apparent: if spouts are driven too shallow there is a risk that spouts can leak vacuum or heave easily during freezes, but if driven too deeply, small cracks may form which cause liquid and vacuum leaks or alternatively, the reduced amount of exposed wood surface area inside the taphole caused by driving spouts in too deeply may reduce sap collection.

Working with little ROs for syrup production

One of the biggest drawbacks of making maple syrup for a back yarder or small maple producer is the time it takes to boil the sap into syrup. The idea of using a small reverse osmosis unit to assist with the syrup making is very interesting to many small maple producers. There are many little reverse osmosis systems available for water purification in households or for small commercial applications. These can be purchased from a number of big box stores, home improvement stores or on line. These RO units can be used to remove water from sap to speed up the concentration and syrup boiling process.

Spotted Lanternfly: A New Sugarbush Threat

A new foreign invader could have a substantially negative impact on the eastern North American hardwoods in general, and sugarbushes in particular. The Spotted Lanternfly (Lycorma delicatula, SLF) was first detected near Philadelphia, PA in 2014 and since has spread throughout much of the Commonwealth and has been sighted in about a half dozen New York counties and in several sites in southern New England.

Effect of the new high vacuum technology on the chemical composition of maple sap and syrup

Techniques used to produce maple syrup have considerably evolved over the last decades making them more efficient and economically profitable. However, these advances must respect composition and quality standards as well as authenticity of maple products. Recently, a new and improved high vacuum technology has been made available to producers to achieve higher sap yields. The aim of the present study was therefore to evaluate the effect of this new system on the yield of sap and on the sap and syrup chemical composition.
