Sap Collection from Small-Diameter Trees
For several years, we conducted research on the collection of sap from small-diameter maple trees. This document outlines the basic concepts, techniques, and applications of this type of sap collection.

Do Not Use Isopropyl Alcohol as a Maple Sanitizer in the U.S.
Regardless of the availability and guidance provided, maple producers should clearly understand that the use of isopropyl alcohol in maple tubing systems anywhere in the United States is a violation of federal law.
Evaluating Processing Methods to Produce Safe, Shelf Stable Maple Sap Beverages for Small Operations
In order for sugarmakers to take advantage of the newfound interest in maple sap beverages, processes must be developed that would allow small scale producers to process and package maple sap safely, efficiently, and economically. We investigated several methods that might be employed for seasonal markets during the harvest season of January-April.
Taphole Injury in Red Maple
Maple tapping guidelines, which specify the number of taps in relation to bole diameter, and the spacing and depth of tapholes, have been devised primarily using sugar maple wounding as a model. With its importance as a present and future resource for maple sap, it is critical that we extend our knowledge about taphole wounds to red maple so that, if necessary, these guidelines can be revised to include the proper and sustainable tapping of this species.
A Summary of Research to Improve Vacuum in Maple Tubing Systems
Research conducted at the University of Vermont Proctor Maple Research Center over several years to explore a variety of methods to potentially increase sap yields from tubing systems through modifications of the lateral/dropline portion of the sap collection system.
How Will Climate Change Affect Maple Syrup?
The Acer Climate and Socio-Ecological Research Network (ACERnet) formed recently to study climate impacts on sugar maple and maple syrup production. With funding from the Department of Interior Northeast Climate Science Center, we are focusing our research on the relationship between sap quality and climate, and how producers can and are adapting to climate variability and change.
Investigating Decreasing Growth Rates of Sugar Maple in the Adirondacks
Relatively little work has been conducted investigating trends and influences of the annual growth of sugar maple trees, utilizing the widths of tree rings to estimate growth rates for each year. Using this tree-ring approach, recent research suggests that growth rates have been decreasing in the Adirondack Mountains of New York State.
What’s trending
The 2012 USDA Census of Agriculture reveals trends in growth for number of producers and number of taps in many states.
