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.
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.
What’s trending
The 2012 USDA Census of Agriculture reveals trends in growth for number of producers and number of taps in many states.
Using Smartrek’s vacuum monitoring system
Evaluation of wireless system to monitor vacuum in subing systems.
Growth Rates of Sugar Maple Trees Tapped for Maple Syrup Production Using High-Yield Sap Collection Practices
The amount of sap that can be extracted annually from trees for maple syrup production using current equipment and practices is more than double the typical yields achievable when current maple industry tapping guidelines were developed. The growth rates of trees tapped with these Òhigh-yieldÓ practices at 18 sites in Vermont were measured and evaluated to determine whether they were sufficient for the replenishment of conductive wood to remain at sustainable levels when current tapping guidelines are followed.
Preliminary Results of Sugar Maple Carbohydrate and Growth Response under Vacuum and Gravity Sap Extraction
Recent technological advancements have increased the amount of sugar-enriched sap that can be extracted from sugar maple (Acer saccharum). This pilot study quantified overall sugar removal and the impacts of vacuum (60 cm Hg) and gravity sap extraction on residual nonstructural carbohydrate (NSC) concentrations and on stem and twig growth.
Comparison of Digital Refractometers for Use by Maple Producers
The purpose of the present experiment was to test the precision of a variety of digital refractometers available to maple producers. Additionally, the effect of temperature on refractometer accuracy and precision was investigated, in order to assess the reliability of the automatic temperature compensation feature now present in the majority of refractometers.
Recent trends in the maple industry IV – bulk syrup prices
This research shows the trends in bulk syrup prices in the U.S. and Canada between 1998 and 2015.
Effects of Sap Concentration with Reverse Osmosis on Syrup Concentration and Flavor
Between 2008 and 2011 we conducted a series of controlled experiments performed with commercial maple equipment to investigate the potential effects of the use of RO on the composition, properties, and flavor of the maple syrup produced.
