Antimicrobial Silver in Maple Sap Collection
Because of a new approach to using nano-silver, the fact that PFA has been banned, and the desire to control microorganisms in maple sap collection systems, the University of Vermont Proctor Maple Research Center investigated the use of spouts and tubing containing antimicrobial nano-silver for suitability for increasing maple sap yield.
Development and Testing of the Check-Valve Spout Adapter
The goal of this project was to find alternative ways to reduce microbial contamination of tapholes. One approach we investigated was to use a check-valve to prevent microbial contamination of tapholes by preventing backward movement of sap from the tubing system into the taphole.
Metabolism Off-Flavor In Maple Syrup – Part II: Remediation of metabolism off-flavor in maple syrup
The objective of this study was to examine several possible remediation techniques to determine which, if any, was most effective in reducing or removing metabolism off-flavor from maple syrup.
Results from the 2009 New England tapping survey
Results of an annual survey conducted of New England sugarmakers, capturing information on production practices and results, such as types of equipment used, sap sugar content, sanitation practices, and other data.
The Timing of Tapping for Maple Syrup Collection
There are a variety of reasons why sugarmakers might want to tap earlier than the traditional date: thousands of taps that take several weeks to install, lower snow cover and easier walking before mid to late winter, climate change generally moving the season forward and providing more sap flow weather in January and February. For most sugarmakers, the bottom line is simply this: what tapping time frame results in the highest sap yield? The experiments described below, which were performed between 2000 and 2007, were designed to answer this question.

Lecanium Scale: What A Sticky Mess!
If you have a sugarbush in the Northeast, you may have noticed brown scale insects, sticky dripping honeydew, and black sooty mold on your sugar maple leaves in 2005 and 2006. That most likely was European fruit lecanium scale, Parthenolecanium corni.
Vacuum Sap Collection: How High or Low Should You Go?
Questions of how vacuum affects maple sap, syrup and trees have existed for many years, and these issues are perhaps more important today than ever before due to the increasing use of collection systems that can achieve very high levels of vacuum. This article will describe recent research performed at the University of Vermont Proctor Maple Research Center that was designed to answer questions about high vacuum.
Temperature Patterns with an Oil-Fired Evaporator
Knowing the temperature in the evaporator is an essential part to making quality pure maple syrup. This article will discuss observations of temperature in each partition and how the front and back pans temperatures are influenced by the draw off events.
