Bark removal and taphole closure with arc-barb spouts
The Arc-Barb Spout (UVM Patent Pending) is designed with a shortened barrel to allow improved sap flow from the shallower, more productive sapwood zones in maple stems.

Effect of spout deployment date and drop configuration on sap yield
Because of the lack of knowledge on this topic and the frequent questions we received about the proper practice, we implemented a study in the summer of 2022 to examine the single and interactive effect of spout deployment date and open verses closed drops on sap yield.
Estimated potential revenues from adding birch syrup production to an existing maple operation
An Excel spreadsheet that can be used to determine the potential yields and profit from producing birch syrup.
Results from the 2014 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.
A model of the tapping zone
This article is intended to accompany the Tapping Zone Model available to download at the University of Vermont Proctor Maple Research Center (UVM-PMRC) website. It provides a general explanation of the model and how it can be used. The model can be used to estimate the chances of hitting conductive and nonconductive wood when tapping, and this can be used to assess the sustainability of current or planned tapping practices.
Sap Collection from Small-Diameter Trees
For several years, PMRC researchers 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.
Effects of spout and drop sanitation strategy on sap yield and net profit
An Excel spreadsheet that can be used to determine the effects of replacing or cleaning spouts and droplines on sap yield and profit.
Birch syrup production to increase the economic sustainability of maple syrup production in the Northern Forest
A presentation on the potential value of adding birch syrup production to an existing maple operation.
Tapping guidelines for current sap collection practices
Research into whether existing tapping guidelines are appropriate to use with ‘high yield’ sap collection practices which remove a much greater amount of a tree’s sap than older systems.
Results from the 2013 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.
