A Model of the Tapping Zone
A model that calculates the proportions of conductive and nonconductive wood in the tapping zone of a tree over time given user-input values for tree diameter and 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.
Growth Rates of Trees Tapped With High-Yield Sap Collection Practices – Are Conservative Tapping Guidelines Sustainable?
The overall objective of this work was to determine whether existing Conservative Tapping Guidelines are appropriate and likely to result in sustainable outcomes when used with sap collection practices that result in higher sap yields.
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.
Chemical Composition of Scale in Maple Syrup Evaporators
The goal of this work was to investigate the chemical composition of the scale that is deposited on maple evaporator surfaces during sap processing. Knowing the chemical composition of scale produced in modern equipment and how it compares to previously published values for loose sugar sand may aid in understanding how best to remove these unwanted deposits.
Tubing Cleaning – Methods Used in the U.S.
A wide variety of cleaning techniques are currently used in the maple industry, including rinsing the system with pressurized air and water, or attempts to sanitize with chemical solutions such as peroxide, bleach, or alcohol. However, the effectiveness of these cleaning techniques in reducing microbial populations and increasing annual sap yield is often questionable.
Defining modern, sustainable tapping guidelines for maple syrup production
A presentation on appropriate tapping guidelines for modern, high-yield sap collection practices.
Relationships Between Tubing System Component Age and Sap Yield: A Preliminary Assessment
Although a number of factors affect maple sap flow in vacuum tubing systems, it has become increasingly apparent that sap yields are largely a function of two major influences: vacuum level at the taphole and taphole and tubing sanitation.
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.
