Tree Size Matters
In order to develop models of tree size and yield we measured the sap volume and sugar content from a wide range of tree sizes during the 2016 and 2017 seasons. This article explores the findings.

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.
Two Pipe Sap Ladder – A Promising Alternative
A two pipe sap ladder consists of a structure of two vertical pipes connecting the lower and upper sections of mainline. It was initially thought that the sap would lift in the pipe on the vacuum side and that air would travel through the pipe on the bush side. Results were not as expected.
Understanding Buddy Off-flavour in Maple Syrup
Acquiring the ability to identify common off-flavours in maple syrup is important for producers. Detecting buddy off-flavour in fresh sap can be difficult, although much easier to taste in finished syrup. Buddy syrup can be described as an unpleasant chocolatey aroma and flavour having a lingering bad aftertaste. Buddy flavour in maple syrup is a food quality issue, not a food safety issue.
Understanding Impacts of Invert Sugar on Maple Products
The level of invert sugar in maple syrup affects how well it crystalizes when making value added products such as maple candy and cream.
Understanding the relationship between tree size and yield
There are several important factors that affect the yield of sap from trees during the production season. One relationship that it sometimes overlooked is the one between tree size and yield.
Update on the Maple Tubing Sanitation Research in Ontario
In the spring of 1998, a research project was initiated to develop alternative methods for maple produces using plastic tubing systems. Although the results are only preliminary, the development of alternative sanitation methods that may reduce reliance on chlorine is looking very promising.
Using Smartrek’s vacuum monitoring system
Evaluation of wireless system to monitor vacuum in subing systems.
UVM Proctor Maple Research Center examines effect of spout diameter on sap yield
In order to determine the optimal approach to sap collection in their operation, maple producers need to be informed about how the choices they make will affect sap yield. One of the decisions they face is what spout size (diameter) to use.
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.
