How does a tree respond to the wound created by a taphole, and what does that mean for future sap production?
Although many analyses of the chemical composition of maple syrup have been conducted, relatively little information exists on the differences in composition of the individual syrup grades. As a first step in acquiring this information we performed a study to determine the characteristic sugar composition of each maple syrup grade.
This educational resource is designed for maple syrup producers, maple sap producers and forest land owners to consider, discuss and formalize lease agreements. This resource is not intended to replace the guidance of a legal professional. The situation for each person and party is different and professional legal assistance is recommended to ensure your business agreements are accurate, appropriate and complete.
Maple production requires sugarmakers possess a diverse set of skills in order to tend the forest resource and maintain a productive sap collection system. Maintaining a healthy, diverse sugarbush that maximizes its growth potential requires periodic vegetation management activity. Also known as thinning, vegetation management is the process of reducing competition for light, water and nutrients of crop trees. Felling trees is the key activity in vegetation management and may be done by logging professionals in support of formal forest management plan objectives or by the sugarmaker or landowner on an as needed basis and including response to extreme weather events.
Business is booming if you own a commercial sugar bush! As forest managers, this means more and more of us are hearing from landowners interested in starting or maintaining a sugar bush. Unfortunately, if you are like us, you did not learn about maple syrup in forestry school. This episode’s guest, Mark Isselhardt, Extension Maple Specialist with the University of Vermont, helps us unpack the fundamentals of sap production, sugar bush management, and how the industry has changed in the 21st century.
The compartmentalization (walling off) process in maple trees and how it affects how to tap for maple syrup production.
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.
This article explores the growth of the maple industry in the U.S. as reported in the 2012 Census of Agriculture.
The University of Vermont Extension’s “New” temperature compensation chart syrup hydrometers. 
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.
