Have you ever wondered why open grown trees produce more and sweeter sap than the ones growing close to each other? To answer these questions, I would like to share with you from my 37 years of experience in forest management.
Occasionally, maple syrup becomes contaminated with floating masses or surface mold. Conventional practices have been to discard obvious mold growths, re-boil and then consume the syrup. This practice may be risky, especially with the increasing number of food borne illness outbreaks with other food products and the resulting negative publicity surrounding these outbreaks.
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.
In 2013 a variety of spout and tubing cleaning and replacement options were tested to determine the extent of sap yield changes that would result. Most of these tests were done at the Cornell Arnot Research Forest.
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.
The Jones “Rule of 86” was devised in 1946 by C.H. Jones, a scientist and educator at the University of Vermont. The gist of the rule is that ifone divides 86 by the sugar content of sap, you can estimate the amount of sap required to produce a gallon of syrup.
Maple syrup is a natural product free of artificial coloring or other additives. Regardless, some publications mention that maple syrup may contain sulfites. In this study, which is conducted by Center ACER in collaboration with UVM Proctor Maple Research Center, direct measurements of sulfites concentration in maple syrup samples collected during 2011 and 2012 were made.
Studies currently underway at the University of Vermont Proctor Maple Research Center (PMRC) are examining the effects of accumulating internal taphole damage on the ability to support future tapping, as well as related subjects such as the effects high vacuum sap extraction might have on tree growth, all with the goal of developing new sustainable tapping guidelines. However, along with focusing on the possible negative effects of tapping and sap extraction, it is important to examine how certain practices might lead to greater sap yields.
In 2012 a variety of spout and tubing cleaning and replacement options were tested to determine the extent of sap yield changes. These tests were done at the Cornell Arnot Research Forest.
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.
