Exudation Pressure in Maple Trees: Comparing Simulations with Experiments
Exudation is the process whereby trees can generate a large positive pressure in stems or roots during months when the tree is leafless and mostly dormant and temperatures fluctuate above and below freezing. This article aims to provide an update on recent modelling efforts
in combination with experimental measurements from red/sugar maple trees at the University of Vermont Proctor Maple Research Center that validate the model results.
Fertilization of Sugarbushes Part I: Physiological Effects
The goal of this project was to examine the effects of liming and fertilization on tree physiology, growth and sugar production of a moderately fertile maple stand. In this first report, we describe, in general terms, the study area, treatments, and results of liming and fertilization on tree physiology and growth.
Fertilization of Sugarbushes Part II: Sap Volume and Sweetness
In this article we describe the effects of fertilization and liming on sugar production in maple stands.
Field Evaluation of the Small Diameter Spout for Maple Sap Collection
Beginning in 1999, a newly introduced maple sap spout for use in smaller diameter tapholes was evaluated at Cornell University’s Uihlein Sugar Maple Research/Extension Field Station near Lake Placid, New York. After two sap production seasons, no significant differences were found in sap volume yield and sap sugar concentration in maple sap collected with the small diameter spout compared with that of the conventional sap spouts.
Getting it right: Achieving highest quality through accurate density measurement
Accurately measuring the density of finished maple syrup is an important task for commercial syrup producers.
Getting the taste right: Metabolism off-flavor taints maple syrup
Knowing how to detect and avoid metabolic off-flavors is critical to producing high-quality syrup.
Grade Blending: A New Calculator to Get Blended Syrup in Grade
The Cornell Maple Program has developed a new, user-friendly tool to calculate how much of each syrup you would need to blend. This calculator will only help sugarmakers using digital light meters that give the percentage of light transmittance (%Tc) through your syrup.
Gravity Filtering: Simple tools and techniques for filtering small batches of maple syrup
To ensure that your maple syrup is the best it can be, filtering out contaminants before packing is critical. Using paper and cloth filters to do so is an acceptable and inexpensive option.
Gravity Filtering: Simple tools and techniques for filtering small batches of maple syrup
Many producers use a filter press, which uses a pressure pump to push the syrup through a series of metal plates and frames, separated by single-use pieces of filter paper which capture the particles and result in crystal-clear syrup. For smaller producers, however, using paper and cloth filters and letting gravity pull the syrup through is an acceptable and far less expensive option.
