Why do some maple trees produce more sap?
Many researchers, in addition to many sugarmakers, have observed that there is a great range in the amount of sap produced from individual trees in a forest. Understanding, and perhaps predicting the different performances of the trees in a sugarbush is an aspect of maple physiology that remains fascinating.
Pricing sap
How much money should you expect to make selling sap? There are many factors to consider.
Conducting and understanding experiments in maple operations
Research studies must follow certain rules in order for the findings to be valid. This column discusses a few of these simple rules: comparison of treatment vs. control, replication, dealing with natural variation, and statistical validity.
2010 Sugaring Season Survey
In mid-April 2010, an invitation to participate in a survey was sent to subscribers of two maple forums. The survey was designed to get some basic information about the operations of the respondents, to describe sanitation practices (changing tubing, spouts, etc.) and to get feedback from users about the Leader Check-valve adapter.
How do I test the quality of my homemade maple syrup?
Demonstration on how to test when sap becomes maple syrup. Different tools are discussed.
Costs and Returns with Vacuum Systems
A spreadsheet to calculate costs and returns of using vacuum sap collection systems.
Energy use in maple operations
A summary of a presentation on energy efficiency in maple production.
Are used maple spouts and new spouts equal?
Research results from experiments on sap yield using new and used spouts.
