Estimated potential revenues from adding birch syrup production to an existing maple operation
An Excel spreadsheet that can be used to determine the potential yields and profit from producing birch syrup.
Maple water: A first look
As the maple water industry has grown, this study conducted a taste test of various brands of commonly available maple waters.
Birch can help increase your maple operation profits
Birch syrup production uses the same equipment as maple syrup production, and the spring sapflow season begins just as the maple season is ending. Sugarmakers might want to consider adding birch production to their operations to generate additional revenue.
Chemical composition of five standard grades of pure maple syrup
The objective of this study was to characterize the chemical composition of the five maple syrup grades, including their pH, conductivity, mineral and carbohydrate contents. In general, quantification of the range of chemical composition for each standard maple syrup grade will strengthen the existing knowledge of maple syrup chemistry.
Measuring Sap Flow
Keeping track of the amount of sap being collected is important for maintaining high yields and minimizing losses. This article explains how to measure sap using counters mounted on releasers.
The 3/16 phenomenon
Using smaller-diameter tubing can create a natural vacuum which can increase sap production. This article details some research into this method of sap collection, and offers tips on some practical applications.
Testing tapping depth vs. sap yield
Results from research into the impact of tap hole depth on sap yield.
Does sugar removal impact trees? A complex question to answer.
Two main issues relate to the sustainability of maple sugaring; tree wounding and sugar removal. In other words, does a tapped maple tree grow more wood than is compartmentalized (functionally “removed by the tree’s normal wound response process) each year and/or does sap collection take more sugar from the tree than can be readily replaced through photosynthesis? These two issues, although separate in some respects, are inextricably intertwined.
Cloudiness’ effect on refractometer measurements
Accurately measuring density is critical to the production of pure maple syrup. This article explores how impurities in syrup can affect the accuracy of tools used to measure density.
