North American Maple Syrup Council
The North American Maple Syrup Council is an international organization, founded in 1961. The purposes of the Council are to promote research in the chemistry and technology of maple sap and the products derived from it; in sugarbush management an...
The sugaring season has been over for a while. Maple trees ended their annual period of dormancy when their winter buds broke, allowing new leaves to emerge. These lush green leaves are now working to produce all the energy needed for the tree to ...
Why Does Sap Flow from Maple Trees? Throughout the maple region, there are several weeks of alternating freeze and thaw temperatures each spring. This weather provides the right conditions for sap flow in maple. Unlike most trees, maples have tiny...

A modern maple operation relies on a tubing system with vacuum to maximize sap production. The innovation of plastic tubing originally came as a labor-saving device and not to increase sap yield from individual trees. As the materials used to prod...
Diatomaceous Earth (DE) Filtering
Just as the sugars found in sap become concentrated during boiling, so too are the naturally occurring minerals found in sap. As the concentration of minerals increases in the sap, it approaches, then exceeds the point of saturation. When that hap...
As trees form, the size and shape of its stem and crown, will be impacted by living in a low light environment such as the forest's understory. So-called suppressed trees are able to capture just enough sun to survive. Sugar maples growing in the ...
Although bucket spouts are still available, most spouts used in the maple industry currently are plastic and designed to be used with vacuum. Spouts are constructed of food-grade nylon or polycarbonate and are smaller in size (5/16" diameter) than...
