High Vacuum in Gravity Tubing
Gravity tubing systems are widely used in many small to mid-sized operations throughout the maple region. This article summarizes the past 3 years of my research on gravity tubing, or tubing without a vacuum pump.

2011 Update of Maple Tubing and Taphole Sanitation Research at Cornell
During the 2011 maple sap season a variety of research trials were conducted at the Arnot Forest of Cornell University and in the woods of a number of cooperators both with vacuum and gravity systems. Research conducted over the last five years has shown that significant increases in sap yield can be obtained by keeping the tap hole from contamination by bacteria and yeast.
Relationships Between Tubing System Component Age and Sap Yield: A Preliminary Assessment
Although a number of factors affect maple sap flow in vacuum tubing systems, it has become increasingly apparent that sap yields are largely a function of two major influences: vacuum level at the taphole and taphole and tubing sanitation.
How deep do you tap?

Estimating Twig Starch Content in Sugar Maple (Acer Saccharum): Evaluation of the Visual Technique
Root starch has been used to estimate tree vigor and health with some success. A visual method of starch determination similar to that already used for roots has been undertaken for twigs. If successful, this method would simplify the process of assessing overall tree health and vigor in sugar maple trees.

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.
