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.
A New Method for Pricing Sap
While you may think that sap pricing should be relatively simple and easy to understand, there are actually many factors that can and should affect sap prices. This article presents a new method for pricing sap and explains how it differs from the traditional pricing guidelines that have been posted annually in the Digest.
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.
Procedures for Neutralizing Maple Wash Water
Wash waters resulting from the use of cleaning chemicals for reverse osmosis (RO) membranes and evaporator pans are often strongly basic or acid, and should be neutralized before disposal in order to comply with Vermont Department of Environmental Conservation regulations. These instructions for neutralizing maple wash water will allow you to modify your used maple cleaner to a safe pH range.
Maple Syrup Production in a Changing Environment
This report summarizes the results from a survey to document respondent’s experience of changes within maple syrup operations and sugar maple (acer saccharum) ecosystems, including potential changes to regulations, technologies and climate.
How deep do you tap?
An investigation into the impact of tap hole depth on tree health.
Expanding trees: diameter growth in sugar maples
Tree growth rate can be an important indicator of how well the tree will heal from tapholes.
The state of the maple industry – 2011
A summary of the current state of maple production in New England is based on surveys returned from approximately 220 sugarmakers in April, 2011.
Identification of Microbial Spoilage in Maple Syrup Samples
An increasing number of maple syrup samples containing floating masses or surface mold have arrived at the University of Maine Cooperative Extension. Conventional practices have been to discard obvious mold growths, reboil and consume the syrup. This practice may be risky, especially with the increasing number of food borne illness outbreaks with other food products.
