In attempting to establish criteria for organic certification of maple operations, there are still some wide disagreements among certifying agencies over how to regulate behavior that is unique to maple.
There are a variety of reasons why sugarmakers might want to tap earlier than the traditional date: thousands of taps that take several weeks to install, lower snow cover and easier walking before mid to late winter, climate change generally moving the season forward and providing more sap flow weather in January and February. For most sugarmakers, the bottom line is simply this: what tapping time frame results in the highest sap yield? The experiments described below, which were performed between 2000 and 2007, were designed to answer this question.
This aim of this project was to determine whether early spout and dropline deployment before tapping could be used while maintaining good sanitation levels and high sap yields.
In recent years, research at Cornell University’s Uihlein Maple Research Forest has looked at ways to maximize maple sap production through tapping practices such as spout selection, re-tapping and timing of tapping.

We initiated a controlled test of the effect of in-line UV light on the microorganisms in free-flowing sugar maple sap that had not been treated by PFA pellets at the taphole. We also wanted to test the effect of temperature-controlled sap storage for five intervals up to 7 days (167 h) prior to processing to syrup.
There are several important factors that affect the yield of sap from trees during the production season. One relationship that is sometimes overlooked is the one between tree size and yield. In order to develop models of tree size and yield to answer some of these questions, we measured the sap volume and sugar content from approximately fifty individuals along a wide range of sizes during the 2016 and 2017 seasons.

A wide variety of cleaning techniques are currently used in the maple industry, including rinsing the system with pressurized air and water, or attempts to sanitize with chemical solutions such as peroxide, bleach, or alcohol. However, the effectiveness of these cleaning techniques in reducing microbial populations and increasing annual sap yield is often questionable.
