More then a decade ago there was a renewed realization that microbial contamination of maple sap collection systems was having a significant detrimental impact on sap yields. Several research studies to investigate ways to improve sap yields from tubing systems were undertaken at both the University of Vermont Proctor Maple Research Center (Underhill, VT) and at the Cornell University Arnot Forest (Van Etten, NY) starting at about the same time and proceeded both as independent and joint projects from 2009-2018. The results of many of these studies have been reported in the past in numerous individual publications and presentations. This article seeks to combine and present this extensive body of work into a single, comprehensive, but concise summary of our results.

During the 2019 maple season the Cornell Maple Program conducted replicated trials on 5/16Ó and 3/16Ó tubing looking at a variety of tubing options for taphole sanitation and tapping. This report will focus on the 5/16Ó results.

The effects of spout and tubing sanitation on maple sap yields
One of the more common questions producers have when about tapping maple trees is Òhow deep should spouts be driven in to the taphole?Ó. Unfortunately, there is not a simple answer, since different spouts have different dimensions, variable degrees of taper and steps, and are made of different materials with dissimilar degrees of Òstickiness.Ó Regardless, the importance of driving spouts in to the proper depth is readily apparent: if spouts are driven too shallow there is a risk that spouts can leak vacuum or heave easily during freezes, but if driven too deeply, small cracks may form which cause liquid and vacuum leaks or alternatively, the reduced amount of exposed wood surface area inside the taphole caused by driving spouts in too deeply may reduce sap collection.

In order to determine the optimal approach to sap collection in their operation, maple producers need to be informed about how the choices they make will affect sap yield. One of the decisions they face is what spout size (diameter) to use.
