Since check valve adaptors and spouts reduce sap backflow, this research studied whether or not dropline replacement is as important to improving sap yield when using these taps.
Increasing the yield of sap from maple trees is the goal of most maple producers. While getting there isn’t a matter of one simple thing, by
following best management practices and paying attention to detail it is possible to increase sap yields, often quite dramatically. Includes links to videos.

This article explores the growth of the maple industry in the U.S. as reported in the 2012 Census of Agriculture.
Results from research into the impact of tap hole depth on sap yield.
Using smaller-diameter tubing can create a natural vacuum which can increase sap production. This article details some research into this method of sap collection, and offers tips on some practical applications.
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.
There are several important factors that affect the yield of sap from trees during the production season. One relationship that it sometimes overlooked is the one between tree size and yield.

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.
