As the US domestic maple syrup crop continues to grow the influence of different scales and types of business can shape local communities and national trends. Survey results presented here demonstrate the dramatic difference in the scale of maple enterprises as represented by tap count and the resulting working forest acres these businesses utilize.
Tapping depth strongly influences both sap yield and wounding. Numerous studies have focused on the amount of sap produced with ifferent depths, the most extensive work conducted by Morrow (1963), who found a tendency for increasing sap yields with increasing taphole depth. However, this work was conducted on gravity with 7/16” tapholes, so is less informative to most producers using 5/16” spouts and vacuum.

How to collect the most sap possible using efficient techniques.
Changes in the amount of sugar in maple sap vary within a sap run, from day to day, throughout the season, and from year to year.
Presentation about organic maple defoamer research.
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.
