Effects of Tapping Depth on Sap Volume, Sap Sugar Content, and Syrup Yield Under High Vacuum

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.

Effects Of The Use Of Paraformaldehyde (PFA) Sterilising Pellets On Sugar Maple Health: A Review

Higher and wider discoloration, compartmentalisation and decay in maple wood by the use of the PFA pellet restricts the healthy sapwood areas and diminishes translocation of sap and nutrients. Furthermore, technological advances for better sanitation in sap collection and storage presently in use by the maple industry, tested by research to be safe for maple tree health and syrup quality, have made the use of the PFA pellet unnecessary.

Expert Tubing Tips for Maple

At Leader’s Spring Open House, three top experts in tubing and woods management – Glen Goodrich, Mark Erlsten, and Jon Rybkiewicz – sat down for a little over an hour and shared loads of invaluable information on all aspects of installing tubing, tapping trees, and best woods practices.

Field Evaluation of the Small Diameter Spout for Maple Sap Collection

Beginning in 1999, a newly introduced maple sap spout for use in smaller diameter tapholes was evaluated at Cornell University’s Uihlein Sugar Maple Research/Extension Field Station near Lake Placid, New York. After two sap production seasons, no significant differences were found in sap volume yield and sap sugar concentration in maple sap collected with the small diameter spout compared with that of the conventional sap spouts.

Getting Started with Small-Scale Maple Syrup Production

Making maple syrup is a time-honored tradition for woodlot owners, and anyone who has even a few maple trees. The process is as simple as boiling sap, but attention to a few details will make for a more pleasant, productive, and safe experience. A warning first, many people who start with just a few tapped trees quickly catch the maple bug; what starts as a handful of tapped trees can expand into hundreds of tapped trees.

Growth Rates of Sugar Maple Trees Tapped for Maple Syrup Production Using High-Yield Sap Collection Practices

The amount of sap that can be extracted annually from trees for maple syrup production using current equipment and practices is more than double the typical yields achievable when current maple industry tapping guidelines were developed. The growth rates of trees tapped with these Òhigh-yieldÓ practices at 18 sites in Vermont were measured and evaluated to determine whether they were sufficient for the replenishment of conductive wood to remain at sustainable levels when current tapping guidelines are followed.
