Ten years ago, 3/16” diameter tubing was introduced to the marketplace as an alternative tubing to 5/16” diameter tubing. However, recent research shows that sap production in 3/16” tubing drops off as soon as the second year after installation due to microbial growth. A replacement for 3/16” diameter tubing in gravity systems could be 1/4” tubing. With almost twice the aperture of 3/16” tubing (0.049 sq inches compared to 0.0275 sq inches), 1/4″ inch tubing is less likely to plug from microbes yet is still able to create a full column of sap for gravity vacuum. Quarter-inch tubing is currently not available for maple producers but can be procured from other industries and, with modifications, will work for maple production.
The feasibility of re-tapping maple trees during the sap season was tested in 2019 and 2020 at Cornell University’s Uihlein Maple Research Forest in Lake Placid, NY. This report summarizes that project.
By tapping the trees for sap collection, it may be possible to create value from the beech trees in your forest.
