Keys to High Yield
Actual yields in many maple operations are often lower than those achievable under optimum conditions. Dr. Abby van den Berg, Research Associate Professor with UVM’s Department of Plant Biology and Proctor Maple Research Center, presents practices to narrow this gap, from tree to sugarhouse.
Renting Taps to Enhance Viability
Can access to more taps improve your business? Do you own forest land that you’d like to lease to sugar makers? Mark Cannella, UVM Extension, provides information on leasing taps and different approaches to setting rental rates. He also shares the new UVM Sugarbush Lease Guide and Sugarhouse Lease Guide with participants.

How to collect the most sap possible using efficient techniques.
Drought Stress and Water Availability for Maple Sap Production: A Correction
Sap flow and stem pressure in sugar maples during winter dormancy depend on the expansion and contraction of gas bubbles. These gas bubbles are primarily located in the libriform fibers of wood tissues, not in the xylem vessels. Though there are gas bubbles (embolisms) in the xylem vessels, these bubbles are not the dominant drivers of stem pressurization.
Increasing Syrup Production by Re-tapping During the Sap Season
Work done at the Uihlein Maple Research Forest in Lake Placid during the 2018 and 2019 maple syrup season looked at timing of tapping to best capture the most amount of sap. During this study it was found that trees tapped in late March did not yield as much syrup since they missed early sap runs. Trees tapped in January were able to capture early season sap runs but yield diminished slightly near the end of the season due to microbial plugging.
Sap sugar within, between seasons at UVM PMRC
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.
