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.

How to collect the most sap possible using efficient techniques.
Due to the COVID-19 outbreak, many maple producers were forced to cancel open house events during the 2020 sugaring season for the safety of the producers and their customers. This caused a major loss in sales for many maple producers throughout the maple producing region. While COVID-19 is likely to still be a concern for the 2021 sugaring season, we now have a better understanding of the virus and protective measures to keep everyone safe while staying open for business. Those measures and best practices are detailed in this guidance.
Maple farmers experienced a difficult transition when the COVID-19 outbreak in North America resulted in the shutting down of sugarhouses to the public, particularly during some of the most crucial weekends for in-person maple sales. Sugarmakers had to quickly pivot in order to make up for lost sales in the sugarhouse as well as from wholesale restaurant and school accounts. This shift brought about some creative thinking and innovative solutions to reach customers and promote maple products. Some successful marketing, sales and agritourism strategies have not only helped producers recover lost sales, but have permanently enhanced their future sales approach and marketing plans.
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.
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.

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.
