The outermost rings of wood in maple trees have the highest sap flow rates and have sweeter sap than the wood found deeper in the tree. We designed a spout that incorporates both a shortened barrel and a series of barbs along the shaft to anchor the spout tightly within the wood and bark tissues.
The University of Vermont (UVM) Proctor Maple Research Center (PMRC) in Underhill, Vermont, has along history of research on sap production. Maple syrup has been made at PMRC since shortly after its founding in 1946, in part for research and in part for demonstration. Syrup production has always been an important component of the work of PMRC as it keeps the faculty and staff aware of the issues involved in sap collection and syrup production, it provides more of a “buy in” from producers when they understand that we face the same hurdles as they do each season, and the revenue gained from the sale of maple syrup helps to fund the operation.
Avoiding tapping near previous tapholes is a common practice in maple production. This is because previous wounds create a zone of stained wood that extends slightly wider and deeper than the taphole, but extends upwards and downwards, often reaching 6-12 inches in length in each direction, affecting a volume of wood approximately 50 times (range of 15-150X) larger than the volume of the taphole (vanden Berg et al. 2023).
Over two-thirds of consumers say that living a more sustainable lifestyle is important to them. Eco-friendly and Fair Trade claims are attractive to consumers, but the marketplace is still trying to clarify what lies behind these claims and if shoppers really follow through with their interests in the form of purchases. Consumer sentiment research looked at retail sales from 2017-2020 and showed that consumer spending on products with environmental, social and governance (ESG) claims grew at a faster rate than products without such claims (Am et al., 2023).
