A knowledge of variation in sugar content is significant in any program aiming at improvement of existing maple stands. Certainly a factor which cannot be overlooked in making thinning recommendations for a producing stand is the sap quality of the maple trees under consideration. Respective yields, which are related to sugar content of sap as well as to amount of sap produced, must be taken into account.

Although maple dieback has received considerable recent attention in the Northeast, little has been reported about the relationship between sap sugar yield and crown health or crown nutrition. We measured sap sugar concentration (sweetness) in six northern Vermont maple stands in the springs of 1990-1992, and sap volume yield from tapholes at one stand in 1991. The stands differed in average crown dieback, canopy transparency, density, and mean dbh, as well as cation exchange capacity (CEC) of upper soil horizons.
Tapping walnut trees for sap collection and syrup production provides a syrup producer the opportunity to tap into the new, growing, and potentially lucrative specialty tree syrup market. The bulk price for walnut syrup in West Virginia this past season ranged from $150-$250/gallon, with retail sale prices topping $500/gallon (Tonoloway Farm, 2020). To get there, potential walnut syrup producers need to know how and when to tap their trees to maximize sap production. During the 2020 sap flow season, Future Generations University, with a grant from the NE SARE program, conducted studies looking at the application of vacuum, spout design, tapping procedures, and the timing of sap flow in walnut trees. This paper presents part of the findings of that work.
A 107 tap study area was established at John DalenÕs farm in Franklin WV. At this site we carried out a series of trials to learn about walnut sap flow, and to address sap and syrup production issues as they arose. We also collaborated with walnut sap producers in Palestine and Leon WV, and with Virginia TechÕs Catawba Sustainability Center in Blacksburg VA. The analysis section of this report is based on the work done at the Dalen farm study area.
By tapping the trees for sap collection, it may be possible to create value from the beech trees in your forest.
Weather conditions are the single most important factor affecting sap production in the sugar maple. Weather forecasts, therefore, can be a very valuable tool for maple syrup producers.
Do you sell your maple products or give tours at your sugarhouse? Is your sugarbush open for hiking? Thinking about it, but not sure? Join us for a discussion about marketing, safety, liability, and other considerations. We’ll share information (and let you know how to get free signs) for Maple 100, Open Farm Week, and the new agritourism limited liability statute – and we’ll make time for a round robin about what would be most helpful for your sugaring operation.
The first part of this book is a set of guidelines that follow the West Virginia Department of Agriculture’s Sugaring Operations Inspection Checklist. The checklist is what is on the clipboard of the state compliance officer should you ever get or need a WVDA review certificate. The second part of this book presents a Decision Tree and Regulatory Matrix that you can follow to help you comply with state and federal regulation that apply to your production and sale of maple syrup.
