Product Demo: Boiling on a Lapierre Hyperbrix rig with 35 percent concentrate

Today we are at the UVM Proctor Maple Research Center in Underhill Center, Vt. with center director Dr. Timothy Perkins, Jean Francois Goulet of Lapierre Equipment and Proctor’s Abby Van Den Berg, boiling on a Lapierre HyperBrix system with 35 percent concentrate. The new technology takes out 2/3rds of the water from the sap before it hits the evaporator. Lapierre donated the equipment to the Proctor center to support research. Van Den Berg’s findingsÑfollowing a blind taste test last fall with a group of volunteersÑ found there is no noticeable taste difference between syrup produced in a high brix process vs. conventional syrup.

Is Tapping Below the Lateral Line A Good Idea?

This research was conducted to determine whether tapping below the lateral line in vacuum tubing operations results in the same quantity of sap from a taphole as normal (above the lateral line) tapping, and thus whether tapping below the lateral is a reasonable management alternative which might be employed to increase the size of the tapping band in maple sap production. It will also inform us as to any tradeoffs (reductions) in yield that might result from this approach.

Ask Proctor

Q1: I’m considering switching from a flat pan to a larger pan with continuous flow, and keep hearing about the gradient. What is a gradient and why is it important? Q2: After a warm spell that made the sap stop running, a hard freeze made it start again so I collected and boiled. The syrup had an off-flavor. Why?

A Summary of Research to Improve Vacuum in Maple Tubing Systems

Research conducted at the University of Vermont Proctor Maple Research Center over several years to explore a variety of methods to potentially increase sap yields from tubing systems through modifications of the lateral/dropline portion of the sap collection system.

Taphole Injury in Red Maple

Maple tapping guidelines, which specify the number of taps in relation to bole diameter, and the spacing and depth of tapholes, have been devised primarily using sugar maple wounding as a model. With its importance as a present and future resource for maple sap, it is critical that we extend our knowledge about taphole wounds to red maple so that, if necessary, these guidelines can be revised to include the proper and sustainable tapping of this species.
