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.
