There are several important factors that affect the yield of sap from trees during the production season. One relationship that it sometimes overlooked is the one between tree size and yield.
Should I use 3/16″ or 5/16″ tubing? One of the first questions maple producers face when deciding to tube (or retube) a sugarbush is whether to use 3/16″ or 5/16″ tubing. This article explains some of the general rules that can be helpful in narrowing down the pros and cons of each approach.
How long can I store sap? Sap is a highly perishable product. This article explains what happens as it is stored, and how to avoid problems.
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.
Filtering syrup in small batches is a huge pain. Any advice on how to make it easier?
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.
Short and long-range weather forecasts can both be useful to determine the proper time to tap. But both also have limitations.
What causes syrup to be light or dark at different parts of the season?
For several years, we conducted research on the collection of sap from small-diameter maple trees. This document outlines the basic concepts, techniques, and applications of this type of sap collection.
Regardless of the availability and guidance provided, maple producers should clearly understand that the use of isopropyl alcohol in maple tubing systems anywhere in the United States is a violation of federal law.
