UVM Sap Pricing Calculator

This spreadsheet can be used to determine the price per gallon paid to the seller for sap or concentrate based upon a finished syrup density of either 66.0, 66.5, or 66.9¡ Brix and calculated using the “Revised Jones Rule” which can be found at: http://www.uvm.edu/~pmrc/jones.pdf

Composition and Properties of Maple Sap, Concentrate, and Permeate

Reverse osmosis is used widely in the maple syrup industry to concentrate maple sap and increase the overall efficiency and profitability of syrup pro-duction. Sets of samples from maple producers utilizing a range of sap con-centration levels were collected and analyzed to provide a portrait of the phy-sicochemical properties and chemical composition of maple sap, concentrate, and permeate across a single production season. The results reinforce that re-verse osmosis functions essentially as a concentration process, without signifi-cantly altering the fundamental proportions of sap constituents.

Ask Proctor

The leaves on the trees are still mostly green and few have fallen. Does this indicate anything for the upcoming sugar season?

Ask Proctor

Will the dry weather affect syrup production next spring?

Check-valve spouts vs. standard clear spouts

Leader Evaporator Co. Check-Valve (CV) spouts and adapters incorporate a small, free-floating ball which is designed to reduce or prevent backflow of sap into the taphole during freezing, when leaks in the tubing system occurs, and when mechanical releasers dump and introduce air into the system. Several studies over nearly a decade have compared sap yields from CV adapters and spouts to various non-CV spouts and adapters.

High Brix Syrup Processing & First Two Seasons with Lapierre HyperBrix

Given our extensive research experience on RO processing and flavor, and the appearance of new RO technology that could concentrate to higher levels, a shift toward this new technology seemed appropriate. Therefore after investigating various options, we entered into a partnership with Lapierre Equipment to utilize the new HyperBrix RO system at UVM PMRC. This paper describes some aspects of our first two seasons of use of this equipment. Given the state of the industry, we define Òhigh brixÓ maple sap processing as RO machines capable of producing concentrate at 30¡Brix or higher.
