Sap Pricing

This tool 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."

Based upon a spreadsheet originally constructed by Dr. Michael Farrell, Cornell Maple Program and adapted by Dr. Tim Perkins, UVM Proctor Maple Research Center

The "split" (proportion paid to the seller) should be agreed upon by both the seller and buyer ahead of time based upon the prevailing market, delivery or pickup, and sap quality considerations.
Sellers and buyers should agree prior to sale which source for bulk price will be used, including any premiums (barrel, organic, volume, delivery) or deductions (pails, defects, transportation, unfiltered) that are applicable.
Seller and buyer should both measure sap sugar content with temperature-compensated and calibrated refractometers or sap hydrometers, or agree on a method.
Seller and buyer should agree upon a standard method of determining sap or concentrate volume.
Include Syrup Weight Adjustment
No: You choose to calculate the results based on syrup weight that represents a "pure" sucrose solution (11.027 lbs/gal @ 66.0 Brix, 11.053 lbs/gal @ 66.5 Brix, or 11.073 lbs/gal @ 66.9 Brix)
Yes: You choose to round down to 11 lbs/gal which adjusts for materials other than sucrose that sap contains and the liquid loss ("shrinkage") that occurs in each transfer or processing step.
