All About the Cornell Maple Program (CMP)

Our Mission

Pure maple syrup is a traditional natural product unique to North America. The Cornell Sugar Maple Program exists to improve the production and use of maple products by working with producers, consumers, and others interested in this fascinating local product. This website supports that goal by providing:

  • Maple syrup production information for the general public, syrup producers of all skill levels and educators
  • Information on maple activities including workshops and conferences
  • Information on extension and research projects
  • This section includes articles that were either written by, or that feature the Cornell Maple Program, published in various Maple and other news outlets.

    • Maple Sap Concentration Processes and Variable Cost of Different Fuels Worksheet:
      Basic Instructions for using this downloadable file: This spreadsheet template was created by Chuck Winship, maple producer in Livingston County NY, as a practical guide to compare the energy costs of various pieces and combinations of pieces of maple sap processing equipment. To use this spreadsheet you must have the Microsoft Excel program already on your computer. The accuracy resulting from using this program is completely dependent on the information you provide the program. The information contained inside the black boxes is variable with different pieces of equipment, individual setups, production volume and fuel sources. Use the best information available to you to place correct numbers in these boxes for your situation. Keep in mind that this program is only comparing energy costs. Other costs associated with changes in labor, capital investment, quality changes or maintenance cost are not considered here but are an important part of any equipment purchase decision.
