The potential for warmer spring temperatures during maple season creates concerns about how to keep sap cool. With a grant from the Northern New York Agricultural Development Program, Uihlein Maple Research Forest Director Adam Wild successfully built do-it-yourself (DIY) maple sap chilling systems. Sun Community News reports Wild has published the results of the proof-of-concept project in a freely available “Chilling Maple Sap” informational bulletin and a “How To Build a Maple Sap Chiller” guide.
