Maple Days Gary Graham

Ohio Maple Days 2016

Gary Graham, OSU Extension, compares a producer’s hydrometer to a master hydrometer — used to measure the density of sap collected — at Ohio Maple Days, Jan. 22 in Fredericksburg, Ohio. Graham offers this as a free service to producers who attend the Maple Days workshops.
