Description: Bigleaf maple sap flow during the 1970-71 season ranged from none to 16.9 gallons per taphole and sugar content of the sap from 1.0 to 2.6 percent. Sugar content also varied seasonally, with the sweetest sap flowing in late January. The sirup was very flavorful, although not as strong in typical maple flavor as that made from eastern sugar maple. Sirup production appears quite feasible as hobby. The possibility of commercial production should not be ruled out as traditional local experience is gained.

Keywords: Maple sugar, bigleaf maple, Acer macrophyllum, sap
