Ahornsirup
Maple syrup has been made from the sap of bigleaf maple trees. While the sugar concentration is about the same as in "Acer saccharum" (sugar maple), the flavor is somewhat different. Interest in commercially producing syrup from bigleaf maple sap has been limited. Although not traditionally used for syrup production, it takes about 40 volumes of sap to produce 1 volume of maple syrup.
