How many ounces of maple sap are in one gallon of maple syrup?
Depending on the sweetness of the sap, it can take anywhere from 25-75 gallons of raw sap to make a gallon of finished syrup. The usual amount is about 40 gallons of sap to one gallon of syrup. Each tap into a tree will yield about 10 gallons of slightly sweet sap over a period of the 4-5 week sugaring season. This 10 gallons of sap, when boiled down, will yield approximately one quart of finished maple syrup.
