On average, a single tap produces 10 to 20 gallons of sap per season, depending on factors like the tree’s size, health, weather conditions, and length of the sap run. Since it takes roughly 40 gallons of sap to produce 1 gallon of maple syrup, this means: • 10 gallons of sap = 1 quart • 20 gallons of sap = 1/2 gallon of syrup So, one tap typically yields 1/4 to 1/2 gallon of maple syrup per season. | The Maple Farmer
