about 40 gallons
How much sap does it take to produce one gallon of syrup? It takes about 40-50 gallons of sap to produce one gallon of syrup. Each tap yields an average of 10-20 gallons of sap per season: that yields one quart to 1/2 gallon of syrup per single tap tree. One gallon of pure maple syrup weighs 11 pounds.

Maple sap is on average about 2% sugar. Therefore it takes about 40 gallons of maple sap to make one gallon of maple syrup. A rough way to calculate this is called the "Jones Rule of 86", which states: 86 / sap sugar content (in %) = # of gallons sap required to make 1 gal syrup.
