Full Answer

Farmers tap the trees by boring holes into the tree trunks and inserting spiles that funnel sap into a collecting bucket. They boil the sap and concentrate it to produce maple syrup. The sap-collecting season lasts from four to eight weeks, with peak flow lasting only about three to four weeks. The average tree yields about 9 to 13 gallons per season. The best maple trees to tap are 30- to 40-year-old sugar maples, silver maples, red maples, black maples and box elder trees.
