When does spring start? Does it start when the chickadees change their call? Does it start when the red-winged blackbirds return to the Lynch Wetland? Or does it start with the first harvest of the year?
A small snap of warm weather this year in mid February, combined with the enthusiasm of my colleagues Gabe and Syd, sent us into the forest. Vecny Woods has a ravine full of old sugar maples.
The sap from a sugar maple is usually 2%-3% percent sugar, and we set 26 taps in the Vecny Woods sugar maples. We will also be tapping silver maples in the floodplain (77) and box elders (a handful) in the former barnyard of the Penningroth Barn. While all three types of maple trees provide good sap, the silver maple sap has a sugar content of 1.5%-1.75% and the box elders have 1% sugar content. That sap requires longer boiling time, which in turn makes a darker syrup with a more robust flavor.
Reducing that sap to syrup requires a lot of firewood, a lot of boiling, and a lot of steam. It also requires a lot of patience. While the sap was flowing on February 11, our night time temperatures have been hovering around freezing, and the days have been cloudy. Those are not conducive to sap flow, and the trees have just been trickling. We might have enough to make three gallons of syrup. Fortunately, sap season has only just started, leaving us with a good month left for the weather to start cooperating. Next week is looking promising.
