I didn't know if anyone else wants to share information about their syruping year, but thought I would post how mine turned out. I tap in NE Minnesota. This year has been my absolute worst year. Here are some numbers.
Total taps: 225
Total Sap: 492 gallons
Total Syrup: 9.14 gallons
I have 50 taps on 3/16 nat vac which gave me 285 gallons or 58% of my sap. The remaining 175 taps gave me 207 gallons. That comes out to 5.7 gal/tap with nat vac tubing and 1.18 gal/tap on bags. Natural vac out-performed the bags 4.83:1 which saved my year. I collected 3 times and boiled 2 times. Needless to say, on the upside, I have a lot of wood and glass bottles left.
Anyone else care to share? I know some have had banner years depending your location and the weather in your part of the state.
