Still slow here, I boiled two weekends ago, had 130l sap and finished 3.5l syrup. Over the last two weeks I only gathered 100l of sap. Second boil today, but first I had to thaw the blocks since I have been storing it in the freezer.
I sure expected more sap so far from my 40 taps, fortunately the weather this week looks promising. Still 2 feet of snow in the bush.
2018: 40 taps, 19.5l syrup
2017: 80 taps, 20 liters syrup.
2016: 40 taps, 38.5 liters maple syrup. Bonus 1 liter of Birch Syrup from 12 taps.
2015: 1st time! 13 taps, 175l sap, 8.2l syrup
Boiling on arch made from old wood furnace with 4 steam table pans
