Conditions must have been perfect on Thursday. When I went out into the woods on Friday morning the sap sacs were bulging heavily on the trees. The task of emptying and hauling the sap back to the house became quite a chore. Equally problematic was finding enough containers to hold it all after it had been briefly boiled to stabilize it.
The take for that single day was 9.75 gallons. That's more than 1 1/2 gallons per tree! That one-day flow beats the previous best day by a mile and represents roughly one-third of our total sap collection for the season thus far.
I now have every large pot and container in the house full of frozen sap and Janet is just about fed up with not being able to use any of her cooking pots. Saturday morning we are going to fire up the woodstove evaporator and start boiling down the accumulated 21 gallons. If all goes well we should end up with three times the syrup that our last run yielded.
