That looks much better than having to wear a rainsuit indoors!!
Because of the steam during the cooking process?
Very nice work Tony.
Yes. I think it's something like 30-50 gallons of sap to one gallon of syrup. I think it all depends on the sugar content of the sap.
I made syrup one year just to see how hard it was, and lets just say that if you aren't going to make a bunch of it and sell it, it's cheaper to go buy it. I didn't have to worry about running the humidifier for a while, even with the range hood venting outside from over the stove.
