3 Saturdays ago Todd and I went back out for our first boil. We had 7 gallons of sap that first week and boiled it down outside on a wood fire. It did take on a smoke flavor from the fire. The 7 gallons yielded 16oz of syrup in that first run.
2 Saturdays ago the weather was too cold and there was not enough sap to boil. Last Saturday was warm enough but there was too much rain to boil outside. I took 10 gallons of sap home with the intention of boiling it outside on my wood burning stove outside. It was too late on Saturday to set everything up so I just put a 5-gallon pot on the stove to cook down. The weather took a cold turn on Sunday so I decided to do all the work on the stove.
My large cookpot holds 5 gallons and is 9" deep. Once it gets up to temperature on my stove the big pot boils water off at a rate of 1" per hour. I boiled it down in the big pot until there was about 2" left. I then transferred it to a 1-gallon pot to finish it. The 1-gallon pot is 4" deep and boils down at a rate of 1" in 45 minutes. Once the 1-gallon pot got down to 1" the sap has become syrup.
