I boiled inside today. Having two pans going on the stove for most of the day, we processed about 12 gallons of sap. The jar on the right is the result of these two watched pots. It's much darker than either of the first two boils. But that was expected as the sap was collected during the warm spell. Now to see if the colder weather will result in lighter syrup again. It happens.
Also note the precipitate. The left hand jar is the oldest; more settled. The middle was produced this past weekend, and as mentioned before the right hand jar is from today. When this picture was taken the precipitate was just starting to fall out of solution.
