Got an unexpected run of sap. There was a cold north wind and no sun, but the trees ran well yesterday. Ended up collecting 400 gallons of sap. Sunny days, freezing night? Well, its March and the trees do what they want. Boiled until 9:00 pm last night. Then back over at 3:30 am to boil more and hopefully finish off the batch. Its forecast to get down to 10 degrees tonight so the sap will freeze if left in the tank. Bottled 24 quarts just today for a total of about 90 quarts, 22 1/2 gallons of finished syrup now.
