Called it quits last night. Sap was running strong when I pulled the plug. I think the trees ran out of sugar. less than 1%. The sap became too nasty for me to want to handle. The days are just too warm to keep sap in good condition. If it was all about making sap then I could see going another week. I am very happy with the season. I made 1,825 gallons. just shy of 1/2 gallon per tap on my trees. The rest was purchased sap. I will be January tapping from now on.
