Got home at 4pm today to find the Tanks overflowing, vaccum at 24" still, got 550 plus gallons since noontime Sunday. Still flowing good right now, made 5 gallons Dark Robust tonight , sugar content at 1.2, I really need an RO for next year. Going to try and make it to the weekend, it's 37 now at my house, just took a ride to town and it was nearly 50°. So hopefully I can hold onto that cold air.
