I have a 12 Gallon brew pot and tried my first all grain with a brew sack. I started with about 7 gallons water. heater water to initial temp of 165 and mixed in the grain and shut off heat and put on the lid and insulation. I removed lid and checked temp which was about 150. The flame was restarted somehow left on low but additional heat got up to around 195-200 at about 50 minutes. I shut off the heat and drained and sparked for about 10 minutes. I then proceeded to the boil and ended with about 6 gallons of London Porter. Is there any chance it's drinkable? I probably could have used some adult supervision but that's what happened.
