I decided to take advantage of the cold weather, and get a lager going in the garage. I bought some old lager yeast on sale, and had to get it going for about 2 days at 60°F before I saw any activity. I put it in the garage last night, expecting to see the temperature fall to 55° By morning. The low last night was 12° here. It's an unheated, attached garage. This morning, the beer temp is 60°, which I think is close to what it was last night when I went to bed. I have the glass carboy fermenter well wrapped with blankets, and I have fermwrap on the carboy, set to come on at 55°. I know fermentation produces heat, but that much? This is my first foray at garage fermentation. What are your experiences? Should I forget about the blankets? I don't want to waste energy, but I do want my temps where I want them.
