Both batches of CS that I have brewed had a very active and quick fermentation. The first was my very first batch-I had no temp control, and room temp was probably about 70(so my fermentation was at about 75).made good use of the blowoff tube. Still turned out good.
Second batch is in primary now. I brewed sunday, pitched at 11am at 56F, and had activity during that night. Went all day yesterday with the blowoff tube(definitely needed it) and stopped sometime this afternoon. Beer temp was at 62 or lower during this entire time. So I only had about 36 hours or so of what I would call very active fermentation. So even with the temp control, my observable activity didn’t change much-short and sweet. What I do expect to change, though, is the quality of the beer.
This is my eleventh brew and I still feel like a total newbie. But with the help of all these fine folks, I’ve been able to make some pretty good beer. So Drox, leave that sucker in the primary a few weeks longer I’m sure it’ll be fine–and welcome to the most fun you can have with your underwear still on!
