I did some searching for this, but using words like "temperature" & "fermentation", etc. brings up just about every thread in this forum
Anyway, we don't have a fermentation chamber yet (scouring for one now) and my basement is warmer than I ever remember with this brutal summer.
Right now it's 69 down there, and the ale pale temp is showing 72 and so is the tub water the fermenter is sitting in.
For our next brew I plan on using frozen water bottles and a fan to go along with the tub water and t-shirt already in use.
My question is how long do I really have to worry about keeping the temps in the 60's? We normally do 3 week primaries and then bottle. Is it OK to to just keep changing out the frozen bottles for the first 3-5 days while the vigorous fermentation is happening and then not worry about it as much? I'm not talking about 80 degree temps or anything, my basement should never get above 70.
I was thinking about ice bottles in water for the first 4-5 days, then just water and fan until the 2 week mark, then maybe letting it sit on the concrete floor for the last week.
Sound good? I can do the frozen bottle switch longer if I have to, I was just hoping to not have to keep it up for 3 weeks straight.
thanks for your help
