Starting to get warm here in Vegas so I'm trying to dial in a method of keeping fermenations temps under control (w/o having to buy any additional supplies) so I can continue to brew into summer.
1st day didnt have much activity so I was sitting at a nice 68*. 2nd day, things took off and reached around 75* so I wrapped with a towel and a put a big fan on it and managed to get it down to around 73*. For whatever reason, it got hotter the following morning.. up to 80*. Decided to now give the bath tub method a try, and damn, it works really good.. too good..lol Put it in the water and got it down to 68* again so all was well. But I guess overnight with the cooler temps it dropped way down to 64*... dammit. So this morning I took the water out of the tub to let it warm up again and hoping by the time I get home it'll be back up to around 68-70.
Keeping a stable temp has been one hell of a challenge.. starting to think I'm going to make a styrofoam lid for my cooler.
fwiw.. the temp range for the yeast is 63-76. The yeast were slow to take off so i'm hoping i didn't stall them with the cold temps or cause any off flavors from the high ferm temps.
