Yesterday I brewed up a batch of an american brown ale. 24 hours after pitching, it doesn't to look to be moving so well. There are hints of a krausen, but not as much as there should be. I don't see any of the nice churning that there should be. There really is no airlock activity (although I have quite a bit of head space, doing a half batch into a 5 gallon carboy) Here is my plan, let me know if I am thinking the wrong things:

Currently the temp is about 65, I was going to let it warm up a few degrees and see if I get some more activity by this evening. If not, I was going to re-hydrate some more S-05 and throw that in there. I was not going to re-aerate it, as there is a small krausen, meaning I probably should add oxygen at this point.

I'd leave it overnight and give it more chance to work. Just because there is no activity in the airlock does not mean it's not fermenting

  • Agreed. I have had some beers take 48 hours before activity was noticeable in the airlock. And that's with a full 5 gallon batch. Commented Dec 2, 2012 at 23:49
