So I brewed my first batch this past Sunday. I made the Irish Red that came with my starter kit. I pitched my yeast (Danstar Nottingham) directly into the fermenter at 78deg F. I put my S-shaped airlock on and put it in my basement. Seeing no activity the first 24 hours i took the top off real quick to take a peek inside and there was a good 1 inch of foam at the top so something was going on in there.
I decided to switch to a 3-peice airlock and after doing so it finally started to bubble a bit (about one bubble every 5 seconds). Not sure why the S-shaped airlock wasn’t bubbling. I checked it again about 4 hours later and all activity had stopped. It’s not even 48 hours later and I see no activity in the airlock.
Should I be concerned? Should I take any sort of action?
