I brewed a batch and had it bubbling away. Then it slowed down until at about day 8 it was stopped. This seemed normal and fine. Then at about day 17 it started to bubble, like one burp every 5 to 10 seconds. Now at day 18 its still burping.
Id had it at 62 to 66 degrees. I noticed it crept up to 70 degrees at the re-birth. I think the temp increase is due to my inattentiveness, not heat generation, but I m not sure.
Is this temperature related or just coincidental, it the beer ruined, what to do?
