I have a beer I just pitched last night and I woke up this morning to hissing coming out the sides of the bucket and the lid is noticeably bulging. I put it out side to try and cool the temps down (it must be over 70), and so if the airlock blows out I don't get beer all over my house. Not really sure what to do, I don't want the beer to explode all over the house and I don't want to chill the yeast and stall the process? Any suggestions.
