On friday of last week I brewed an IPA with california V yeast. As of about thursday of this week I thought I had done something wrong because there were no signs of fermentation. Then tonight I wake up hearing a bang and what do you know, it my BEER! The beer is fermenting outside in the garage inside of my brew fridge, and I can hear it in my bedroom? Has anyone encountered this? I have never heard/ seen so much action 5 days after a brew session?
