We always use a blow-off but had our first volcano on an IPA last weekend. Used a stir plate and starter with two smack packs. In hindsight probably over did it on the yeast but was impressive to witness.
I'm currently having a small volcano... Transferred into Carboy with some fruit purée for secondary fermentation... Thing was going nuts so I just split it into two parts >.> still wasted some beer and time
My very first batch was in the basement. The morning after pitching, I was asleep on the second floor when the lid blew so hard that it literally shook the floor above. My ex wife heard/felt it but, unfathomably, did nothing. I discovered it a couple of hours later and couldn't believe she didn't AT LEAST wake me up!
Boooooo,,,, Hisssssss!!! That was nothing, that's what it looks like when things go well for me. I wanted a picture of you mopping the walls.
Yeah, I know. Mine seems pretty minor now compared to others. Never happened to be before, so sort of caught me off guard. I have a feeling though if I didn't check it before I left for work and let out some pressure, it would have been much worse later on.
