I brewed 5 gallons of Patersbier on Nov 10th and had brewed it once before using only an airlock, so I figured it wouldn't be a problem this time, either.
Last night I looked at the fermentation and it was quite active but seemed OK. Well, this morning I went to the basement and...oh my. The airlock was still intact but it was plugged tight and the cap was bulging. I quickly grabbed a blow off tube and stuck it in a 5 gallon bucket of StarSan. Then I ever so slowly tried removing the airlock, but still ended up with a face full of yeasties and it splattered the ceiling, as well.
I got the blow off tube attached, but it continued belching krausen through the blow off tube and into the container for a half hour.
This was the first time (hopefully the last) this has happened to me. Did I do the correct thing or should I have done something else, other than put the blow off tube on first?
From now on, everthing gets a blow off tube...
