I woke up this morning to oatmeal stout all over the dining room (ruined carpet). I had used a carboy to ferment (I normally use my fermenter) but wanted to make two brews this weekend. Overnight the stout blew off the bubbler, foamed over and put a permanent stain on the carpet! Shlitz!! What a mess. I ALWAYS put towels under the brew when I use that location, but not this time!
It would normally have been in my brew closet, which has all my equipment, supplies and fermenter, so nothing can get hurt.
I've never had a brew that active - now it is in a 6-1/2 gallon fermenter, with plenty of room to work.
