Brewed my 3rd batch Saturday. A Belgian Tripel. Higher gravity than my first 2. 24 hrs after pitching, (yesterday) I came home from my sons soccer game to find beer coming out of the air lock, and spilling onto the floor, about a cup and a half worth. My first thought was "Well ****, there goes this batch", thinking it was completely ruined. I did a Google search for "beer coming out of airlock" the first result was from this site. A quick and easy solution was found from a thread started 11 years ago from a member who experienced the same thing. I rigged up my blow off tube as suggested, and all was well with the world. I learned this happens from time to time, and that the beer in fact was not ruined. This morning I decided to come back here to register. I will now be perusing this site on the regular. Thanks for existing, homebrewtalk!
