You know you have an issue when you go out to your car in the morning to go to work and see beer seeping out from underneath the garage door. This looked much worse this morning before all of the foam collapsed. I should have taken a picture then.
Most of the time I have pretty good luck, but this is the second time this has happened now. I've ordered a new fermenter but I won't have it until early 2011. It will have a little more headspace in it and I'll actually be able to direct the blow-off into a bucket.
