Massive blowoff!

I'm not sure what happened with that last batch of Panama Red. It ended up a little short on volume, so there is a lot of head space in the fermenters. Still, the yeast managed to work itself up and out of the air lock. Not a huge mess or anything, but still. The only time I've had blowoff like this was with that batch of weiss beer last summer, and that is to be expected with a weiss.
