The stout I have currently in the primary fermenter was showing a lot of activity and CO2 production from the air lock. Unfortunately I didn't think that the brew was going to need any extra care during the primary fermentation, but that wasn't the case. I checked in on the beer during day two and found the air lock clogged and beer on the top of the outside of the fermenter. A little foam block and we're back in business!
The only problem I am having now is.....where to put all the beer!
