For my one-gallon brethren: How many of you utilize airlocks with your brews, and how many go the blow-off route? I'm going to buy my first set of gear this afternoon, and while price isn't necessarily an issue, storage space is. Neither airlocks or blow-off tubes are exactly massive, but I'd like to have to store as little as possible.
On a related note - are there particular recipes or styles that are known to be more...
energetic than others in regards to fermentation? I'm curious if there's anything I should be on the lookout for as far as possible clean-up suprises go.
