I've tried this method (
HBT Cheap beer gun) a few times, with alright results.
I took some to my buddy a few weeks ago and he mentioned that the two he drank after two weeks were flat.
I'd like to pull 6-12 bottles off each batch, so I'm thinking I might pull the trigger on the Blichman unit soon. Worth it, eh? OBK has them for $75 and the accessory kit is $25. NG has them for $90 but don't seem to carry the accessory kit. Is it something I can easily piece together with common parts? Doesn't look too complicated.
