I recently went to Köln, and I really liked the small kegs they use to serve Kölsch. The pittermännchen (sometimes called party kegs, party Fass, party barrels, Kölsch Fass, etc) typically come in 10-30 liter sizes. I would really like to have a 10L one, but they're extremely difficult to find. Does anyone have one of these kegs and/or know where you might be able to get one? Thanks!
