Hmm, Far as kegs go, the water tower barrel for the fire brigade is done well. I will have to drag up some pics for ya.
Or the instructions may on lego.com. It's two crow nest containers you find on the pirate ships with a 4x4 base to 2x2 top cone with an axle through it and an upside down container then a brown 4x4 disc on top.
Using trans colored 1x2 rounds with matching gems on top make good looking alcohol containers.
Only a M:Tron can fix something that isn't broke!
