The 64 ounce (2000mL) Ball Lock Keg is the smallest Cornelius keg lid capable ball lock keg to date. Primarily designed for a compact carbonating reservoir for soda water systems, with the addition of the KegLand Continuous Soda Carbonator Keg Lid. It can of course be used as a more homebrew-styled portable party keg growler.

This little guy also works great as a line cleaning keg using a small batch of cleaning solution.
