Other options for 2 L. plastic bottles than just soda bottles?
 

I'm curious if anyone has found any cool or interesting 2 L. or 1.5 Liter plastic bottles in place of standard 2 L. soda plastic bottles for use with a carbonator cap.

I bought a 2 liter of kvas that is no different from a regular bottle, except it's brown. If I can get rid of the kvas taste, it could make a good growler.
