For those of you who use better bottles as a fermenter, here's a cheap & easy cap for a blow off assembly. It's just the cap off one of those big blue water jugs from the grocery store. They come with a hole in them, and fit a 3/4" hose perfectly!

Great idea. Thanks. Are the better bottles made of the same material as the office / grocery store water bottles?

Answered my own question: No; at least not the ones we have at our office. They are #7 bottles and I believe the better bottles are #1. Oxygen permeability may be worse in the non better bottles.
