I'm running low on glass but I can get a lot of 1x used PET 20oz soda bottles at work.
Since these hold carbonation for soda I'm sure they will for beer for a few months, but what about the caps? Do I just throw the ring away and reuse them? How tight should I tighten them?
Is this a bad idea? I'd really hate to lose beer, but I can drink the plastic bottles first.
