Ok, what I'd like to know is this: Say you are homebrewing and you buy presealed vials (to ensure they are sterile, then just cut off tops and replace stopper/crimp)a crimper, crimp flip-tops, and butyl rubber stoppers. How do you sterilize the rubber stoppers? i dont want to sound stupid by thinking 'you don't sterilize them', although i could be wrong maybe you dont, but if you do have to, how should it be done? immerse them in isopropyl alcohol? SRY to any of you out there that already 'know' this, just remember the only stupid question is the one that isnt asked. Thx guys
