Cold Activated Oxygen Barrier Bottle Caps (144ct)

144ct

You've seen thermochromatic cans and labels on commercial beers for a while. Now homebrewers can top their brews with a cap that will turn blue when the beer is cold enough to drink. Seriously, how cool is that??

Oxybarrier is a higher end PVC free liner which totally seals off the bottle. This means, what's in it stays in and nothing comes in or out; leaving the beer fresh for about 3 months longer than a regular PVC free liner. This liner is commonly used for lower rotation, high end beers which are bottled in a near perfect environment. In a nutshell, if you have a good filler and the oxygen is near 0 when the cap goes on, then this liner is the best of the best.
