Oxygen Barrier Bottle Caps (Blue)

(1 review) Write a Review


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.

    Avoid these caps

    Posted by Unknown on 27th Dec 2015

    Prior to these caps, I had been using generic gold caps that are locally available. On a whim I decided to purchase these based on the phrase "oxygen barrier." I had never had issues with oxidizing in my beers, so I think I was more attracted to the color than anything. These caps turned two back to back batches from a beautiful orange haze, to brown sludge within weeks. I have never had this issue in my entire history brewing and bottle conditioning beer. These caps are the only new factors with those batches, and have not had any problems since switching back to the generic golden boys. I have to bet that these caps were the culprit and I just wanted to let others know. I would be interested to hear if anyone had a similar experience with these.
