Description

These Oxygen Absorbing beer bottle caps have a special liner that absorbs oxygen in the bottle's head space. This helps reduce the oxidation that happens during the bottling process, keeps your home brewed beer tasting fresher, and can extend it's shelf life.

Important to note: It is recommended that you only sanitize as many caps as you'll require at the time of bottling. The oxygen-absorbing agent is activated when the cap gets wet. If wetted caps are saved for later use, they'll still function as a normal cap, but the oxygen absorbing agent may be depleted.

If you sanitize these with Star-San right before capping (say 5-15 minutes) does the oxygen absorbing still work? Or do you have to use them unsanitized? And do you no longer carry non-oxygen-absorbing bottle caps?
Roy Westerberg on Jan 22, 2018
BEST ANSWER: The oxygen-absorbing compounds are activated by water/sanitizer, but contrary to what a lot of people assume, they do not get "used up" immediately after activation. The caps are designed to absorb oxygen slowly over the next day or two after being activated.

So yes, you should sanitize these like any other bottle caps (5-15 minutes should not make a difference in their effectiveness), just don't sanitize them and then leave them around for days before bottling.

works perfectly on the 500ml sour bottles
Recommend this product, they are oxygen absorbing caps, will last a long time. I have also done the Cantillon style cork & capping with these as well and they work.

Provided a good seal
I just bottled my first batch with these caps. They went on securely and believe I will not have any issues. The price is right, mostly for the oxygen absorbing caps.

Too small
I've ordered the same product over the years and not had any problems until recently. They will not fit all long neck bottles, and do not play well with the short, Sierra Nevada style bottles. The bag says they're 26mm. I've had much better luck with the 26.5mm caps.

Does not fit well on standard bottles
These caps seem too small for standard bottles. Bad fit led to 2/5 of my batch losing carbonation. Will not buy again.
