Description
The finishing touch! Make these Oxygen Absorbing Bottle Caps your last line of defense against oxidation and eliminate your worry.
 
These Oxygen Absorbing caps have a special liner that absorbs oxygen in the bottles headspace. 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: These caps activate once you get them wet. Do not wet or sanitize caps in advance of your bottling session or they will not work correctly. They’ll still close the bottle like any other cap, but the oxygen-absorbing function will be used up.

Can these be used on twist-off (screw-top) bottles?
Marc Guay on May 24, 2022
BEST ANSWER: No. These will only work with pry-off style bottles. They cannot seal around the screw threads on the screw top bottles.

Great Bottle Caps
These are my standard cap. No issues, solid choice.

Beware, carbonation suffers
Two weeks after priming and bottling, the bottles using these caps contain completely flat beer. Flip cap bottles are fine.

Bottle cap
Works great as a bottle cap, not sure if the oxy absorption makes any different (have read people swear by them). Had to try them, and they worked as a bottle cap.

Ideal for bigger beers and aging.
Prevents oxidation and off flavors, sealing in more ideal traits. My homebrew with these caps are slightly better. Remember, IPA's and anything under 7%abv will not keep long or age well. Author Joshua Bernstein has great advice on beer aging.

Perfect
Great for absorbing the 02 in the head-space of your freshly bottle brews!

These caps probably make your beer better.
I haven't tested these Oxygen Absorbing Bottle Caps against regular caps, but they probably prevent beer that's been sitting around too long from tasting stale. Why not give your beer it's best shot at tasting great. Plus, they're shiny.

Work Great

Good caps
I like these because they absorb oxygen when wet and are inexpensive. I label my beer by writing on the caps with a industrial sharpie.

highly recommend
I only use oxygen absorbing caps when I bottle. Why chance it? Ive never had a problem with oxidation in 16+ batches so far. Every beer has tasted fresh as can be.

Worth It!
I was a bit doubtful about whether these caps would really change much, but figured I would give them a try. I liked the fact that they had the thicker inner seal as mentioned by a reviewer above. Also, we have found since using these that the incidence of having a slight estery or metallic smell that we would occasionally get when opening a bottle (even though the beer tasted fine) has really reduced.
