Gold Oxygen Absorbing Bottle Caps

Gold Oxygen Absorbing Bottle Caps

Please select from the following option(s) to see pricing and availability.

Commercial quality beer bottle caps to keep your brew safe and sound from bottling day until you're ready to enjoy it. You will get a good firm seal that will last through transport, gift giving, and storage with these gold bottle caps. These bottle caps crimp down onto the beer bottle and make a firm seal. They don’t rust or leak and they contain an Oxygen absorbing agent in the liner, which means you won’t get any unwanted oxidation. A good value for a great product.
26 mm diameter caps fit American bottles. Some imported bottles and some sparkling wine bottles use a 29 mm cap instead. We recommend test fitting prior to filling if you're re-using an imported bottle.

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: In addition to the excellent information provided here, I would like to add an excerpt from the patent filed for the oxygen absorbing gasket in beer caps: "In a patent directed to beer packages (Hofeldt and White, 1993a), the developers indicate that the same oxygen absorbers in the same polymeric matrix are activated by thermal pasteurization or sterilization. Although the relative humidity in the headspace of a beverage-containing bottle or can is generally sufficiently high to activate the scavenger, the reaction could be accelerated by heating to increase moisture permeation into the scavenger mix. Thus, they suggest a scavenger that remains effectively inert until pasteurization or sterilization. Moisture generated from the interior contents permeates into and becomes trapped within the gasket to accelerate the oxygen-removal reaction. Oxygen trapped in the headspace and that permeating into the bottle through the gasket are both reacted with the scavenger."

In other words, it is not required to submerge them in water before capping, because the relative humidity inside a capped bottle is sufficiently high to activate the oxygen absorption. In addition, boiling the caps will not destroy the oxygen absorption properties, because they are designed for thermal pasteurization. I would still advise using them right after sanitizing, as others have suggested.

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.
