Description
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.

Ryan W. on Feb 6, 2023
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.
How to get the cap to securely fasten? We’re supposed to purchase a device? Ty
lizabeth fiedler on Nov 23, 2023
BEST ANSWER: Yes, you need a device. I use a two handed capper ( works like a cork remover in reverse) and have had no problems with sealing. Others use a vertical capper.
What size are the caps - 26mm, 29mm, or 31mm? It would helpful to put this in the description
Jonathan M. Goodling on Dec 5, 2023
BEST ANSWER: The caps that I have ordered are 26 mm in diameter and fit perfectly with the 500 milliliter bottles that I also purchased from more beer. I also have some 22 ounce bottles which the caps also fit.
Do these caps fit the ez cap flip top bottles?
Jim Hammer on Sep 28, 2020
BEST ANSWER: No, EZ cap bottles have tops that do not accommodate crown caps.

I suppose they work
To be very honest, I can’t swear these do what they claim, but they don’t make things worse. To really say they work as advertised would require some very expensive lab equipment that maybe only 3 homebrewers in the world have. So I just take it on faith. I certainly can’t taste a difference in beers capped with these versus other caps.

Picture does not reflect actual color
The picture and description are "gold", however they are more "brass" colored than gold.

Does the job
Works great. I usually use a sharpie to write a letter or number on the caps to differentiate my batches, and gold works great for this. Never had a problem with these caps, and they look nice too.

Don't overthink it
When this is on sale, just get it. Holds firm on bottle tops. I use a bench capper for the small amount of experimental beers that I don't keg.
