Blue Oxygen Absorbing Bottle Caps

Blue 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 blue 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.

Dark Blue Crown Caps
These are nice, Dark Blue, crown caps. They work just as expected. It is nice to have an assortment of colors available to help me keep my bottled beers, ciders, and sodas identified without resorting to some kind of sticky labels. They really look nice atop the Cobalt Blue EZ Cap bottles. (Now, if only someone would start selling multi-colored gaskets for the swing-top closures in blue in addition to red).

Order came very quick!
Caps were a slightly scuffed but it worked to my advantage for what I was using them for. That may understandably be a drawback for some.
