Green Oxygen Absorbing Bottle Caps

Green Oxygen Absorbing Bottle Caps

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

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.

Good caps, no leakers
If you're a bottling neanderthal like me, you can never have too many caps on hand.

It's not easy being green - unless your a bottle cap. Helps identify beer.
