Oxygen Absorbing Bottle Caps - 50 pieces

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. 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.
