These oxygen absorbing bottle caps protect your bottled beer from the staling effect of oxidation. Oxygen that remains in the head-space of your bottled beer is absorbed by the lining of these caps, thus prolonging the shelf life of your beer. These oxygen absorbing caps are also recommended for beers that require long term aging / bottle conditioning.
