8. Oxygen Absorbing Bottle Caps or Not?
Oxygen absorbing bottle caps are a popular item, but are they really needed? Unless you are planning to store your beer for an extended period (a year or more), the answer is most likely no.
The oxygen in the headspace of the bottle during bottling is consumed in part by fermentation of the priming sugar. In addition, CO2 is produced during fermentation of the priming sugar that helps protect the beer.
As long as the caps are tight and properly sealed, there should be little risk of oxidization.
