Oxygen Absorbing Yellow Beer Bottle Caps These metal crown caps are made for standard 26mm pry-off beer bottles and come in a pack of 144. They’re a good choice for sealing your homebrew—whether it’s beer, cider, or another carbonated beverage. The pry-off design gives a tight, reliable seal that helps lock in carbonation while keeping oxygen and contaminants out. Easy to notate, you can write on top of the lid or label your bottles however you like. The interior features an oxygen-absorbing liner to help preserve the flavor and shelf life of your batch. These caps are compatible with most manual and automatic bottle cappers. Just make sure not to use them on twist-off bottles.
