Fermenter's Favorite Oxygen Absorbing Caps 120 count
Fits standard, pry-off beer bottles. Do not use twist-off bottles! These caps have an oxygen-scavenging liner that can help reduce oxidation and staling. 120 per bag.
For best results, do not use an oxidizing cleaner or sanitizer such as One-Step or Easy Clean on caps. Other sanitizers such as Iodophor or Star San work fine. Caps are activated when wet and should only be wet just before or after bottling, do not attempt to store and reuse caps that have been exposed to liquid.
