Breathable beer bottle cap

A company in the United States is concerned about the fear of oxidation of beer, the general phenomenon that the oxygen in the beer bottles will be degraded, and the development of a beer bottle cap with oxygen absorption function can slow the beer oxidation process. It turned out that in this kind of oxygen-absorbable beer cap, a compound liner that can absorb oxygen is embedded. Through the small holes in the liner, the oxygen in the top void of the beer bottle can be absorbed. It is said that the use of this kind of beer bottle that can absorb oxygen can extend the beer shelf life of 2-3 months.
