Oxygen Barrier Caps - Cold Activated

Oxygen barrier bottle caps have a built in liner that helps prevent oxidation in your bottles. These 26mm caps fit all standard beer bottles, but not twist offs. 

This special cap turns blue when the beer is cold. This way you always know when your beer is properly chilled! The caps start turning blue at 8°C and go maximum blue at 5°C.
