Oxygen Barrier Beer Bottle Caps - Cold Activated (Approx. 100)

These high quality German made & oxygen lined bottle caps fit any standard pry-off beer bottle.

Cold Activated Oxygen Barrier bottle caps help keep your beer tasting fresher for longer!

This style of bottle caps have a beer glass icon and require a bottle capper to properly attach.

These bottle caps are fun, inexpensive, a bit out of the ordinary and a good way to start a conversation about your homebrew.

They begin to change to a blue colour at approximately 45 degrees, and will reach a "maximum blue tonality indication" at 41 degrees. What does it mean? When the cap is blue, you've got cold brew.
