144 Cold Activated Bottle Caps with Oxygen Barrier

You've seen thermochromatic cans and labels on commercial beers for a while. Now homebrewers can top their brews with a cap that will turn blue when the beer is cold enough to drink. Seriously, how cool is that??

These will fit standard crown cap beer bottles. These will not work with twist off bottles or Belgian style bottles.

4 Stars
Changes pretty quick
Caps do as they say - color change to a dark blue when they are cold. Changes pretty quick back and forth too. I give it four stars though because they rust really really easily. The inside and outside tops are okay so the beer should be fine, but it's not pretty to see rust on the edges of the beer cap.
