Bottle Caps - Cold Activated



Package of 48 Oxygen Barrier Cold Activated Caps

Unique bottle caps are ideal for keeping your homebrew organized!  Cold activated caps start to turn a light, icy blue around 46.4° F and become very blue at and below 41° F!  If you've ever wanted a blatant indication of the temperature of your homebrew, and even a handy 'Ready to Drink' label on your cap, this is it!  

These caps are 26 mm and fit all standard size 12 and 22 oz bottles, as well as Vichy bottles and EZ Cap Brand Flip Top Bottles.
