Ever wonder if your craft brew is ready to drink? Now you can eliminate the guess work with our cold activated bottle caps! When the beer is at room temperature, the caps are white with a tall glass of beer in the center. Once chilled, these caps turn blue-grey, the beer sports a frothy head of suds and the words “”Ready to Drink”” appear!
