Cold Activated Crown Caps with Oxy-Liner - 120 Count
These bottle caps are perfect for brewers afflicted with tactile hyposensitivity, or anyone who ever thought, "This beer feels cold, but it doesn look cold." Take the guesswork out of chilling your homebrew with these amazing cold-activated crown caps. They begin to change to a blue color at approx. 46 degrees, and reach "maximum blue tonality indication" at 41 degrees.
What does that mean? If the cap is blue, you've got cold brew. They're fun, inexpensive, a little out of the ordinary, and a good way to start a conversation about your homebrew.
Love em Classy bottling look
They keep the beer carbonated so what else can I say?
Capped my Cream Ale with these. Nice addition.
The cap does get blue, and really blue if you get it really cold. They are fun to have and a good alternative to the generic silver and gold caps.
These work just as well as any other bottle cap. What is my favorite feature on this product is the cold activated, ready to drink, notification signal it turnes dark blue. I get quite the reaction when I hand a buddy a home brew and mention the cold activated cap. It’s a nice little novelty. If you’re going to take all this time to make your masterpiece brew why not (TOP IT OFF) with some Cold Activated Crown Caps! Get yours today! Cheers -Mike
