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.
Turns blue when they’re cold as advertised.
I purchased several items that a family member needs for his home brewing. I know he’ll love the bottle caps, bottle drain system, & cleaning brush!
Well it's pretty clear to tell when it's cold enough to drink and it was a fun addition to the bottles
These are the perfect touch for keeping my impatient tendencies at bay.
