Coors Light’s “Cold Activated Bottle”

Coors Light’s “Cold Activated Bottle”

Sometimes a picture’s all you need. Check it out below: The bottle on the right is at room temperature. The one on the left is straight out of the fridge. See the difference?

If you’ve ever added beer to the fridge alongside stuff that’s already been chilling for days, you know that feeling the outside of the bottle after just a few minutes in the cooler doesn’t work, as the glass gets cold much more quickly than the beer inside.

Solution: Coors figured out how to put temperature-sensitive ink on its labels. It starts turning blue, says Coors, when the beer inside hits 47 degrees and finishes the process finishes at 43 degrees. Thus, you know at a glance which one’s the cold one without having to open it up and potentially spoil an otherwise perfectly good beer.

Is it a gimmick or a great idea? Well, I’m already starting to wish all beer had this nifty ink on the labels. (Alas, what I was really hoping for in a “cold activated bottle” was one that would chill itself without the fridge. Darn.)

    The label is on the outside of the bottle and will cool faster than the beer.
    It’s a macro light beer which means who cares, it already sucks.
    The tempature range of this new gadget is 48-43. I like mine a bit colder.
    just a marketing tool, for your average tool.

    If you can’t keep track of where your COLD beer is, you may have had too many.
    And if you call this swill water beer, you have no taste anyway.

    I have a high tech device to tell me when a beer is cold. It’s called my hand and I have two of them. If you can’t tell if a beer is cold you must have nerve damage in your hand or be a complete imbecile.

    Jef – You totally missed the point. The exterior of the bottle gets colder faster than the interior. You can’t always tell by touch alone if you have some bottles that have been in an hour and some that have been in overnight… both will be cool to the touch, but the hour-long-in beer won’t be cold inside. That’s the idea.

    Hence RadMan’s point…”The label is on the outside of the bottle and will cool faster than the beer.” It works about as well as using your hand.

    Okay I don’t know who the other guy was claiming all that taste stuff but allow me to weigh my opinion on the matter: I’m not an experienced drinker hell if you told me IPA’s we’re awesome I’d tried them I’m not closed minded BUT I am a country folk and I’ll have you know that when it comes to domestic beer such as coors it doesn’t really get any better than this, I’m not saying it’s the best I’m just saying you’re trashing it as if it was awful it does it’s job it gets you drunk with a good flavor. Now on a side note fuck you man
