Is there some sort of device that can tell you roughly what temperature your beer bottle is? Something like those strips you can use on your forehead to check if you have a fever but with a temerature range of about 4 - 14 C maybe?
A few bottled beers actually have this built into their labels (Zywiec for example). Though it doesn't tell the temperature, just whether the beer is cold or not.
