Speaking of new technologies in beer cans, according to New Tech Spy, Miller Brewing will be experimenting with cold can technology for their beer cans sometime mid-next year. Cold can technology is a can that at the push of a button lowers the temperature of the beer inside by 30 degress in about three minutes. Sounds like a gimmick to me, but who knows? Maybe people really will pay more to be able to quickly chill their beer to the point where they can no longer taste it. It can only improve the American-style lager inside.
And you were worried about metallic flavors..Ha!
