We know, beer bottles with colour-changing mountains are kind of lame, but Danish brewery, Mikkeller, has taken the idea and made it so much cooler.
Mikkeller recently released four seasonal beers: one for spring, summer, fall and winter. First, brewing a beer for each season is the best idea ever. (Hey, its one good reason to drink an ice cold beer in the dead of winter.) But Mikkeller also printed the labels of their seasonal beer bottles, which were designed by the Bedow graphic design studio, with heat sensitive ink that turns the snowflake on the label into a sun when it gets warm.
