Brewmaster Mikkel Borg Bjergsø set out to create a series of four beers, one for each station, together with Swedish design studio Bedow. Both the beer and its packaging would interpret the seasons. With a temperature sensitive color and two simple symbols the product mimics the changes between different seasons. When the beer is cold it displays a symbol representing the previous season, but when it is empty, or when a hand grasps the bottle, the heat-sensitive color fades and gives way to a symbol representing the next season. The series is a limited edition of 3500 bottles for each season: Pale Spring Ale, Summer Pilsner, Autumn Porter, and now Wild Winter Ale.
