Our Kellerbier is based on the oldest known recipe at ABK, dating back to 1308. Kellerbier translates to 'cellar beer', an obvious reference to the cooler temperatures the beer is brewed and conditioned under. Lacking any type of refrigeration technology, brewer's would brew their beer during the cool months of the year and then lager them in caves. These caves acted like natural cellars allowing the beer to remain at a stable, cool temperature for the length of their slow maturation. Naturally cloudy and unfiltered, a delicious tasty beer.
