Köstritzer Schwarzbier

Köstritzer Schwarzbier is one of the most famous and historically significant dark beers in Germany. Originating from Bad Köstriz, Thuringia, the brewery has been producing this specialty since 1543, making it one of the oldest manufacturers of schwarzbier in the country. The beer is characterized by its deep black color and roasted malt flavors, which are achieved through a traditional brewing process that complies with the German Reinheitsgebot (Purity Law).

Today, the brand belongs to the Bitburger Braugruppe, a large family-owned German beverage group. While the ownership has transitioned to a larger corporate structure to facilitate international distribution, the production remains centralized in Germany to maintain its authentic regional profile. The Bitburger Group oversees the global marketing and ensures that Köstritzer remains a leader in the dark beer segment worldwide.
