Most commonly used to refer to a very strong, German-style lager beer. To be called a Doppelbock under German law, a beer must have an original gravity of at least 18 P (specific gravity of 1.072). Most Doppelbocks have names ending in -otor, in the tradition of Paulaner Savator, which is widely acknowledged to be the "original" Doppelbock. The term Doppelbock can be also be used as a designation of strength, as with Schneider Aventinues (a Wheat Doppelbock Ale, or Weizen Doppelbock).
