Doppelbocks vary from amber to dark brown in color and range in alcohol from 7.5-9.5%. This is a sub-category of the bock style. These beers are extra strong, rich and weighty lagers characterized by an intense malty sweetness, with a note of hop bitterness to balance the flavor. Doppelbocks were first brewed by the Paulaner monks in Munich. At the time, it was intended to be consumed as "liquid bread" during Lent. Noteworthy examples of this style include: Ayinger Celebrator Doppelbock, Paulaner Salvator Doppel Bock and Capital Autumnal Fire.
