Doppelbock literally means "double bock." It is more extreme than a regular bock, but not twice so, with alcohol levels between 7 and 8 percent by volume. Its roots go back to the Paulaner branch of the Benedictine order of monks who were resident friars of the Dukes of Bavaria. Having witnessed strong beer-making in the noble brew houses, they tried their hands at the brew themselves, and soon this new and strong liquid bread became the obvious meal of choice for their frequent fasts.
The doppelbock is a strong, very malty German lager with appreciable alcohol, sweetness, and malt-driven flavors and aromas. Brewed correctly, this beer is an easy-drinker "brewed for holy nourishment," but it is often overdone, which can make it overly big and alcoholic, so avoid that if you can.
