Bocks--you know, those beers with goats on the label--are relatively strong German lagers. Doppelbocks--as the name might suggest--are typically even stronger and contain enough malty goodness that theyve been considered a meal in a glass for centuries. Generally they have a very full-bodied flavor and are darker than their little Bock brothers and sisters and a higher level of alcohol too. They range in color from dark amber to nearly black, and dark versions often have slight chocolate or roasted characters.
