A strong lager of German origin with several sub-styles.

The style known now as bock was originally a dark, malty, lightly hopped ale first brewed in the 14th century by German brewers in the Hanseatic town of Einbeck. This style was later adopted by Munich brewers in the 17th century and adapted to the new lager style of brewing.

Traditional bock is a sweet, relatively strong (6.3%–7.2% abv), lightly hopped lager. The colour can range from light copper to brown, with a bountiful and persistent off-white head. The aroma should be malty and toasty, possibly with hints of alcohol, but no detectable hops or fruitiness. The taste is rich and toasty, sometimes with a bit of caramel.
