Bock

Bock is a strong lager of German origin. Several substyles exist, including maibock (helles bock, heller bock), a paler, more hopped version generally made for consumption at spring festivals; doppelbock (double bock), a stronger and maltier version; and eisbock, a much stronger version made by partially freezing the beer and removing the ice that forms.

Originally a dark beer, a modern bock can range from light copper to brown in colour. The style is very popular, with many examples brewed internationally.

The style known now as bock was a dark, malty, lightly hopped ale first brewed in the 14th century by German brewers in the Hanseatic town of Einbeck. The style from Einbeck was later adopted by Munich brewers in the 17th century and adapted to the new lager style of brewing. Due to their Bavarian accent, citizens of Munich pronounced "Einbeck" as "ein Bock" ("a billy goat"), and thus the beer became known as "bock". To this day, as a visual pun, a goat often appears on bock labels.

Bock is historically associated with special occasions, often religious festivals such as Christmas, Easter or Lent (the latter as Lentenbock). Bocks have a long history of being brewed and consumed by Bavarian monks as a source of nutrition during times of fasting.

Bockfest, in Cincinnati, Ohio, is the longest running and largest bock beer festival in the world. The festival celebrates bock beer, the Cincinnati neighborhood of Over-the-Rhine, the city's German heritage, and the coming of spring.

Traditional bock is a sweet, relatively strong (6.3%–7.2% by volume), lightly hopped (20-27 IBUs) lager. The beer should be clear, and 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 mouthfeel is smooth, with low to moderate carbonation and no astringency. The taste is rich and toasty, sometimes with a bit of caramel. Again, hop presence is low to undetectable, providing just enough bitterness so that the sweetness is not cloying and the aftertaste is muted. The following commercial products are indicative of the style: Einbecker Ur-Bock Dunkel, Pennsylvania Brewing St. Nick Bock, Aass Bock, Great Lakes Rockefeller Bock, Stegmaier Brewhouse Bock.
