Bock

A strong, malty German lager, smooth and warming, with deep bready and toasty malt.

About the Bock style

The bock is a strong lager that originated in the German town of Einbeck in the Middle Ages and was later adopted by Munich brewers. The name became associated with a billy goat, which appears on many bock labels.

It is a malt-driven beer, strong but smooth, traditionally brewed for seasonal occasions. Stronger and darker variants such as doppelbock and the pale, potent maibock grew from it.

Bock is a strong German beer, usually a dark lager.

Grain, hops and yeast

Malt and grain: Munich and Vienna malts for a rich, bready, toasty malt profile.

Hop character: Low noble hopping for balance, well behind the malt.

Yeast and fermentation: A clean lager yeast able to ferment the higher gravity cleanly, lagered long.

A typical Bock runs 6.3 to 7.2% alcohol by volume, with a bitterness of about 20 to 27 IBU and a colour of 14 to 22 SRM. It is traditionally served in a willi becher or goblet. These figures describe the usual range for the style; a given example may sit a little outside them.

Yeast and fermentation notes

A clean lager yeast, pitched in a large healthy dose and fermented cold around 9 to 12 degrees Celsius, ferments the higher gravity without stress. A long cold lager smooths the strength and lets the rich Munich malt shine.

Serving in brief

Serve a bock cool, around 7 to 10 degrees Celsius, with a moderate carbonation, in a sturdy glass or goblet. It is a strong, warming lager, so pour measured servings and let its malt open up as it warms slightly.

Classic examples

Well-known commercial examples of the style include Einbecker Ur-Bock, Aass Bock and Great Lakes Rockefeller Bock. Tasting a benchmark example is the best way to understand what a style should be before brewing your own.
