Altbier

BJCP 7b

Overall Impression
A well-balanced, well-attenuated, bitter yet malty, clean, and smooth, amber- to copper-colored German beer. The bitterness is balanced by the malt richness, but the malt intensity and character can range from moderate to high (the bitterness increases with the malt richness).
Comments

A top-fermented lagered beer, fermented at cool ale temperature (59–68 °F), often conditioned at bottom-fermentation temperatures (about 50 °F) and then lagered at cold temperatures to produce a cleaner, smoother palate than is typical for most ales. Zum Uerige is a wonderful beer, but much more aggressively bitter and complex than most other German examples. It may be like the Fuller’s ESB of the strong bitter category – well-known but somewhat of a stylistic outlier.

History
The traditional style of beer from Düsseldorf. “Alt” refers to the “old” style of brewing (i.e., using top-fermenting yeast) that was common before bottom-fermenting lager brewing became popular. Predates the isolation of bottom-fermenting yeast strains, though it approximates many characteristics of bottom-fermenting lager beers. Many of the classic examples can be found in brewpubs in the Altstadt (“old town”) section of Düsseldorf.
Ingredients
Grists vary, but usually consist of German base malts (usually Pils, sometimes Munich) with small amounts of crystal, chocolate, and/or black malts used to adjust color. Occasionally will include some wheat, including roasted wheat. Spalt hops are traditional, but other Saazer-type hops can also be used. Clean, highly attenuative ale yeast. A step mash or decoction mash program is traditional.
