Historical Beer: Roggenbier

BJCP 27

Overall Impression
A dunkelweizen made with rye rather than wheat, but with a greater body and light finishing hops.
Comments

Rye is a huskless grain and is difficult to mash, often resulting in a gummy mash texture that is prone to sticking. Rye has been characterized as having the most assertive flavor of all cereal grains. It is inappropriate to add caraway seeds to a roggenbier (as some American brewers do); the rye character is traditionally from the rye grain only.

History
A specialty German rye beer originally brewed in Regensburg, Bavaria. Never a widely popular style, it has all but disappeared in modern times.
Ingredients
Malted rye typically constitutes 50% or greater of the grist (some versions have 60-65% rye). Remainder of grist can include pale malt, Munich malt, wheat malt, crystal malt and/or small amounts of debittered dark malts for color adjustment. Weizen yeast provides distinctive banana esters and clove phenols. Light usage of Saazer-type hops in bitterness, flavor and aroma. Lower fermentation temperatures accentuate the clove character by suppressing ester formation. Decoction mash traditionally used (as with weissbiers).
