Dusseldorf Altbier – All Grain

Statistics

General Info

My interpretation of the classic Dusseldorf style Alt. Intended to have a good balance of malt and hop bitterness. Perfect for an evening by the campfire. Style calls for a lagering period after fermentation.

I entered this into the Foam on the Range annual competition. From what the judges said (see the reviews below), it was a good beer, but not a Dusseldorf Alt. Generally, it was too dark and too malty for a Dusseldorf.

But what is it? Maybe a North German Alt? I honestly don’t know, and the judges didn’t give any suggestion as to style. I tweaked the recipe a bit to be more stylistically accurate - as a North German Alt. Live and learn.

Comments

Brewed on a picture perfect Friday evening in early summer. Racked to primary and took a gravity reading...surprisingly, a bit higher than expected. I’m excited about this one ? looked good, smelled good while perculating. I really haven’t tasted this style before. I’ll compare when this one is ready.

Substituted Libery for Spalt hops. Brew store was out of Spalt (June 29, 2007).

Racked to secondary (July 9, 2007).

Racked to keg and began lagering process (July 28, 2007).
