Hausbrauerei Zum Schlüssel

Hausbrauerei Zum Schlüssel is a house brewery at Bolkerstraße 43-47 in Düsseldorf's Altstadt, North Rhine-Westphalia, Germany, on the old town's main bar street. It brews Altbier on site, with Schlüssel Alt as the standard pour and the seasonal Gatzweilers Alt as a second beer. The context is brewing tradition rather than a chef or Michelin background. The menu follows classic Rhenish cooking. Schweinshaxe, the roast pork knuckle, and Rheinischer Sauerbraten are the substantial mains, and Himmel un Ääd, a regional dish of black pudding served with apple and mashed potato, is the most distinctly local plate. These pair with the dark, bitter Alt, which is the central beverage. The room is lively, with long wooden tables, a steady flow of beer from the barrel, and a mixed crowd of locals, office groups and visitors passing along Bolkerstraße. Dress is casual and the volume is high on weekend evenings, when the surrounding street fills with people moving between bars. Weekday afternoons are calmer and better suited to a meal with conversation. Small parties can usually walk in and find a place at a shared table, while groups should book by phone. Prices are moderate: the beer is served by the small glass, so costs depend on how many rounds are ordered, and mains sit at the usual Altstadt brewhouse level. The brewhouse is a short walk from the Rhine promenade and the Marktplatz, and it is directly next to other traditional houses, including Im Goldenen Kessel on the same street, so it fits easily into a walking route through the old town. Visitors interested in the difference between houses can sample the Schlüssel Alt here and compare it with the neighbouring brews.
