Altbier is Düsseldorf’s beer. It ranges from amber to copper in color, is top-fermented, and has a hoppier bitterness than pale beers. The name Alt, meaning "old," refers to the traditional fermentation method—yeast that works at the top of the tank—not to the beer’s age.
According to the city’s tourism information, Altbier has been brewed in Düsseldorf from a recipe almost unchanged since the mid-19th century. The city has six brewery-taverns, and five of them have their main house in the Altstadt, the old town. Each has its own Altbier, and locals enjoy arguing about which is best. Düsseldorf’s tourism presents Altbier as a traditional craft beer, hand-made long before the microbrewery trend.
The place to taste it is the brewery itself, where Alt is poured fresh from the cask. Waiters, also called Köbes as in Cologne, bring low 0.2-liter glasses and keep serving until you place the coaster on top of your glass. The waiter’s curt manner is part of the tradition and, according to tourism information, is cordial in its own way.
The Altstadt, with more than 260 bars, taverns and restaurants in half a square kilometer, is nicknamed the "longest bar in the world." On summer nights many people drink standing on the sidewalk in front of the breweries. The rivalry with Cologne’s Kölsch, 40 kilometers away, is a long-standing matter between the two cities.
