Rivalry with Düsseldorf

Cologne and Düsseldorf have a " fierce regional rivalry ", which includes carnival parades, ice hockey, football, and beer. People in Cologne prefer Kölsch while people in Düsseldorf prefer Altbier ("Alt"). Waiters and patrons will "scorn" and make a "mockery" of people who order Alt beer in Cologne or Kölsch in Düsseldorf. The rivalry has been described as a "love–hate relationship". The Köln Guild of Brewers was established in 1396. The Kölsch beer style first appeared in the 1800s and in 1986 the breweries established an appellation under which only breweries in the city are allowed to use the term Kölsch.
