Dusseldorf Altbier is a malty pale beer from the city of Dusseldorf. Altbier is also called "old beer". Altbier uses a top fermenting ale yeast at ale temperature, but then is cold-aged. This refers to the "Old" method before lagers became popular.
Altbier is, as it name implies, an old beer and in fact is one of the older surviving styles in Germany. Before the popularity of lagers, ales were widely brewed in Germany. Dusseldorf Altbier is a popular and excellent example of these older beers.
