 Among these are "Altbier", a dark beer available around Düsseldorf and the lower Rhine, "Kölsch", a similar style, but light in color, in the Cologne area, and the low-alcohol "Berliner Weiße", a sour beer made in Berlin that is often mixed with raspberry or woodruff syrup.Since the reunification of 1990, "Schwarzbier", which was common in East Germany, but could hardly be found in West Germany, has become increasingly popular in Germany as a whole.Beer may also be mixed with other beverages such as pils or lager and carbonated lemonade
