Dunkel, or Dunkles, is a word used for several types of dark German lager. Dunkel is the German word meaning dark, and dunkel beers typically range in colour from amber to dark reddish brown. They are characterized by their smooth malty flavour. In informal terms, such as when ordering at a bar, "dunkel" is likely to mean whatever dark beer the bar has on tap.
Many dunkels have a distinctive malty flavour that comes from a special brewing technique called decoction mashing. Most commonly, dunkel beers are dark lagers, but the term is also used to refer to dark wheat beers such as Franziskaner Hefe-Weisse Dunkel. Dunkel weizen is another term used to refer to dark wheat beers, which are fruity and sweet with more dark, roasted malts than their lighter counterpart, the hefeweizen
