Märzen or Maerzen is a traditional pale lager, the origins of which go back to at least the sixteenth century. Brewed at the end of the brewing season in March ("März" in German), it was a stronger beer intended to last through the summer months.
The German style is most often characterized by a medium to full body, a malty flavor balance, a wide range of colors, and a clean, dry finish, though wide variations are notable among German breweries marketing Märzen. Amongst these variations are colors ranging from pale to dark brown.
The North American style normally exhibits a stronger, though not aggressive, hop aroma and bitterness balance. The Austrian style closely resembles a Helles in color, body, and flavor balance, and is the most popular beer style in Austria.
