Märzen, which has become known as Oktoberfest due to the annual festival with the same name, was originally described as dark brown and full-bodied. The beer was often kept in a cellar until late in the summer, and each year remaining bottles were served at the Oktoberfest. The style is characterized by a medium to full body, a malty flavor and a clean dry finish. In Germany, the term covers beers which vary in color from pale through amber to dark brown. The North American style normally exhibits a stronger, though not aggressive, hop aroma and bitterness balance.
