The highest density of breweries in the world is found in Aufseß near the city of Bamberg, in the Franconia region of Bavaria with four breweries and only 1,352 citizens.[17] The Benedictine abbey Weihenstephan brewery (established in 725) is reputedly the oldest existing brewery in the world (brewing since 1040). In 2004, Oettinger replaced Krombacher as the best selling brand in Germany.[18]
