Bolten Brauerei is one of the oldest breweries in the world, located in Korschenbroich in the Lower Rhine region of North Rhine-Westphalia, Germany. Its origins date back to 1266, when the Lord of Myllendonk officially authorised the brewing of beer on the site. Based on this remarkable founding date, Bolten lays claim to being the oldest Altbier brewery in the world — a title that connects the brewery deeply to the cultural and brewing heritage of the Lower Rhine area. Centuries of tradition have shaped the identity of this storied institution. Bolten Brauerei is best known for its Altbier, the copper-coloured, top-fermented beer style that is closely associated with the Lower Rhine and Düsseldorf regions of Germany. Altbier is characterised by its balanced bitterness, malt-forward character and clean finish — a style that Bolten has been refining for hundreds of years. The brewery's portfolio centres on this traditional style, reflecting a commitment to regional brewing culture and craftsmanship rooted in the landscape and ingredients of the Lower Rhine. Bolten Alt, the brewery's signature beer, is brewed in Korschenbroich and represents one of the most authentic expressions of the Altbier style available today. The brewery's long history and regional roots have earned it a respected place among German beer lovers and international enthusiasts alike, making it a landmark destination for those exploring the rich brewing traditions of North Rhine-Westphalia.
