Rut Wiess Brau- und Vertriebsgesellschaft mbH is a German brewing company associated with the production of Rut Wiess, a traditional Kölsch-style beer rooted in the Rhineland brewing tradition. The name "Rut Wiess" is a reference to the red and white colours emblematic of the Cologne region, reflecting a strong local identity and cultural connection to the city and its surrounding area. The flagship beer, Rut Wiess Kölsch, is a top-fermented ale brewed in the classic Kölsch style: light in body, subtle in flavour, and refreshing in character. According to available sources, the beer is brewed with a high proportion of wheat malt, giving it a gentle and approachable profile that is well suited to the drinking culture of the Rhineland. As a top-fermented specialty, it aligns with the long-standing tradition of Kölsch brewing that defines the Cologne beer scene.
