While Weingut Franz Keller is primarily known for its Sptburgunder (Pinot Noir) and Burgundian-style white wines (Chardonnay, Grauburgunder, and Weissburgunder), they also produce high-quality Riesling. Their Rieslings reflect the volcanic and loess soils of the Kaiserstuhl region in Baden, Germany with minerality, bright acidity, and a refined structure.
