The Rheingau (German: [ˈʁaɪnɡaʊ] ; lit.'Rhine County') is a region on the northern side of the Rhine between the German towns of Wiesbaden and Lorch near Frankfurt, reaching from the Western Taunus to the Rhine. It is situated in the German state of Hesse and is part of the Rheingau-Taunus-Kreis administrative district. It is famous for Rheingau wines, especially the "Rheingauer Riesling," and its many taverns.[1]
