The Rheingau (English: Rhine District) is the hill country on the north side of the Rhine River between Wiesbaden and Lorch near Frankfurt, reaching from the western Taunus to the Rhine.
Rheingau is one of 13 designated German wine regions (Weinbaugebiete) producing quality wines (QbA and Prädikatswein). Named after the traditional region of Rheingau (meaning "Rhine district"), the wine region is situated in the state of Hesse, where it constitutes part of the Rheingau-Taunus-Kreis administrative district. Although making up only 3 percent of the total German vineyard area, Rheingau has been the source of many historically important innovations in German wine making, and contains many wine producers of international reputation, such as Schloss Johannisberg. Rheingau, with 3,125 hectares (7,720 acres) of vineyards in 2008, also boasts a higher proportion of Riesling (78.8%) than any other German wine-growing region, with Spätburgunder (Pinot noir) making up most of the rest (12.2%), followed by Müller-Thurgau (1.6%)
