Location and landscape
The Rheingau is a German quality winegrowing region on the right bank of the River Rhine. It stretches from the area of Frankfurt am Main via Wiesbaden to Lorch, and lies north of Rüdesheim. The region follows the course of the river over a distance of around 50 kilometres. Near Wiesbaden the Rhine changes direction: it flows about 30 kilometres west and turns back to the north again at Rüdesheim.
The Rhine bend and the Rheingau mountains create predominantly south-facing vineyard sites. In the west, near Lorch, there are steep vineyard areas in the Rhine valley. In total, the area under vine covered 3,117 hectares in 2025, with 129 registered individual sites.
Climate and soils
The Rheingau has warm, dry summers and mild winters. The elevations of the Taunus protect against cold winds, while the Rhine contributes to warming by reflecting heat. For the period 1991 to 2020, a mean annual temperature of 11.0 °C, a mean temperature of 15.7 °C during the growing season, an average annual rainfall of 526.5 millimetres and around 1,701 hours of sunshine are given.
Geologically, the Rheingau belongs to the Mainz Basin and the Rhenish Slate Mountains. The vineyards feature, among other things, tertiary marine and brackish sediments, loess and loess clay, phyllite, clay slate, quartzite, quarzitic sandstone and, locally, tertiary limestone. On the Rüdesheim mountain, in Lorch and in Assmannshausen, slate and phyllitic slate predominate.
Grape varieties and wine styles
The most important grape varieties are Riesling and Spätburgunder. In 2025, Riesling occupied an area of 2,355 hectares, while Spätburgunder covered around 390 hectares. Assmannshausen is particularly associated with Spätburgunder.
The documented range includes dry and delicately off-dry Rieslings, Riesling Spätlese as well as full-bodied Spätburgunder red wines. Rheingau Riesling is made from dry to noble-sweet, with acidity being a shaping structural element. In the steep sites near Lorch, the slopes can reach up to 70 per cent gradient; there, according to regional documentation, complete hand-harvesting is required.
History and wine law
The Eberbach monastery was founded by the Cistercians. Winegrowing continued there in the Middle Ages and was later associated with the production of Riesling and Spätburgunder. In 1775, the monastery in Johannisberg documented the advantage of a late harvest.
Rheingau is a protected designation of origin for wine, Qualitätsperlwein (quality sparkling wine) and Qualitätsschaumwein (quality carbonated sparkling wine). The quality wine examination is carried out by the winegrowing specialist division at the Regierungspräsidium Darmstadt (Regional Council of Darmstadt) in Eltville.
