Rheingau (wine region)
Rheingau is one of 13 designated German wine regions ("Weinbaugebiete") producing quality wines ("QbA" and "Prädikatswein"). It was 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 of vineyards in 2016, also boasts a higher  proportion of Riesling (77.7%) than any other German wine-growing region, with Spätburgunder (Pinot noir) making up most of the rest (12.2%), followed by Müller-Thurgau. Geography and terroir. The geography of the Rheingau is very distinct. Around Wiesbaden, the river Rhine detours from its northward flow west for about 30 km before it flows north again. The greater part of the Rheingau is situated here on the river's right bank, but the region also includes the stretch along Rhine after it turns northward again, around the villages Assmannshausen and Lorch. The vineyards in Hochheim on the Main river  are also included, just before it flows into Rhine, as is the vineyard of Lohrberger Hang situated slightly east of the centre of Frankfurt am Main. The Rheingau spans about 50 km from end to end. North of the Rheingau rises the Taunus mountain range, so most of the Rheingau's vineyards are on south-facing slope between mountains and rivers, which provides excellent wine-growing conditions in these northerly latitudes. History. Since the Verona donation in 983, the Rheingau belonged to the archbishopric of Mainz. Legend has it that Charlemagne let the first vineyards be planted in the region , close to present-day Schloss Johannisberg. However finds like a Roman origin grapevine cutting knife point to even earlier cultivation. Better documented is the early influence of the church on Rheingau winemaking, which was controlled from Eberbach Abbey. Augustinians and Benedictines are known to have inhabited the area of the later abbey from 1116, and in 1135 the Cistercians arrived, sent out from Clairvaux. Legend has it that the Cistercians, which are also credited with having founded the wine industry in Burgundy, brought Pinot noir with them to Rheingau, although the earliest record of the grape variety in Rheingau is  from 1470. The slopes down from the Taunus mountains belonging to Eberbach Abbey were planted as vineyards in the 12th century, and early in the 13th century the vineyards had reached their present area. In medieval times, more red than white wine was produced, usually as Gemischter Satz, i.e. the vineyards were planted with mixed varieties which were vinified together. In 2011 it was unveiled, that the Official Wine Classification in the Rheingau has a 150 years history. The classification was the basis for taxation of wineries after the annexation of the Duchy of Nassau by the in 1866. In  the book "Der nassauische Weinbau" published in 1867 by Friedrich Wilhelm Dünkelberg a historical map "Weinbau-Karte des nassauischen Rheingaus" (Viticultural map of the Rheingau in the Duchy of Nassau), all known vineyards at that time had been marked up by colour, evaluated and classified in first class vineyards (I. Klasse), second class vineyards (II. Klasse) and the remaining vineyards . As first class vineyards (I. Klasse) only 13 Lagen in 9 boundaries had been classified: Villages and producers. Some villages of Rheingau, listed in the downstream direction of Rhine, with some notable vineyards and producers. Grape varieties. The most cultivated  grape varieties, by area in 2019, were:
