The Rhine and some of its tributaries such as the Main, Nahe and Neckar are particularly popular in Germany of eminent importance with regard to viticulture. Because on the sometimes steep slopes of these rivers, a large part of the German vineyards is located in 10 (out of 13) directly adjacent or in the immediate vicinity of German cultivation areas. The importance of the river also highlights the fact that it is the most important German grape variety Riesling is often called Rheinriesling. The Rhine practices like everyone else waters a positive effect on viticulture or creates the conditions for this by forming valley slopes.
The total 1,233 km long river, of which 857 km in Germany, originates in the canton Grisons in the Swiss Alps. After the confluence of the Vorderrhein and Hinterrhein near Tamins-Reichenau, it is called the Alpenrhein and flows through it Lake Constance, After flowing through the Obersee, it is called Seerhein in the four km section, flows through the Untersee and is now called Hochrhein after leaving Stein am Rhein. Up to Basel, this forms the border between Switzerland in the south and Germany in the north.
The now following approximately 350 km long section between Basel am Dreiländereck (Germany, France, Switzerland) and Bingen is called the Upper Rhine . The growing area east of the river Franconia is from the opposite of Mainz flowing into the Rhine Main flowed through in a large W shape. East of the Upper Rhine extends 300 km in the Upper Rhine Plain from Lake Constance to Frankfurt am Main the growing area to bathe, Most of the vineyards in the wine-growing region east of Baden are located on the Neckar and its tributaries, which flow into the Rhine near Mannheim Wuerttemberg,
To the west of the Rhine knee near Wiesbaden, north of Bingen, the cultivation area is in the form of a narrow strip Rheingau, The largest German cultivation area closes just below this to the west of the Rhine Rheinhessen on. The growing region is to the south palatinate with its easternmost vineyards near the Rhine. At the Rhine knee to Bingen it flows Near into the Rhine, which gave the cultivation area bordering on the west of Rheinhessen the name. The near estuary separates the Upper Rhine from the Middle Rhine.
The 130 km section of the Middle Rhine extends from Bingen and Rüdesheim am Rhein in the south to Bonn-Bad Godesberg in the north. At Koblenz it flows Moselle which gave the cultivation area west of the Rhine its name. To the north of this is the cultivation area, also named after a tributary Ahr, The small wine-growing region is largely identical to the geographical region middle Rhine, Here there are the tributaries Lahn, Wied and Sieg on the right bank of the Rhine. The last section from Bonn is now called Niederrhein (Nederrijn). On the Dutch-German state border, the extensive Rhine-Meuse Delta begins with the division of the Rhine (more rarely also the Rhine-Meuse-Scheldt Delta). This is the common confluence of the Rhine rivers (with the three main strands Waal-Boven, Nederrijn-Lek and IJssel), Meuse and Scheldt into the North Sea.
