The Rhine and some of its tributaries such as Main, Nahe and Neckar are particularly in Germany viticulture an eminent importance. Because on the sometimes steep slopes of these rivers, a large part of the German vineyards in 10 (of 13) directly adjacent or nearby German cultivation areas. The importance of the river also highlights the fact that the most important German grape variety Riesling often called Rheinriesling. The Rhine practices like everyone else waters a positive effect on viticulture from or creates the basis for the formation of valley slopes.
The 1,233-kilometer-long stream has its source in the canton Grisons in the swiss alps. After the confluence of Vorderrhein and Hinterrhein at Tamins-Reichenau it is called Alpenrhein and flows through the Lake Constance, After flow of the upper lake it is called in the four-kilometer section Seerhein , flows through the submarine and is called after the exit at Stein am Rhein now Hochrhein . This forms the border between Switzerland in the south and Germany in the north to Basel.
The now about 350 kilometers long section between Basel at the border triangle (Germany, France, Switzerland) and Bingen is called Upper Rhine . The cultivation area east of the river Franconia is from across from Mainz opening into the Rhine Main traversed in a large W-shape. East of the Upper Rhine stretches for 300 kilometers in the Upper Rhine Plain from Lake Constance to Frankfurt am Main the growing area to bathe, At the Neckar, which flows into the Rhine near Mannheim, and its tributaries, lies the bulk of the vineyards of the neighboring cultivation area to the east of Baden Wuerttemberg,
West of the Rhine knee near Wiesbaden lies north of Bingen in the form of a narrow strip, the growing area Rheingau, Just below that closes west of the Rhine, the largest German wine-growing region Rheinhessen at. South is the cultivation area palatinate with its easternmost vineyards near the Rhine. On the Rhine knee to Bingen flows the Near into the Rhine, which gave the cultivation area adjacent to the west to Rheinhessen. The Near estuary borders the Upper Rhine from the Middle Rhine.
The 130-kilometer section of the Middle Rhine stretches from Bingen and Rüdesheim am Rhein in the south to Bonn-Bad Godesberg in the north. At Koblenz flows the Moselle which gave the name to the region west of the Rhine. North of it is also named after a tributary area Ahr, Largely identical to the geographical region is the small wine-growing region middle Rhine, Here you will find 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 border with the Rhine division begins the extensive Rhine-Maas-Delta (rarely also Rhine-Meuse-Scheldt-Delta). This is the common estuary of the rivers Rhine (with the three main strands Waal-Boven, Nederrijn-Lek and IJssel), Maas and Schelde in the North Sea.
