Mittelrhein (or Middle Rhine) is a region (Anbaugebiet) for quality wine in Germany, and is located along a 120 km stretch of river Rhine in the tourist portions of the Rhine region known as Middle Rhine. On the left bank of Rhine, vineyards begin immediately downstream of the Nahe River estuary and last until Koblenz. On the right bank, vineyards begin where Rheingau ends and last until 8 kilometers south of Bonn, in the Siebengebirge. Parts of the Rhine Gorge, a UNESCO World Heritage since 2002, make up the southern part of Mittelrhein.
