The vineyards of the German growing area lie in the state Rheinland-Pfalz as well as to a small extent also in the state Saarland. The 8,976-hectare vineyards are along the Moselle from the headwaters in the Vosges Mountains on the border Luxembourg until its confluence with the Rhine at Koblenz and at the two tributaries Saar and Ruwer. These three rivers gave the cultivation area the old name Mosel-Saar-Ruwer, which was valid until autumn 2007. The river Moselle winds its way from Trier to Koblenz over 237 km, but the airline is only 96 km. On the upper Mosel are the oldest vineyards Germany, here already the Romans operated in the 1st century BC.
