The wine-growing region is located in Rhineland-Palatinate and to a small extent also in Saarland in Germany. The Moselle River winds its way from Trier to Koblenz over 237 km, but as the crow flies it is only 96 km. The vineyards cover 8,798 hectares of vines, stretching along the Moselle from its headwaters in the Vosges Mountains on the border of Luxembourg to its confluence with the Rhine near Koblenz, as well as along its two tributaries, the Saar and the Ruwer. These three rivers gave the wine-growing region the old name Mosel-Saar-Ruwer, which was valid until 2007. Germany's oldest vineyards are located on the upper Moselle; the Romans were already cultivating vines here in the 1st century BC and founded the city of Augusta Treverorum, today's Trier, in 15 BC. Remains of old Roman presses can still be seen in Piesport and Erden. The Neumagen wine ship also points to Roman wine culture. The two Roman poets Ausonius (310-395) and Venantius Fortunatus (530-610) described the beauty of the landscape during boat trips on the Moselle. In the Middle Ages, the Benedictine order owned many vineyards along the banks of the three rivers, to which many individual vineyard names testify.
