The wine-growing area is largely located in the state of Rhineland-Palatinate in Germany, with a small area in North Rhine-Westphalia. The vineyards cover 470 hectares of vines, stretching from the municipality of Oberdollendorf near Königswinter, opposite Bonn, to north of Bingen, partly on both banks of the namesake middle course of the Rhine. The city of Koblenz lies at the heart of this beautiful river landscape. Winegrowing was established here by the Romans after the founding of the cities of Cologne (Colonia) and Bonn (Bonna). It flourished in the Middle Ages under the leadership of the Cistercians, who built the Heisterbach Monastery above Oberdollendorf, which is now only in ruins. The town of Bacharach is an ancient wine trading centre.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.Sigi Hiss
