The Moselle, Saar and Ruwer rivers twist and turn in narrow loops through countryside where the Celts and Romans first cultivated wine 2,000 years ago. As a wine region, the Moselle is the oldest in Germany and the largest with vines on steep slopes. The Calmont, the steepest vineyard in Europe at a 68 degree incline, also rises up from the banks of the Moselle. Terraced hillsides and precipitous slopes, which face either south or south-west, create beneficial microclimates for wine grapes but also rare plants and animals. The sublime rieslings grown in these conditions in the Moselle, Saar and Ruwer vineyards rank among the finest white wines in the world with their wonderful mineral notes.
