Rheinhessen is located on the Rheinbogen between Mainz, Worms and Bingen and is the largest German wine-growing region. In the warm, dry climate at the 50th parallel, 70% of white grape varieties grow - especially Riesling, Müller-Thurgau and Silvaner. Dornfelder and Pinot Noir dominate the reds. The definition of the ripeness levels, the methods of winemaking and the sensory testing of the wines from the Rhein-Hesse PDO are subject to the regulations of the European Union (EU) and are at the same time an expression of the millennium-old wine culture on the Rhine. "Rheinhessen" is a protected designation of origin.
