The German wines are divided into 3 quality levels: German table wine, quality wine b.A. and Prädikatswein. In which group a wine is to be classified depends on must weight, ripeness and type of harvest. In the case of quality wine (with or without predicate), it is assigned by the tasting center. The quality level is indicated on the label.
A Quality wine must be made from certain grape varieties (given on a list). The grapes must be harvested exclusively in Rheinhessen (no blend of different areas). The wine must be typical in appearance, smell and taste, it must be free of defaults typical for origin and grape variety.
