German wine regions are classified according to the quality category of the wine grown therein: Tafelwein, Landwein, Qualitätswein bestimmter Anbaugebiete (QbA) and Prädikatswein. The wine regions allowed to produce QbA and Prädikatswein are further subdivided into four categories according to size: Anbaugebiet (a major wine region), Bereich (a district within the wine region), Großlage (a collection of vineyards within a district) and Einzellage (a single vineyard).[1] A small number of Einzellagen do not belong to a Großlage and are called "großlagenfrei", but all belong to a Bereich and Anbaugebiet.
The 13 major wine regions (Anbaugebiete) are Ahr, Baden, Franconia, Hessische Bergstraße, Mittelrhein, Mosel, Nahe, Palatinate, Rheingau, Rheinhessen, Saale-Unstrut, Saxony, and Württemberg. With the exceptions of Saxony and Saale-Unstrut, most of Germany's major wine regions are located in the western part of the country. As of 2010, there were 41 Bereiche, 160 Großlagen and 2,632 Einzellagen.[2]
