There are four levels of geographic classification, and any level of classification can be used on the label of Qualitätswein and Prädikatswein: Anbaugebiet, wine growing regions, of which there are 13. Anbaugebiet is always indicated on the label of Qualitätswein and Prädikatswein. Bereich, district, of which there are 39. Each Anbaugebiet is divided into one or more Bereiche. Großlage, collective site, which is a collective name for a number of single vineyards, and which number about 170. Einzellage, single vineyard, of which there are about 2,600. The names of Großlagen and Einzellagen are always used together with the name of a wine village, because some Einzellage names, such as Schlossberg (castle hill) are used in several villages. Unfortunately, it is not possible to tell a Großlage from an Einzellage just by looking at the wine label. A few examples of how the names appear on labels: The vineyard Sonnenuhr (meaning "sun dial") in the village Wehlen along the Mosel is designated as Wehlener Sonnenuhr. The neighbouring village Zeltingen also has a vineyard called Sonnenuhr, and will appear on the label as Zeltinger Sonnenuhr. Both these vineyards belong to Großlage Münzlay, which is assigned to the village Wehlen. A wine from any of these vineyards, or a blend from both of them, can be sold under the name Wehlener Münzlay. These vineyards lie within Bereich Bernkastel, which provides an additional choice for labelling. It is also possible to simply label the wine as a wine from Anbaugebiet Mosel. There are a few exceptions to the rule that a village must be indicated together with the vineyard name, those are a handful of historical vineyards known as Ortsteil im sinne des Weingesetzes (village name in sense of the wine law). Examples are Schloss Johannisberg in Rheingau and Scharzhofberg along the Saar. They are of the same size as a typical Einzellage and could be thought of as Einzellagen which were so famous that they were excused from displaying the village name. Labels Unlike French wine labels, where key information about the grape variety is not included in the labeling and thus must be known by the consumer to make an informed choice, German wine labels must display much more important information about the wine. It must always include: Geographic information with either the country, the city or the exact site of the wine (depending on the quality). The variety of grape(s) used
