Franconia (wine region) in the context of "German wine classification"

The German wine classification system puts a strong emphasis on standardization and factual completeness, and was first implemented by the German Wine Law of 1971. Nearly all of Germany's vineyards are delineated and registered as one of approximately 2,600 Einzellagen ('individual sites'), and the produce from any vineyard can be used to make German wine at any quality level, as long as the must weight of the grapes reaches the designated minimum level. As the current German system does not classify vineyards by quality, the measure of wine ’quality’ is the ripeness of the grapes alone.

Approximately 200 wine makers have been organised since 1910 in the Verband Deutscher Prädikatsweingüter (VDP). To counter the shortcomings of the 1971 law, the VDP nowadays classifies the best vineyards by its own rules into 'VDP.Grosse Lage' (Grand cru) and 'VDP.Erste Lage' (Premier cru) based on 19th century Prussian tax maps. Most of these wine makers are based in the regions of Mosel, Pfalz, and Franken.
