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, 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.

German wine is primarily produced in the west of Germany, along the river Rhine and its tributaries, with the oldest plantations going back to the Roman era. Approximately 60 percent of German wine is produced in the state of Rhineland-Palatinate, where 6 of the 13 regions (Anbaugebiete) for quality wine are situated. Germany has about 103,000 hectares of vineyard, which is around one tenth of the vineyard surface in Spain, France or Italy. The total wine production is usually around 10 million hectoliters annually, corresponding to 1.3 billion bottles, which places Germany as the eighth-largest wine-producing country in the world. White wine accounts for almost two thirds of the total production.
