German wine classification
（重定向自QBA）
The German wine classification system puts a strong emphasis on standardization and factual completeness, and was first implemented per the German Wine Law of 1971. Almost all of Germany's vineyards are delineated and registered as one of approximately 2,600 Einzellagen ('individual sites'), and the produce from one can be used to make wine at any quality level, depending not on yields but on the ripeness, or must weight of the grapes.
