Abbreviation for "Amtliche Prüfnummer" (Official Inspection Number)
It is given to a wine, that has been recognized by the examining authority as a quality or predicate wine. The Official Inspection Number (APNr.) is composed of the abbreviation of this word, the farm number (consisting of the number of the inspection body, the number of the place of bottling and the code number of the bottling plant) and application number and year. Example: At the APNr. 4 725 012 001 16 would therefore be 4 = reference number of the Alzey testing center, 725 = place (registered office) of the bottler, 012 = code of the bottling plant, 1 = application number (lot) of the holding, 16 = year of application. The APNr. must therefore be on the label. Without it, a quality wine must not be placed on the market
The total volume of alcohol of a wine is determined by the actual alcoholic volume (= the sweetness of the must fermented to alcohol) and the potential alcoholic volume (if the remaining residual sugar is fermented to alcohol, too).
