Abbreviation for Official Inspection Number
Official test number
It is issued to a wine that has been recognized by the examining authority as a quality or predicate wine. The Official Exam Number (APNr.) Is composed of this word or abbreviation, the farm number (consisting of the number of the inspection body, the number of the place of filling 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 them a quality wine may not be placed on the market
The total alcoholic strength of a wine is determined by the actual alcoholic strength (= the sweetness of the must fermented to alcohol) and the potential alcoholic strength (if the remaining residual sugar is still fermented to alcohol).
