Amtliche Prüfungsnummer (A.P. Nr.)
When German regulatory officials certify that a German wine has met all requirements, including taste testing, to be labelled as qualitätswein (and so also prädikatswein) they assign it a certification number, an “amtliche prüfungsnummer” (/omt-lish-ǝ prūef-ūngs-nūm-ur/) or “A.P. Nr.” The number is a code with specific meanings. For example, in the Federal German state of Rhineland Pfalz (the Mosel, Pfalz, Ahr, Mittelrhein, Nahe, and Rheinhessen) the first three groupings of numbers in the sequence designate a specific bottler and the last two designate the lot and year of examination. For example, the A.P. Nr. given to the 2011 Frühburgunder from the Winzergenossenschaft Mayschoss-Altenahr is 1 794 190 033 12. The “1” designates the examination board, “794” the bottler’s location (here the winery is the bottler), and “190” is the bottler’s identification number (here also the winery). “033” is the testing lot number and the “12” is the year it was tested (note how that is not the same as the vintage).
