Wine activities
In the area of German wine, DLG has been responsible for devising the assessment scale used for official classification as well the medals and awards that are handed out regionally and nationally. This is a five-point scale where the wines are assessed blind (i.e., the tasters don't know the identity of the wine in the glass) by a panel and given points in the three categories bouquet ("nose"), taste and harmony. The category "harmony" refers to all sensory impressions, including color, and is concerned with the overall balance between sweetness, acidity, alcohol and "body"/mouthfeel of the wine. Each category is assessed on the scale 0-5 (fractional points may be awarded), and the points given are then averaged, with the same weight given to the three categories. For a wine to be given its quality control test number (A.P. Number for Amtliche Prüfung) necessary to display a Prädikat designation of the German wine classification, a minimum of 1.5 out of 5 is necessary in all three categories, otherwise the wine is denied a classification.
