Mandatory sensory and analytical test for quality wines and paedikat wines in Germany (this is not necessary for the two quality levels of wine and Landwein ). The official test number, which must be stated on the label, is issued as proof that the test has been passed. From this number, the testing centre, producer and vintage can be clearly and unequivocally traced. The wine may no longer be altered from the start of the application until the end of the procedure and from the time of issue.

These include sulphurisation, the addition of ascorbic acid and metatartaric acid as well as filtration (but not the various fining techniques).
