The CVRVV's Tasting Panel consists of a Head Taster and three members.

Wine samples are labelled "blind" by series to ensure confidentiality and are individually tasted by members of the tasting panel, who then enter their comments on the respective forms which are examined and discussed before the writing of the final report.

In the event of the entire Panel cannot reach an agreement as to the sensorial analysis of a sample, the Head Taster may exercise his right to veto the conclusions regarding the wine, or wines, in question. The matter in then submitted to the Appeals Committee, the "body of last resort", whose decision is irrevocable.

The Appeals Committee only meets following a veto or upon the request of the supervisory entity.
