It is French and means Bordeaux’s high-quality production area.

Generally, AOC wines will have this line, which proves that the wine is a high-quality wine from the Bordeaux region. But it does not mean that it is top-notch. GRAND VIN DE BORDEAUX literally translates from French as "Bordeaux fine wine". The wine labeled "GRAND VIN" has better quality and taste, and the quality is more guaranteed.

This name has nothing to do with AOC classification, and the reality may be different from the theory. Wines that are slightly better than the average Bordeaux AOC are often labeled Grand Vin.
