"grand vin de bordeaux" is a first-class Bordeaux winery (Lafite, Latour, Margaux, Semillon) and also a Bordeaux AOC red wine. There are also great differences in classification. Usually, the smaller the nominal producing area on the wine label, the higher the quality of the wine, so the wine in the winery is the most expensive.

AOC is the highest grade French wine, and its grape varieties, minimum alcohol content, maximum yield, cultivation methods, pruning and brewing methods are all under the strictest monitoring.

Only wines from legal producing areas that have passed the official analysis and test can obtain the A.O.C certificate. It is this very strict regulation that ensures the consistent noble quality of A.O.C wines.

Extended data

The nobleness of Bordeaux red wine stems from its long and meticulous brewing method: in the process of grape juice fermentation, the time of soaking skin controls the clear and moving color of wine and the tannin content in wine.

After fermentation, it is a slow and patient process to extract the wine residue that has settled at the bottom of the fermentor. The next step is to choose the best quality wine and combine different varieties of wine in perfect proportion.
