French law divides French wine into 4 levels: 1. Wine from legal production area (AOC), 2. Regional fine wine (VDQS), 3. Regional table wine (VDP), 4. Everyday table wine Wine (VDT)

Legal production area wine, abbreviated as AOC, is the highest level of French wine:

AOC means "Controlled Designation of Origin" in French. The grape varieties, planting quantity, brewing process, alcohol content, etc. in the area of ??origin must be certified by experts. It can only be brewed with grapes grown in the place of origin and must not be blended with grape juice from other places. AOC production accounts for approximately 35% of France's total wine production. The wine bottle label is marked as Appellation+region name+Controlee.

Excellent regional table wine, abbreviated as VDQS:

It is the level that ordinary regional table wine must go through to transition to the AOC level. If the wine performs well during the VDQS period, it will be upgraded to AOC. Production accounts for only 2% of France's total wine production. The bottle label is marked as Appellation+region name+Qualite Superieure.

Regional table wine VIN DE PAYS (meaning Wine of Country in English):

The best wines among daily table wines are upgraded to regional table wines. Regional wine labels can indicate the region of origin. It can be blended with grape juice from the production area indicated, but only from grapes in that production area. Production accounts for approximately 15% of France's total wine production. The bottle label is marked Vin de Pays + the name of the region. Most of France's regional table wines are produced along the southern Mediterranean coast.

Daily table wine VIN DE TABLE (English meaning Wine of the table):

It is the lowest-end wine for daily drinking. It can be made by blending grape juice from different regions. If the grape juice is limited to various production areas in France, it can be called French daily table wine. Grape juice from countries outside Europe must not be used. Production accounts for approximately 38% of France's total wine production. The wine bottle label reads Vin de Table. Asking further, 35%+2%+15%+38% is only 90%? What is the remaining 10%?
