What do you think of French red wine grades?
(1) daily table wine (VDT)
VDT is the lowest grade wine in France and is only used as a daily table wine. This kind of red wine is blended with grape juice from different regions, and it is limited to the use of French grape juice, and the grape juice from other countries outside the European Union is not acceptable. This kind of wine accounts for 38% of the total output in France, and only the variety and year are allowed to be marked on the bottle label, which is generally marked as "Vin de Table/France".
(2) regional table wine (VDP)
Better wine in daily table wine can be upgraded to VDP, and the label of regional table wine can indicate the origin of wine, or the name of grapes used for brewing in this producing area can be indicated on the label. The wine production of this grade accounts for 15% of the total French production. The general label is "Vin de Pays+ the name of the producing area", but now, some of them have been changed to "IGP".
(3) Excellent Area (VDQS)
VDQS red wine only accounts for 2% of the total French red wine. This grade of wine is also called quasi-legal regional wine. If a red wine performs well during the VDQS period, it can be upgraded to AOC level. In general, the label of a bottle of wine will be marked with "name+name of origin+vin dé limit é de qualité superieure".
(4) Legal place of origin
The full name of AOC is clamation d' origine Controllee, which is translated as the name of origin control and belongs to the highest grade of French wine. Only the red wine whose grape variety, planting quantity, brewing technology and alcohol content have been certified by experts can meet the AOC standard. In France, AOC production accounts for about 35% of the total wine production, and Bordeaux and Rhone Valley are the main producing areas of French AOC red wine. When buying red wine, you can pay attention to check whether the label of the wine bottle is marked with "title+name of producing area+controlled person/protected person", which is proof that the quality of red wine meets AOC and AOP standards.

How long can red wine be preserved after opening a bottle?
Under normal circumstances, it is best to drink ordinary wine within 4-6 hours after opening the bottle, and the longest time is no more than 24 hours. Once the wine left in the bottle comes into contact with air, the phenols that affect its taste will dissipate and the taste of the wine will become worse. Even if a bottle of wine has only been opened for a day or two, the taste of the wine has changed. Because the speed of change is very fast, even if it is only 24 hours, the difference is obvious. Wine that has been opened for two or three days will taste bad and can't be eaten. However, this is aimed at the situation of poor preservation after opening the bottle. If it can be properly preserved after opening the bottle, it can still be preserved for a long time. Don't drink too much, lest you waste it. It doesn't matter if you haven't finished it yet.
