The difference between red wine aoc and aop is as follows:

1, the difference between the red wine level AOP and AOC is the different versions of the French wine level grading system, the two mean the same thing, both refer to the legal appellations wines, which are the highest level of the French wine grade, while AOC is the old version, AOP is 2009 the new version after the reform.

2. At the end of the phylloxera crisis that swept across Europe, France saw an influx of counterfeit wines, and in response to this, the appellation regulations came into being and reached their heyday in 1923.

The Rhone Valley's Chateauneuf du Pape then took the lead in establishing the strict viticultural and vinification regulations that would become the prototype for France's later official classifications.

3. In the official classification system, AOC is the highest grade of French wines, occupying half of the total production; the next grade is VDQS (Very Good Quarterly Wine), which is a kind of transitional grade that will be upgraded to the AOC appellation, and at that time, the annual production was only 1%; the third grade is Vd, which is often translated as regional table wine; and the lowest grade is VdT, which is the daily table wine. The lowest grade was VdT, the everyday table wine.

4, the old classification in a long period of time are constraints on the production behavior of French wine farmers and producers, until 1992, the European Union formally established the PDO system, the purpose is to protect the agricultural products produced by the European Union countries. In response to the EU's reforms and in line with the European form of agricultural grade labeling.

France also carried out a reform in 2009, so the new AOP system replaced the original AOC system; the VDQS level was formally withdrawn in 2011, the original VDQS wines were either upgraded or downgraded; all the VdP and VdT wines were replaced by IGP and VdF respectively.
