Why don’t they make more ”vin de cepage” in France? Or put the grape variety on the label?

You often hear the critique “Why don’t the French make more wines with the grape variety on the label? It would be so much more easy to understand!”. Well, maybe for some: A survey has shown that only 42% of the French claims to have heard of the concept “vin de cepage” (wine sold under the grape variety name) and only 15% could give a correct example of such a vine. The most common grape varieties cited were: Merlot (named by 3.6% of the respondents), Cabernet (2.8%), Chardonnay (2.1%) and Gamay (1.9%). All according to La Journée Vinicole.
