Cotes de Thongue? If I were to get something from the Languedoc, I’d be more inclined to choose a viogner or a marsanne roussanne mix. Too much sun does something to chardonnay that doesn’t ring right IMO. Chardonnay from other regions can be so much better, my preference would be something eastern, a cotes de jura for instance.
Saying that, the best white from around these parts (again IMO, it’s so subjective) is an odd beast of chardonnay, viogner, manseng and chenin (not exactly local varieties the last two)
