France's Languedoc region claims a new grand cru and grand vin system will 'simplify' life for its consumers. The base appellation AOC Languedoc will sit at the bottom of a three tiered pyramid. Superior appellations including Minervois and St Chinian will be labelled Grands Vins du Languedoc.The best vineyard sites such as Minervois La Liviniere and Corbieres Boutenac will be able to use the highest rating: Grands Crus du Languedoc. The appellation's trade association the CIVL said the idea was to make the system easier to understand.
