The Languedoc was known for a long time as the wine lake of France. The region was the main source of very simple wine, often Vin de France. Luckily, things have changed considerably. Winemakers have become aware of the fact that quality is important if they want to gain respect and sell their wines at a higher price. The evolution in the Languedoc to a tiered system with the AOC Languedoc as the basis, with communal AOCs in the middle and Crus at the top of the pyramid, is one of the things that shows how the region is focusing more and more on quality. Things are changing at a fast pace : Terrasses du Larzac was promoted to cru status in 2014, so was La Clape in 2015, and Pic St Loup was the latest to join in 2017. Earlier sub-regions to have become Languedoc crus were Roquebrun and Berlou (Saint-Chinian), La Livinière (Minervois) and Boutenac (Corbières).
