Maison Louis Jadot bought the Château Des Jacques estate in 1996. It is situated in Moulin-à-Vent, between Fleurie and Chénas and has 28.78 hectares of Moulin-à-Vent vineyards. Of this, there are 6 individual 'clos' which cover an average of 19.5 hectares. The Moulin-à-Vent wine is now referred to as the 'King of Beaujolais' and is considered to be the most Burgundian Cru of Beaujolais.

Geological origin and soil composition in Beaujolais are quite different from the Côte d’Or. This is why the Beaujolais red wines are only made of Gamay grapes. The soil of Clos du Grand Carquelin is quite light, made up of sand and a little bit of clay, lying on a bedrock high in manganese. This helps give the wine its deep colour. The vineyard covers 4 hectares, and once a proportion of the grapes have been de-stemmed, the wine is vinified in closed vats, and then aged in oak barrels for 12 months.
