The 18-hectare Les Clous is a small parcel of vines (‘climat‘) which often shows more depth than a Premier Cru. The word Clou is an old French word for Clos, used to describe a walled vineyard. It is located at the top of the Meursault on brown limestone soil overlying Jurassic marls with a very shallow white topsoil (40-50 cm). This soil-type gives tight, lively minerally wines. The vines are 30 years old with yields of 45hl/ha.
Since 2002, Jean-Claude Boisset has transformed Boisset from a traditional negociant into a viniculteur, a cross between a viticulturalist and a winemaker. He hired Gregory Patriat, one of the best of the younger generation of viticulturalists/winemakers to revitalise the J.C.Boisset wines. Gregory had spent the previous three years working in the vineyards at Domaine Leroy, and still spends a great deal of his time in the vineyards. He pays the growers by the hectare, rather than by yield, in order to ensure low yields. He also prefers to work with organic growers, as he finds they produce better fruit. Unlike other Burgundian negociants, who tend to blend from a large area or appellation, he specialises in making wines from `lieu-dits` or tiny plots of vines, something which accounts for the limited production of most of his wines.
