Situated on top of the hill where the House of Lanson and its wine cellars are also located, Clos Lanson benefits from a distinctive microclimate and particularly chalky soil. The vineyard is treated just like a family garden due to its small size and the special care and attention that it has always received. This Clos Brut is a vintage Champagne whose juice, which comes exclusively from the first pressing, is vinified for several months in oak barrels.
