Champagne Blanc de Chardonnay by Chavost is the result of 100% Chardonnay from grapes grown on the Domaine's 5 hectares of vineyards in Chavot-Courcourt, a commune of south of Epernay in the Vallée de la Marne, which have been officially converted to organic farming. 

The cuvée is made only from the juice of the first pressing (tête de cuvée) and among its special features is the use of concentrated grape must during the vinification process.

Vinified 100% in temperature-controlled stainless steel vats, this Champagne has no added sulphites, and it is characterised by spontaneous alcoholic fermentation and malolactic fermentation through the use of indigenous yeasts and bacteria.
