70% Chardonnay and 30% Pinot noir.
The Pinot Noir grapes come from Bisseuil (Côte des Noirs, premier cru) and the Chardonnay grapes belong to the parcel in Grauves (Côte des Blancs, premier cru).
The vineyard is composed of Chardonnay and Pinot Noir only. It is cultivated according to VDC and HVE norms. VDC stands for Viticulture Durable de Champagne meaning sustainable viticulture. HVE stands for Haute Valeur Environnementale meaning Environmental High Value.
Both labels require a respectful and ecological culture of the vines replacing chemical synthetic pesticides by natural ones. It also promotes biodiversity and the ecosystem of the vineyard. The tools and machines used in the vines are modern, kept to a minimum of interventions and chosen wisely in order to preserve the vine and the soil.
The grapes are pressed in pneumatic presses. Unlike mechanical presses, the pneumatic presses are specifically designed to be very gentle and use soft pressure on the grapes as not to choc them. The yeasts used for the fermentations are completely natural. More precisely, they are indigenous yeast ( from the terroir) and are cautiously selected for their optimal fermentation capabilities. A malolactic fermentation is realised on all Champagne Bonvalet wines, giving them a more supple and rounder finish. The corks are entirely made of natural cork and are supplied from European countries (Spain an d Portugal).
