Champagne Chavost

Champagne Chavost is a Récoltant-Manipulant from Chavot-Courcourt in the Vallée de la Marne, south of Épernay, run by Fabian Daviaux. The village itself gives the house its name. Across 19 hectares, this is a Maison in transition: five hectares are farmed organically and biodynamically, while the remaining fourteen are still managed conventionally following raisonnée principles. What truly sets Chavost apart, however, happens in the cellar.

Vignoble & Terroir

The vignoble covers 19 hectares total in the Vallée de la Marne, split into two farmed blocks: 5 hectares are worked organically and partially biodynamically, 14 hectares conventionally following raisonnée principles. The vineyard plots lie in and around Chavot-Courcourt, south of Épernay. The exact cépage distribution isn't documented, but Meunier and Chardonnay play the leading roles in the lineup.

Viticulture & Sustainability

Chavost is AB-certified and works the 5 hectares of organic plots according to biodynamic principles. The remaining 14 hectares are farmed raisonnée. The approach aims for minimal intervention in the vineyard and maximum grape quality, which is then processed in the cellar with an equally purist philosophy.

Winemaking

The winemaking follows a uncompromisingly purist approach: spontaneous fermentation, complete malolactic fermentation, no added sulfur (Sans Soufre), no filtration, no fining. Aging takes place in stainless steel tanks and partially in light oak. All cuvées are bottled as Brut Nature (0 g/l dosage). This natural wine philosophy carries a higher risk for wine faults, which the Maison consciously accepts.

The Cuvées in Detail

Distinctly marked by autolysis: yeast, bread, dough dominate. Young and energetic, the mousse is edgy. Dégorgement 06/2025, aged without sulfur. The exact cépage composition isn't documented, Chardonnay and Meunier form the base.

Blanc de Chardonnay

Pure Chardonnay, spontaneously fermented and without sulfur. Non-vintage cuvée. The bottle I tasted showed the wine fault 'mouse': animal-nutty tones, dull-sweet finish, a known risk with sulfur-free wines.
