Champagne Diebolt-Vallois is a family-run domaine based in Cramant, with roots going back to the early 20th century. The house was formed by the union of Jacques Diebolt, from Cramant, and Nadia Vallois, from Cuis. Both families have long-standing connections to winegrowing—Nadia’s lineage traces back to 16th-century growers in Cuis, while the Diebolt family, originally carpenters from Alsace, settled in Cramant in 1871. Jacques’ maternal grandfather was a grower, and it was under his guidance that Jacques began working in the vines.

The first Diebolt-Vallois harvest took place in 1959. Since then, the domaine has expanded its vineyard holdings and production, now covering parcels in Cramant and Chouilly (both Grand Cru), Cuis (Premier Cru), and Epernay. While the estate holds NM status, the fruit still comes exclusively from family-farmed vineyards, including those inherited through the Vallois side.

Today, the third generation is actively involved. Arnaud and Isabelle, children of Jacques and Nadia, manage the domaine, supported by their own children: Ophélie, Philippine, and Guillaume—all of whom are formally trained in viticulture and oenology. Three generations now contribute to the domaine’s evolution.

The range is largely Chardonnay-focused, with most cuvées sourced from the chalky slopes of the Côte des Blancs. The domaine’s approach respects the identity of each terroir. In Cramant, the wines tend to be creamy, mineral, and balanced, while Cuis contributes freshness and structure, especially from its higher-acidity plots. Vinification is carefully managed: fermentation at 15°C in stainless steel or neutral oak, with parcel-by-parcel vinification and blending only at the final stage. Malolactic fermentation is used selectively depending on the vintage, and never for the prestige cuvée Fleur de Passion.

Fleur de Passion is made from 100% Chardonnay from the oldest vines in Cramant (55–75 years old), fermented in used Burgundy barrels, aged at least seven years on lees, without malolactic fermentation or filtration. It was first produced in 1995 and remains a vintage-only cuvée made in limited quantities.

Though known for Chardonnay, the entry-level Tradition cuvée includes Pinot Noir and Meunier, reflecting the domaine’s holdings outside Côte des Blancs. Sustainable viticulture is central to the estate’s philosophy: no pesticides or insecticides have been used for over two decades, and while not certified organic, they follow lutte raisonnée to allow flexibility in challenging vintages.

Diebolt-Vallois exports about 80% of its production, with strong markets in Scandinavia and Italy. In France, distribution is focused on restaurants, hotels, and independent wine shops.
