Champagne Bourgeois-Diaz

is the passion project of Charlotte and Jérôme Bourgeois, a fourth-generation winemaking couple based in Crouttes-sur-Marne, in the heart of the Champagne region. Since taking over Jérôme’s family estate, they have transformed it into one of the region’s most respected biodynamic domaines.

Working across 7 hectares of vineyards, certified organic and Demeter biodynamic since 2015, their philosophy is deeply rooted in living soils, biodiversity, and lunar rhythms. In the cellar, their approach is low-intervention: spontaneous fermentations with native yeasts, minimal to no sulfur, and wines that are unfined and unfiltered.

Charlotte and Jérôme vinify each parcel separately, allowing the terroir to speak for itself. A traditional Coquard Champagne press ensures gentle extraction, and aging takes place in a thoughtful mix of vessels—stainless steel, oak barrels, foudres, amphorae, and clay eggs—chosen to enhance the character of each wine.

They cultivate Pinot Meunier, Pinot Noir, and Chardonnay across 20 plots, crafting elegant, expressive Champagnes. Their range includes single-parcel, single-varietal, and brut nature cuvées that reflect a pure, modern expression of Champagne—grounded in nature and guided by instinct.
