Champagne Bourgeois-Diaz

is a small, artisan Champagne house located in Crouttes-sur-Marne in the Vallée de la Marne region of Champagne, France. It is run by Jérôme Bourgeois (4th generation) alongside his partner Charlotte. The estate spans around 6.5–7 hectares of vines and follows certified organic and biodynamic viticulture.

Founders & Background

  • Jérôme Bourgeois was born in 1977 into a family of winegrowers and took over the family estate in 2001.

  • Charlotte (his partner) joined the estate in 2016 and plays a key role in the brand and winemaking.

  • Although rooted in tradition, the estate emphasises a modern and ecological approach to viticulture and cellar work.

Terroir, Vineyards & Viticulture

  • Vineyard size: Around 6.5–7 ha, planted with approximately 3.5 ha Pinot Meunier, 2 ha Pinot Noir and 1–1.3 ha Chardonnay.

  • Soils: Clay-limestone (argilo-calcaire) soils typical of the Marne valley.

  • Age of vines: On average around 35-40 years old.

  • Farming: Converted to organic/ biodynamic farming, certified with Demeter standards (from around 2015). No synthetic herbicides/fungicides are used; the estate emphasises biodiversity and hand-work in the vineyard.

  • Winemaking: Grapes are pressed using a traditional “Coquard” press (labour-intensive, very gentle extraction). Fermentations use indigenous yeasts; minimal or no added sulphur; each parcel and grape variety is vinified separately; aging on lees for extended periods in various vessels (steel, wood, concrete).

Style & Wines

The wines of Bourgeois-Diaz aim for purity, terroir-expression and vitality rather than heavy dosage or obvious house style. Key characteristics & cuvées include:

  • BD’3C “Trois Cépages” – Blend of Pinot Meunier, Pinot Noir and Chardonnay; aged on lees; Brut Nature.

  • BD’M (100% Meunier) – A pure expression of Pinot Meunier from older vines, from clay-limestone soils; aged on lees; Brut Nature.

  • BD’N Blanc de Noirs – Primarily Pinot Meunier (with some Pinot Noir); dry, mineral, elegant.

  • BD’B “Le Temple” Blanc de Blancs – 100% Chardonnay from a single plot “Le Temple”; clay/chalk soils; aims for finesse and tension.

  • Les Bien Aimées (2018 vintage) – Example of a single-vintage parcel cuvée aged under cork; relatively rare.

  • Les Justices (2018 vintage) – Another high-end single-parcel cuvée.

In general their wines are:

  • Brut Nature or Extra Brut (very low or no dosage)

  • Very low added sulphur (or none)

  • Minimal filtration/fining (in many cuvées)

  • Emphasis on terroir and vintage rather than standardisation

Significance & Unique Aspects

  • Bourgeois-Diaz is part of the “grower-Champagne” movement: small scale, estate-grown, terroir-focused, minimal intervention, in contrast to large commercial houses.

  • Their commitment to biodynamics in a region still relatively using conventional methods makes them stand out.

  • The use of older vines, clay-limestone soils and a mix of grape varieties (with emphasis on Pinot Meunier, which is often undervalued in Champagne) gives their wines a distinctive character.

  • The traditional press, separate parcel vinifications, extended lees ageing and very low dosage all contribute to wines that reward time and show complexity, texture and minerality rather than simply immediate fruitiness.

  • Because production is limited and philosophy very craft-oriented, their bottlings tend to be highly sought by aficionados of artisan Champagne.

Practical Info

  • Location: 43 Grande Rue, 02310 Crouttes-sur-Marne, Champagne, France.

  • Vineyard size: ~6.5–7 hectares.

  • Grape varieties: Primarily Pinot Meunier, Pinot Noir, Chardonnay; small amount of Pinot Blanc in some references.

  • Certified organic & biodynamic (Demeter) since around 2015.

  • Style: Estate-grown Champagnes, Brut Nature/Extra Brut, limited dosage, minimal intervention.

  • Visitors: As a smaller estate, visits / tastings likely by appointment—important to contact ahead if interested.
