Les Marnes Blanches

Pure, Terroir-Driven Wines from Sainte-Agnès, Jura

Les Marnes Blanches is a celebrated young domaine nestled in the village of Sainte-Agnès, just south of Lons-le-Saunier in the Jura region. Founded in 2011 by the skilled husband-and-wife team Pauline and Géraud Fromont, the domaine has quickly gained acclaim for producing wines that are precise, pure, and deeply expressive of their unique terroir.

A Philosophy Rooted in Respect for Nature and Minimal Intervention

From the very beginning, Les Marnes Blanches has been certified organic (Ecocert), with a strong focus on nurturing soil health and fostering biodiversity well beyond standard organic practices. The domaine’s name honors the distinctive white marl soils (“Les Marnes Blanches”) that shape the character of their vineyards, alongside other Jura soils like grey and blue marls.

Winemaking with a Light Touch

• Hand-Harvesting & Sorting: Grapes are carefully hand-picked and sorted to ensure quality.

• Spontaneous Fermentation: All wines ferment naturally with indigenous yeasts.

• No Fining or Filtration: Wines are left unfined and unfiltered to preserve their authenticity and texture.

• Minimal Sulfur Use: Sulfur additions are kept to an absolute minimum, often avoided altogether, to maintain purity.

• Aging: Wines mature primarily in older foudres and demi-muids, allowing slow development without overpowering oak influence.

Signature “Ouillé” Whites

Les Marnes Blanches is especially known for its “ouillé” style white wines made from Chardonnay and Savagnin. These wines showcase a crisp, fresh, and mineral-driven profile, highlighting the purity and precision of their Jura terroir without oxidative notes.

Classic Jura Varieties

Pauline and Géraud cultivate Jura’s traditional grape varieties, including Chardonnay, Savagnin, Poulsard, Trousseau, and Pinot Noir. Their wines, often crafted from select vineyard parcels, have become highly sought-after for their authenticity and refined expression of the region.
