Founded in 1971 by Michel and Marie-Claude Jeaunaux (joined today by their son Cyril and his wife Clémence), the domain owns 4.5 hectares in Talus-Saint-Prix, in the north of Coteaux du Sézannais and in the south-west of Côte des Blancs, and 1 hectare in the Aube, in Côte des Bar, not far from Bar-sur-Aube. In Talus, on the fully south-facing, clay and chalk-rich slopes (with a rare presence of flint), the planting consists primarily of Pinot Meunier (60%) followed by Pinot Noir (30%) and Chardonnay (10%) and the vines are 40 years old on average. The Aube vineyards were planted between 2001 and 2003, with equal proportions of Pinot Noir and Chardonnay. Cultivation techniques follow organic practices closely and there is very little intervention in the cellar, allowing the different terroirs to express themselves as naturally as possible. Cyril Jeaunaux is a member of "Terres et Vins de Champagne" alongside winegrowers of the calibre of Pascal Agrapart, Francis Boulard, Benoît Laherte, Vincent Laval, Franck Pascal and Benoît Tarlant, to name just some. This domain is a very sound bet for champagne. The grapes are harvested by hand and pressed the traditional way before undergoing fermentation in oak barrels. Malolactic fermentation is prevented. The wines are then left to develop on the lees for six months. Served at 9°C, this champagne has a pale yellow colour, a fruity nose (apple, pear, citrus, white-fleshed fruit) and a mineral and fruity palate. It pairs beautifully with seafood. Drink within five years.

The Extra-Brut Sélection cuvée is the result of a blend of 60% Pinot Meunier, 30% Pinot Noir and 10% Chardonnay, a representative blend of the terroirs of Talus-Saint-Prix. The preponderance of Pinot Meunier brings fruitiness, and grapes selected from the most clay-rich soils, strengthening the wine's structure. The low dosage (5.5g/l) enhances the wine's sharpness and freshness.
