Champagne Éléonore — Blanc de Blancs Grand Cru from Oger
In the heart of the Côte des Blancs, on the clay-limestone slopes ofthe Oger Grand Cru, Éléonore embodies a vision of champagne that is resolutely unconventional. Founded in 1965 by Bernard Dzieciuck, the house is now run by his son Didier Dzieciuck, who takes the family philosophy to its logical conclusion: ‘I challenge, therefore I am’. Across 13 hectares of pure Chardonnay, including plots on the edge of woodland with a distinctive character, Didier cultivates individuality rather than conformity. The cuvées Gageure, Ambigramme, Mystère 9 and Buveur de Blancs are all enigmas presented to the taster — champagnes that challenge established conventions without ever compromising the excellence of the Oger terroir.

The Éléonore vintages — Gageure, Ambigramme, Mystère
The Éléonore range centres on Grand Cru Chardonnay in its purest form. La Gageure 22, a vintage cuvée, reveals the precision of a particular year and its pencil-and-flint minerality — ideal with sole meunière or pan-fried scallops.L’Ambigramme plays on the symmetry of its aromas – acacia blossom, candied citrus and hazelnut – making it perfect as an aperitif or with fine de claire oysters. Mystère 9 and Buveur de Blancs push the expression of the Oger terroir to its limits, pairing beautifully with shellfish or a seafood risotto; the Rosé de Saignée, meanwhile, pairs well with roast poultry or a platter of soft-set cheeses.
Served between 8 and 10 °C in a slightly flared barrel-shaped glass, the Éléonore cuvées benefit from being allowed to breathe for a few minutes in the glass before tasting. The vintage wines — led by Gageure 22 — have an ageing potential of 5 to 8 years, giving Oger’s Chardonnay time to develop its buttery character and deep minerality.

Éléonore — Oger since 1965: the challenge of Chardonnay
Bernard Dzieciuck laid the foundations for the estate in 1965 in Oger, an iconic Grand Cru commune in the Côte des Blancs. His vineyards, planted with Chardonnay on the Lutetian limestone of the Côte, passed into the hands of his son Didier Dzieciuck and Carole Tranchard, who represent the second generation. Together, they inherited a 13-hectare vineyard, certain plots of which, on the edge of the forest, lend the wines a unique aromatic complexity not found in more exposed terroirs.
At the helm of winemaking, Didier Dzieciuck champions an experimental approach based on personal observation rather than on Champagne dogma. Each harvest is an opportunity to challenge established assumptions, refine the blends and explore the limits of Oger’s Chardonnay — a unique grape variety, cultivated here without compromise or concession.

Your questions about Éléonore champagnes

Pépites en Champagne offers the full range — Gageure, Ambigramme, Mystère 9 — by the bottle or in gift sets, with up-to-date prices and express delivery included.
What food and wine pairings go well with Éléonore champagne?
Éléonore Blancs de Blancs are the perfect accompaniment to oysters, shellfish and fine fish (sole, turbot, sea bass en croûte). L’Ambigramme is superb as an aperitif or with blue-veined cheeses. The vintage Gageure 22 pairs well with truffle-crusted poultry or scallops on a bed of purée. The Rosé de Saignée is a natural choice with roast poultry or a red berry dessert.
How should Éléonore champagne be stored and served?
Store the bottles horizontally, at between 10 and 12 °C, away from light and vibrations. Serve at between 8 and 10 °C in a flared wine glass. Non-vintage cuvées are best enjoyed within 3 to 5 years of disgorgement; the Gageure 22 has an ageing potential of 5 to 8 years, allowing the Oger Chardonnay to develop its full, buttery maturity.

What sets the Oger terroir apart from the other Grands Crus of the Côte des Blancs?
Oger features deep Lutetian limestone with a slightly higher clay content than Cramant or Avize, giving the Blancs de Blancs a fuller texture and a rounded minerality rather than a sharp one. Wines from Oger are generally rounder than those from Avize, and more floral than those from Mesnil-sur-Oger. At Éléonore, the vineyard plots on the edge of the woods further accentuate this distinctive aromatic complexity.
What is the flavour profile of Éléonore champagnes, and how do they stand out?
The Éléonore vintages embody the classic character of Oger’s Grand Cru Chardonnay: white flowers, candied citrus, fresh hazelnut and chalk. Didier Dzieciuck’s experimental approach introduces more distinctive notes depending on the vintage — a briny edge, a long mineral finish — with carefully controlled dosages that allow the terroir to express itself without residual sugar masking the wine’s character.
