Blanc de Blancs Champagnes are made exclusively from white-skinned grapes and are most closely associated with Chardonnay, the variety that has found in Champagne one of its most emblematic homes. The Côte des Blancs, south of Épernay, is the best-known reference point for this style, thanks to its chalky soils and the presence of some of the region’s most important villages. A Blanc de Blancs, however, is not necessarily produced in the Côte des Blancs and does not by definition mean 100% Chardonnay: the term refers to the nature of the grapes used, while origin, variety and style can vary considerably.

Blanc de Blancs: what it means for Champagne

In the world of Champagne, the term Blanc de Blancs indicates a wine made exclusively from white-skinned grapes. It is therefore a category defined by the composition of the blend rather than by geographical origin or vineyard classification. Chardonnay is by far the most commonly used variety, but the appellation’s regulations also allow other white grapes, though they cover very small areas. The term can appear on Champagnes of different origin, vintage, dosage and length of ageing: very different interpretations can therefore lie behind the same name.

Chardonnay and the other white grapes

Chardonnay is the undisputed star of Blanc de Blancs and the benchmark grape for the style. In Champagne it brings freshness, finesse and a pronounced ability to age, with aromas that can recall citrus, white flowers and pale-fleshed fruits. Alongside Chardonnay, other white varieties are authorised: Arbane, Petit Meslier, Pinot Blanc, Pinot Gris and, from 2025, also Chardonnay Rosé. These are overall still very rare within the appellation, but they represent an interesting part of Champagne’s ampelographic history and are used by some producers to create cuvées with distinctive characteristics.

Where Blanc de Blancs Champagnes are born

The Côte des Blancs is the area most closely associated with Blanc de Blancs Champagnes. It lies south of Épernay and includes villages such as Chouilly, Cramant, Avize, Oger and Le Mesnil-sur-Oger, where Chardonnay is the dominant variety. The presence of the craie, the limestone chalk typical of Champagne, helps create favourable conditions for the vine and is one of the most recognisable elements of the terroir. Champagnes from this area are often marked by freshness, tension and good ageing potential.

However, the Côte des Blancs is not the only part of Champagne where Blanc de Blancs are produced. Chardonnay is also found in other areas of the region and can yield different expressions depending on soil, exposure and climate. In the Montagne de Reims, for example, the communes of Villers-Marmery and Trépail are particularly linked to Chardonnay. The Côte de Sézanne, to the south-west of the Côte des Blancs, also has a significant presence of the grape, while in the Aube, particularly around Montgueux, Chardonnay finds suitable conditions and contributes to a Blanc de Blancs map that is far broader than the Côte des Blancs alone.

The profile of Blanc de Blancs Champagnes

Chardonnay tends to give Blanc de Blancs a sense of freshness, drive and finesse. In younger versions, aromas of lemon, grapefruit, green apple, pear and white flowers generally come to the fore. Depending on the terroir and winemaking choices, chalky, saline and mineral nuances may also appear, particularly evident in Champagnes from limestone soils. Over time, the aromatic profile becomes more complex and can develop notes of dried fruit, honey, brioche and pastry. Freshness nevertheless remains one of the key elements in the balance of this style.

Ageing and evolution of Blanc de Blancs

The acid backbone of Chardonnay allows Blanc de Blancs to handle long ageing well. With time on the lees and subsequent bottle age, the fresher, citrusy aromas gradually give way to a broader range of sensations: dried fruit, toasted bread, brioche, honey and gentle spicy notes. The pace of evolution depends on the cuvée, the vintage, the terroir and the producer’s choices, so not all Blanc de Blancs follow the same path. Younger versions can lean into vivacity and floral-citrus components, while Champagnes subjected to longer ageing can develop greater complexity and depth.

At the table with a Blanc de Blancs

The freshness and aromatic profile of Chardonnay make Blanc de Blancs particularly well-suited to seafood cuisine. Younger versions can accompany oysters, crustaceans, mollusks and raw fish, while more mature and structured Champagnes can support more elaborate fish preparations, risottos and dishes with delicate sauces. White meats and certain cheeses can also pair well with this style. The choice of pairing depends above all on the cuvée’s style: a fresh, young Champagne calls for more delicate dishes, while an evolved Blanc de Blancs can stand up to preparations with greater aromatic complexity.
