Blanc de Blancs
Champagne made entirely from white grapes (Chardonnay).
What is Blanc de Blancs? Blanc de Blancs is a Champagne and sparkling-wine designation, French for "white from whites," that signals a wine made exclusively from white grapes. In Champagne AOC this means almost always 100% Chardonnay, with Pinot Blanc legally permitted but rarely seen outside niche bottlings such as Cedric Bouchard's La Boloree. The classic source is the Cote des Blancs, a chalky north-south strip south of Epernay whose east-facing slopes shelter the Chardonnay grand cru villages. The result is a leaner, more linear style of Champagne built around acidity, citrus, white flowers, and a distinctive chalky minerality.
Terroir and the Cote des Blancs
The Cote des Blancs runs roughly 20 km south of Epernay in the Marne department and covered 3,313 hectares (8,190 acres) as of 2006. Chardonnay accounts for around 95% of plantings here, and the region takes its name from the pale color of these grapes. The mostly east-facing slopes catch the morning sun, encouraging even, gradual ripening that preserves the acidity Chardonnay needs to shine in sparkling form.
Beneath the vines lies a thick chalk subsoil that drains heavily yet retains moisture during dry stretches, while also reflecting sunlight back onto the canopy. Six villages on the Cote des Blancs hold Grand Cru status — Avize, Chouilly, Cramant, Le Mesnil-sur-Oger, Oger, and Oiry — and supply much of the Chardonnay used in the vintage and prestige cuvees of the major houses. Cramant in particular is prized for elegant, airy Champagnes with creamy texture and a notably fine mousse.
Style, Aging, and How It Differs
Stylistically, a Blanc de Blancs leans bright and high-toned. Expect citrus, white flowers, stone fruit, and a chalky, mineral lift in youth, gradually building toward biscuit and brioche notes as time on lees adds richness. Alcohol typically sits around 12–12.5%, in line with Champagne as a whole.
Champagne AOC rules apply equally to Blanc de Blancs: non-vintage bottles must age a minimum of 15 months (12 of them on lees), and vintage cuvees a minimum of 36 months. The category is the natural counterpart to Blanc de Noirs, a white sparkling made from the black grapes Pinot Noir and Meunier, which tends to be broader and more structured. Outside Champagne, the term is occasionally used on other sparkling wines to indicate a 100% white-grape cuvee, almost always Chardonnay.
