The term is precise: a "blanc de blancs" champagne is produced exclusively from white-berried grape varieties. While Chardonnay is the most iconic of this category, the Champagne AOC also authorizes four other varieties: Petit Meslier, Arbane, Pinot Blanc, and Pinot Gris. These historic and rare grape varieties are very limited today, together representing less than 0.3% of the Champagne vineyards.
In practice, 100% Chardonnay champagne is the standard. It is what defines the style: tension, freshness, and minerality. The other white grape varieties appear in niche cuvées, often in blends, to provide a unique signature, such as the smoky notes of Petit Meslier or the floral finesse of Arbane.
The AOC rule is simple: as soon as a black grape variety is included in the blend, the champagne can no longer claim the Blanc de Blancs designation.
