A twist in Champagne: Chardonnay Rosé has officially been added to the list of grape varieties permitted by the appellation’s rulebook, joining the three historic mainstays — Pinot Noir, Meunier, and Chardonnay — as well as the four lesser-known varieties: Arbane, Petit Meslier, Pinot Blanc, and Pinot Gris. A natural mutation of Chardonnay Blanc, already listed in the French Catalogue since 2018, this extremely rare variety is distinguished by its pinkish skin and a more intense, tropical aromatic profile. Compared to the classic version, it shows higher acidity, lower pH, and greater structure — traits that promise base wines with more tension, freshness, and complexity. Though more delicate to cultivate, it holds great potential and brings a breath of fresh air to a region that has always fiercely protected its traditions.
This is not the Comité Champagne’s first step toward innovation: last year, the experimental use of the Voltis grape variety was introduced. Voltis is a “Piwi” grape, naturally resistant to powdery mildew and downy mildew, and allowed in limited quantities — up to 5% of vineyard plantings and 10% of the blend. The goal, then as now, is to promote more sustainable viticulture that can better withstand climate change, without compromising the identity of the AOC. Through mutations, agronomic trials, and new “en rose” nuances, Champagne proves it can evolve while remaining true to itself — a laboratory where tradition is never static and the future is crafted in the glass.
What Is Chardonnay Rosé, the Forgotten Grape of Champagne Now Included in the Rulebook
July 31, 2025, officially becomes a historic date for Champagne: it marks the day Chardonnay Rosé was formally added to the cahier des charges of the Champagne appellation as a main grape variety. This decision aims to enhance a unique genetic heritage, bringing back to light a forgotten grape deeply rooted in the region’s history.
First identified in the early 1900s between Champagne and Burgundy, Chardonnay Rosé is, as mentioned, the result of a natural mutation of Chardonnay Blanc. Preserved by generations of passionate winegrowers, it survived until recently only in ampelographic collections or as rare scattered vines. Its inclusion in the French Catalogue in 2018 allowed it to be officially recognized as a distinct variety, paving the way for its reintroduction into Champagne’s vineyards.
Unlike lab-created varieties such as Voltis, Chardonnay Rosé is a “facétie de la nature” — a spontaneous gift that reflects Champagne’s ability to intelligently adapt to today’s climatic challenges. Its agronomic and organoleptic characteristics are similar to those of Chardonnay Blanc, but the slight pigmentation of its skins and its more pronounced aromatic notes offer new opportunities for refined and original winemaking interpretations.
Though it represents only a tiny fraction of the vineyard — just 0.5% alongside other minor varieties — its inclusion in the rulebook underscores Champagne’s deep commitment to genetic diversity and the vegetal memory of its terroir. In an era where sustainability and climate adaptation are key to the evolution of viticulture, Chardonnay Rosé becomes a symbol of a virtuous balance between preservation and innovation.
