Pinot Noir has the largest planted area among the grape varieties in France’s Champagne wine region.
The three principal Champagne grapes are Pinot Noir, Pinot Meunier, and Chardonnay. Pinot Noir is especially important in the Montagne de Reims and the Aube, where its structure and depth suit the region’s cooler conditions and chalky vineyard sites. Pinot Meunier is strongly associated with the Vallée de la Marne, while Chardonnay is particularly prominent in the Côte des Blancs.
Planting proportions can change as vineyards are replanted, but Pinot Noir has historically held the largest share of Champagne’s vineyard area. Exact percentages therefore depend on the year and source.
This is different from asking which grape is most famous in a particular subregion. Chardonnay dominates the Côte des Blancs, while Pinot Noir leads the overall regional planting picture.
