An important development in the source of Domaine Carneros’ fruit came in 1991 with the acquisition of the Pompadour Vineyard, situated on the western side of the Carneros appellation. This vineyard consists of 58 acres of Chardonnay and Pinot Noir vines first planted in 1991 on dense clay, clay loam and sandy soils with a gently sloping topography. The Pompadour vineyard contributes to the blend of both the sparkling and still wines.
