Napa, CA
Domaine Carneros is the only sparkling wine producer in the Carneros region that uses exclusively grapes grown within the Carneros appellation, which is defined by climate rather than political boundaries. The winery manages 195 acres across three vineyard sites, divided into 35 blocks that differ in rootstock, terrain, and clonal selection, allowing winemakers to blend a range of flavor profiles from estate‑grown pinot noir and chardonnay. Production emphasizes quality over yield, with small‑cluster clones, selective pruning, and sustainable practices such as mechanical weed removal, cover crops, and collaboration with the Napa Resource Conservation District to protect soil and local wildlife.
