Cuvaison produces Chardonnay from Los Carneros, the cool-climate region that straddles Napa and Sonoma counties. The appellation's maritime influence and morning fog create conditions suited to the variety's ripening arc—balancing richness with acidity and complexity. The winery's Small Lot Estate Grown Chardonnay Hedon and Small Lot Coeurtina Estate Chardonnay represent focused expressions of vineyard-specific fruit, while the Adda Chardonnay offers a broader view of the estate's capabilities. These wines have been assessed by Wine Enthusiast, Wine Advocate, Decanter, and Wine Spectator. Los Carneros Chardonnay typically displays the region's signature character: citrus and stone fruit notes, mineral undertones, and the textural weight that cool-climate viticulture can impart.
