Los Carneros

🔍 Quick Summary

Los Carneros AVA lies at the southern gateway of Napa and Sonoma, cooled by San Pablo Bay’s fog and breezes—perfect for crafting refined Pinot Noir, Chardonnay, and sparkling wines in a Burgundian style.

📜 History

  • First climate-defined AVA (1983): Los Carneros was the first U.S. appellation defined by its climate, not political boundaries.

  • Cross-county terroir: It spans Napa and Sonoma counties, with most of it in Sonoma.

  • Early revival: Vineyards were revitalized post-Prohibition, like Louis M. Martini’s 1940s replants.

🧠 What to Know

Cool, breezy, and delicately powerful:

  1. Fog & Bay Breezes: Marine cooling from San Pablo Bay enhances lengthy hang times and balanced ripening.

  2. Clay-Loam Soils: Thin, shallow yet moisture-retaining clay topsoils stress vines modestly, intensifying fruit.

  3. Varietal Focus: Pinot Noir and Chardonnay thrive here; also crucial for sparkling wine production.

  4. Emerging Reds: Merlot and Syrah are gaining recognition, especially in warmer pockets.

  5. “Napa’s Burgundy/Champagne”: Carneros is celebrated for both its elegant still wines and world-class sparkling offerings.
