Which AVA overlaps Napa and Sonoma?

Which AVA overlaps Napa and Sonoma?

• A. North Coast AVA
• B. Napa Valley AVA
• C. Carneros
• D. Stags Leap District

Answer: (C)

AVAs can cross political borders, and Carneros is the one that sits across the boundary of Napa and Sonoma counties. The Los Carneros AVA runs along the southern ends of both Napa Valley and Sonoma Valley, so vineyards labeled Carneros can come from either side of the county line. This cooler, bay-influenced climate is ideal for varieties like Chardonnay and Pinot Noir, which helps explain why this cross-border designation is notable. In contrast, Napa Valley AVA lies entirely within Napa County, and Stags Leap District is a Napa sub-AVA, while the North Coast AVA is a larger region that includes parts of both counties but isn’t defined by a single cross-border location in the same way.
