Sonoma County is California’s most geographically and stylistically diverse wine region, stretching from the cold Pacific coast to warm inland valleys. While often overshadowed by neighboring Napa Valley, Sonoma has earned its own stellar reputation for producing world-class wines with a more relaxed, agricultural character. From fog-shrouded Pinot Noir vineyards to sun-drenched Zinfandel, Sonoma offers something for every wine lover.
A Patchwork of Climates
What makes Sonoma exceptional is its dramatic diversity within a relatively compact area. The Pacific Ocean’s cooling influence penetrates deep into the county through gaps in the coastal mountains, creating a patchwork of microclimates. This allows Sonoma to excel with both cool-climate varieties like Pinot Noir and warmer-climate grapes like Zinfandel and Cabernet Sauvignon.
Key AVAs
Sonoma contains 18 distinct AVAs, each with unique characteristics:
- Sonoma Coast - Cool, maritime-influenced, exceptional Pinot Noir and Chardonnay
- Russian River Valley - Fog-cooled, famous for elegant Pinot Noir
- Alexander Valley - Warmer, producing rich Cabernet Sauvignon
- Dry Creek Valley - Heritage Zinfandel territory
- Bennett Valley - Cool climate, excellent Pinot Noir
- Sonoma Mountain - Elevated sites with excellent drainage
