Petaluma Gap Wineries
About Petaluma Gap
Petaluma Gap is Sonoma's newest AVA (2017) and one of its most distinctive — defined by the wind corridor that funnels Pacific breezes through a gap in the coastal mountains. With fewer than 15 wineries, it offers a frontier-like discovery experience about 25 miles from the Golden Gate Bridge.
Petaluma Gap is Sonoma County's newest AVA, recognized in 2017 for its defining feature: a gap in the coastal mountain range that channels powerful Pacific winds directly into the growing area. These persistent winds stress the vines and produce grapes with intense flavor concentration.
The wind is so consistent that it's actually shaped the trees — you can see them permanently bent by the prevailing breeze. This extreme maritime influence produces Pinot Noirs of great intensity and structure, along with crisp Chardonnays and aromatic Syrahs that stand out for their cool-climate elegance.

Russian River Valley
Russian River Valley is one of California's premier cool-climate wine regions, best known for world-class Pinot Noir and Chardonnay. Pacific fog rolls through a gap in the coastal mountains each morning, creating ideal conditions for these varieties. Beyond wine, the region offers redwood forests, river recreation, and small-town charm.
Sonoma Valley
Sonoma Valley is the birthplace of California's commercial wine industry, dating to the 1850s. Flanked by the Mayacamas and Sonoma mountain ranges, it produces diverse wines across approximately 14,000 vineyard acres. The historic town of Sonoma and Jack London's home in Glen Ellen add cultural depth beyond wine.
Dry Creek Valley
Dry Creek Valley is Sonoma's Zinfandel heartland, with old-vine blocks that survived Prohibition still producing today. The compact 16-by-2-mile valley has a Bordeaux-like climate and remains refreshingly rural — family-owned wineries, no traffic lights, and the Dry Creek General Store (est. 1881) as its unofficial center.
Carneros (Sonoma)
Carneros straddles the Sonoma-Napa border and is defined by the cooling influence of San Pablo Bay, making it ideal for Pinot Noir and Chardonnay in both still and sparkling wines. It's the closest Sonoma wine region to San Francisco and home to iconic sparkling houses and world-class art.
