What is one of the best kept secrets of Sonoma County winemakers?  The Petaluma Gap!

The Petaluma Gap is the gateway to the Sonoma Coast region. Although not yet a designated appellation, the Petaluma Gap is producing premium grapes that make the Sonoma Coast Appellation one of California’s best areas to grow primarily Pinot Noir, Chardonnay, and Syrah grapes.

The wind and the fog are the Petaluma Gap’s trademark. The “Gap” is actually a wind gap named after a coastal mountain opening that stretches east from the Pacific through the town of Petaluma and then roars south to San Pablo Bay.

The Petaluma Gap has a 150-year tradition of growing grapes. The Petaluma Gap Winegrowers Alliance is dedicated to supporting growing wine grapes and production of premium wines in the Petaluma Gap.

The Petaluma Gap produces wines for some of Sonoma County’s finest wineries including: Clary Ranch Winery, deLoach Vineyards, Flowers Vineyard and Winery, Hart’s Desire Wines, Kendall-Jackson Wine Estates, Kosta-Browne Winery, Landmark Vineyards, Loxton Cellars, Schug Winery, Schramsberg Vineyards, and Zepaltas Wines.


Our mission is to:

  • Promote the winegrowers and vintners within the Petaluma Gap and foster the production of high-quality wines crafted from Petaluma Gap fruit
  • Cultivate positive relationships with the community by elevating awareness of growing and winemaking practices and an understanding of the winegrowers’ commitment to respect and protect the land
  • Continue to advance Petaluma’s 150-year heritage as a successful wine-producing center


The Petaluma Gap is very proud to support and collaborate with the Sonoma County Winegrape Commission. The Sonoma County Winegrape Commission was established in 2006 as a non-profit marketing and educational organization dedicated to the promotion and preservation of Sonoma County as one of the world’s premier grape growing regions. With more than 1,800 growers, SCWC’s goal is to increase awareness and recognition of the quality and diversity of Sonoma County’s grapes and wines through dynamic marketing and educational programs targeted to wine consumers around the world.
