About the Alliance

Petaluma Gap Winegrowers Alliance represents the farmers and vintners whose devotion to the land has aided in crafting world-class wines from the Petaluma Gap.

Our Mission

The mission of the Petaluma Gap Winegrowers Alliance is to:

  • Promote the growers and vintners of the Petaluma Gap and foster the production of high-quality wines crafted from grapes grown in the Petaluma Gap American Viticultural Area (AVA).
  • 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.
