We Are a
Community
From borrowing tractors and collaborating on wine projects to volunteering at our local non-profits, Sonoma County’s wine community is a tight-knit bunch. We like to give back and we like to get together…always over a glass of great wine.
Sonoma County is home to over 1,800 winegrape growers, many from multi-generational families who have been farming here for centuries. That makes for long-standing relationships and a community that cares about it’s land, businesses and people.

Winegrape growers volunteer approx. 12,830 hours per year
74% of winegrape farming businesses donate to charitable causes

Our Organization
We Are Educators
Sonoma County Winegrowers was established by local winegrowing families to nurture and protect sustainable agriculture for future generations. In order to achieve this goal, we educate. Here at home, we provide educational resources to local winegrowers in the form of expert panels and grower education meetings which connect the winegrowing community and allow agricultural best practices to continue to thrive in the region.
Of course, we also love to educate wine lovers everywhere about the diverse, sustainable and unique wines of Sonoma County.
Our Purpose
Mission & Values
The mission of the Sonoma County Winegrowers is to increase the value of Sonoma County winegrapes and to nurture and protect this agricultural resource for future generations.
Sonoma County Winegrowers are family farmers who work hard every day to produce high quality grapes that are the foundation for world class wines. We are dedicated to sustaining our land for future generations. We preserve the land where we live and work and the water and air that we share with neighbors. We actively support our communities and are proud to be a part of Sonoma County.
