The Sonoma County Winegrape Commission, also known as Sonoma County Winegrowers (SCW), was established in 2006 as a marketing and educational organization dedicated to the promotion and preservation of Sonoma County as one of the world’s premier grape growing regions. SCW has oversight by California Department of Food and Agriculture which supports producer regions.

With more than 1,800 growers, SCW’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.

In January 2014, SCW committed to becoming the nation’s first 100% sustainable winegrowing region by 2019. As of September, 2019 99% of vineyards are certified by a third party auditor. These sustainability efforts were recently recognized with California’s highest environmental honor, the 2016 Governor’s Environmental and Economic Leadership Award (GEELA). Today, SCW continues our sustainability leadership with a new climate adaptation certification program. For more information, visit our sustainability page.

Our Team

Karissa Kruse

Karissa Kruse is President of the Sonoma County Winegrowers. She joined the organization as Director of Marketing in September 2012 and was named President for the organization on May 1, 2013.  Since taking over the top leadership role, Kruse has guided the strategy and implementation of Sonoma County’s commitment to become America’s first 100% certified sustainable wine region. Her forward thinking approach has helped Sonoma County Winegrowers gain global recognition for their efforts and she’s been invited to speak at major conferences around the world.

To continue to lead in the social responsibility component of sustainability, Kruse announced the relaunch of the Sonoma County Grape Growers Foundation in January 2016 that aims to assist local agricultural employees and their families in the areas of healthcare, affordable housing, childcare, education and workforce development. She currently serves as executive director of the Foundation.

In January of 2017, Kruse launched the Sonoma County Center for Ag Sustainability, a think tank in partnership with the Wharton School of Business, that is focused on bringing subject matter experts from around the United States to Sonoma County to work on issues and opportunities affecting the long-term preservation of agriculture.

In January of 2020, Karissa announced that Sonoma County Winegrowers is the exclusive partner with the California Land Stewardship Institute to launch a Climate Adaptation Certification, a first of its kind for agriculture. This exciting initiative will move beyond best practices in healthy soils to analyze the whole farm and implement climate friendly farming practices that minimize greenhouse gas emissions and increase carbon sequestration, which vary by soil type and microclimate.

Karissa earned a BS in Economics and an MBA in Marketing from Wharton School of Business at the University of Pennsylvania. She has 20 years of experience in various aspects of marketing, brand management, strategic planning and business development. Karissa has worked for companies such as General Mills, Universal Studios, Mattel and Dairy Management. She is a partner in a small winery, Argot Wines, and the owner of a 12-acre vineyard on Sonoma Mountain.

Kruse is on the Alumni Advisory Board for Wharton’s Initiative on Global Environmental Leadership and a member of the Global Wharton Women in Leadership. Karissa is on the German Marshall Fund Alumni Leadership Council and FIVS Global Environmental Sustainability Working Group. She is on the Board of Directors, Executive Committee and Housing Task Force for the Sonoma County Alliance. Karissa is on the Board of Directors, Board Development Committee and Women’s Leadership Council of the United Way of Wine Country and past Board Chair. She is on the Board of Directors of Sonoma County Tourism, Sonoma County Harvest Fair and Health Action Council. In 2020, Karissa joined the Board of Directors for the California Association of Winegrape Growers and First 5 Sonoma County.

In 2014, Kruse was selected as a North Bay Business Journal Women in Business Award recipient and was a Forty under 40 Award recipient in 2012. Kruse was honored with the Marshall Memorial Fellowship in 2015. Karissa received the 2016 Friend of Agriculture Award from the Sonoma County Harvest Fair. She was named to the 2016 and 2017 Wine Business Monthly Magazine’s Top 50 Wine Industry Leaders. In 2017, she was named to the Organic Authority’s List of “Badass Disruptors Changing Your Food System” and Food and Wine Magazine named her one of the most Innovative Women in Food & Drink. Karissa was honored by the North Bay Business Journal in 2017 with a Community Philanthropy Award. In 2018, Karissa was named A Green Leader by Wine Enthusiast and selected as the Leader of the Year by the California Association of Winegrape Growers.
