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.

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.
