Mendocino Winegrowers Inc. (MWI) is an alliance of grape growers and vintners working together to promote the grapes and wines from Mendocino County. The group was formed in 2012 to promote the quality and image of Mendocino grapes and wine with three target audiences: 1) decision-makers who buy grapes, 2) press and trade groups who write about, sell, or recommend wine, and 3) consumers who buy wine. MWI is run by the Executive Director, Bonnie Butcher, and a volunteer Board of Directors.
