Mendocino Winegrowers, Inc.

Mendocino Winegrowers, Inc. Mendocino WineGrowers Inc (MWI) is an alliance of grape growers and vintners working together to promote the grapes and wines from Mendocino County.

Mendocino County’s authentic “green” credentials are unsurpassed by any other wine region in the world. The region is dominated by family farmers, many of whom have lived for two or more generations on their land—some tracing their roots to the first settlers in the 1850s. The entire farming community has a rare appreciation of the connection between man and earth. These farmers, grape growers and

winemakers among them, were at the forefront of the sustainable, organic, Demeter certified Biodynamic®, and Fish Friendly farming movement long before it gained the attention of the general population. “America’s Greenest Wine Region” is not a marketing slogan: it is the true reflection of all that this vast and varied county offers those who seek healthy foods and beverages and accessible yet pristine travel destinations.

Thank you to everyone who joined us at McNab Ranch on May 21 for the launch of Mendocino's One Block Challenge! It was wonderful to see growers, winemakers, and media partners come together around something we all care about: the long-term resilience of our industry.

Mendocino County has always led the way on sustainable farming, and the One Block program builds on that legacy. At its heart, it is about growing a local community of practice around regenerative viticulture, a flexible, soil-first approach focused on healthy soil and open to every grower, no matter your scale.

The Challenge officially kicks off with the next growing season, so keep an eye on our page for field days and ways to get involved.
Curious to learn more? You can explore the program through the Regenerative Viticulture Foundation at regenerativeviticulture.org, or send us a message here and we will be glad to help.
Stay tuned, there is more to come!
