About Us

For a Benovian, labor is life, and life is fulfilling. Winemaker and co-owner Mike Sullivan grew up tending his family’s vines on Sonoma Mountain. Proprietors Mary Dewane and Joe Anderson were both raised on hard work by their fathers, Ben Dewane and Novian Anderson. Hard work brings its own rewards, they would say. Be the best at what you do. Surround yourself with good people, and let them get to work. And never, ever produce anything that wouldn’t make you proud.

Here in the Russian River Valley, we are all part of a close-knit community that finds joy in purpose. We’re at our happiest during harvest, when friends join us on the sorting line and the winery and vineyards are buzzing with activity and camaraderie.

After years of humble, hard work, we believe that we are creating something truly beautiful that draws people together.
