Innovation runs in Mary and Michael Deere Colhoun’s family. The family tree includes John Deere, inventor of the steel plow that revolutionized farming. They seek to revolutionize winemaking at Landmark Vineyards with vintages designed to “enhance the joy of life.” They’ve extended the Sonoma experience to others with Friends of the Vineyard, a plan offering ownership of vineyard rows. And they bring the Landmark tasting experience to the city in Press Club, the new luxury wine bar on San Francisco’s Yerba Buena Lane. Of course, their Sonoma winery is easy to find—it’s the one with the vintage John Deere tractor parked out front.
