Hanzell Vineyards is a California wine producer located just outside the town of Sonoma. The winery was founded by James David Zellerbach (future United States Ambassador to Italy) who acquired 200 acres in the Mayacamas Mountains in 1943 and began planting Pinot Noir and Chardonnay in 1953. At the time, the entire state of California had fewer than 200 acres planted to Chardonnay.
