Founded in 1856, this Registered Historic Landmark is among the oldest wineries in California. Dedicated to making the finest Zinfandels that express the true character of the vineyard for which it is named. The Sobon family pioneered the planting of Rhône varietals in the foothills, and all grapes are organically grown. The winery is also the site of the Shenandoah Valley Museum of early agriculture and winemaking and one of the prettiest picnic areas in the county.
