Owner: Mendocino Wine Company. MWC owns the Parducci winery (this is not a certified organic brand) but not the vines.

History: Adolph Parducci, a Californian of Tuscan descent, established Parducci Wine Cellars with his wife Isabella in 1932. Adolph had arrived in Northern California with his parents in 1912, aged 16. In 1921 Adolph purchased his first vineyard, the Parducci Home Ranch in the Ukiah Valley. In 1932, Adolph and his four sons built a winery. One of the sons, John Parducci (1918-2014) kept the wine grape flame flying in Mendocino after Prohibition when few others were prepared to grow grapes.

The Parducci family sold the winery in 1976 to the Newport Beach-based Teachers Management and Investment group, but continued to be active in the business until 1994 (when the Teachers group forced him out. John and his wife Margaret then bought the Zellerbach winery southwest of Ukiah and renamed it McNab Ridge winery. In 1996, investor Carl Thoma purchased Parducci Wine Cellars and, eight years later, sold it to the current owners, Tom and Tim Thornhill of Mendocino Wine Company. The Ukiah-based vineyard covers about 100 hectares (250 acres) and produces around 200,000 cases of wine a year.
