History

Chateau St. Jean is a winery in Kenwood, California. The estate's Chateau dates to the 1920s: in 1916, Ernest and Maude Goff, who had established their family fortune in Michigan's iron ore mines and Pacific Northwest lumber, purchased approximately 300 acres in the Valley of the Moon area of Sonoma County, California. Construction on the Goff family's summer home – the Chateau – began in 1920, designed with solid oak banisters, an oak-paneled hallway, and a large oak fireplace in the living room, which now serves as the Reserve Tasting Room. White wine grapes grew on the property at this time, but with the onset of Prohibition, the family also planted prunes and walnuts. In the early 1970s, Ken Sheffield, and Bob and Ed Merzoian – San Joaquin Valley table grape growers and shippers – began a search for the perfect setting to build a premium California winery. The Valley of the Moon was their first choice and their attention focused on 250 acres of the Goff estate. Chateau St. Jean was founded in October 1973 and named after Jean Sheffield, who was the wife, sister, and sister-in-law of the three founders. Since 1973, the winery has been devoted to crafting elegant, site-specific wines that celebrate the character and prestige of Sonoma's most exceptional vineyards. The winery is led by winemaker Lisa Evich.
