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 Merzoian – sister, sister-in-law, and wife to the owners.
