Editorial profile

Chateau St. Jean is a Sonoma Valley winery in Kenwood, built around a 1920s chateau constructed as the Goff family's summer home. Ken Sheffield and Bob and Ed Merzoian, table-grape growers and shippers from the San Joaquin Valley, founded the winery on part of the former Goff estate in October 1973, naming it for Jean Sheffield Merzoian.

The winery built its early production around single-vineyard designated wines drawn across Sonoma County's varied AVAs — Belle Terre and Robert Young for whites historically, and current bottlings from Benoist Ranch, Hallberg Ranch, Macaama Ranch, Mallacomes Vineyard and Oak Hill — alongside Reserve and 8555 tier Bordeaux-style red blends. The flagship is Cinq Cépages, a Cabernet Sauvignon-led Bordeaux blend drawing fruit from across Sonoma County. Lisa Evich is the winemaker.
