Hayfork Wine Co. In St. Helena is aptly named. John Lewelling, a horticulturalist, acquired the ranch in 1864 and six generations later his descendants are still working at vineyard management and winemaking. The historic Lewelling Ranch is one of the oldest family owned and operated agricultural enterprises in the region. Today Lewelling’s descendants are the Wight family, and Doug Wight runs a well-known vineyard management company. His daughter Haley, who grew up on the ranch, is winemaker for Hayfork, and Haley and her husband Erik Dodd run the winemaking business. The estate’s first Cabernet Sauvignon vintage was released in 2006. Hayfork also makes Grenache Blanc. All wines are produced in very limited quantities. Hayfork makes 300 to 500 cases annually.
