Overview

A rare opportunity to restore Napa Valley's last unrestored pre-Prohibition winery. Located along Conn Valley Road, this historic 1870 stone-and-redwood winery is one of only 42 pre-Prohibition winery structures in Napa Valley and the only believed to remain within its original 19th-century context. While requiring extensive renovation, the three-story, +/- 13,034-square-foot stone winery features milled redwood beams, twenty hand-hewn arched doors and windows, and 300 feet of frontage along Conn Valley Road. The property benefits from a permanent, transferable Napa County winery use permit allowing 20,000 gallons of production, 120 visitors per week, 19 events annually, and a full commercial kitchen a highly uncommon entitlement combination. A 2,200 sq. ft. historic barn is permitted for office and flexible use. Conceptual site plans have been approved, with infrastructure in place including a developed water source, approved wastewater system, completed percolation testing, and three-phase power available adjacent to the site. Set on approximately +/- 2 acres in a quiet rural corridor just minutes from St. Helena, Meadowood Resort and Lake Hennessey, and surrounded by some of Napa Valley's most acclaimed estates. Offered unrestored and unbranded, this property presents a singular opportunity to revive an authentic Napa Valley winery with irreplaceable historic and entitlement value.
