Offered for the first time since its completion in 2010, Failla Winery Estate presents a rare opportunity to acquire a fully operational, fully entitled winery and hospitality destination in one of Napa Valley's most desirable locations. The offering includes the real estate only; the Failla winery brand and business are not included. Situated on nearly 17 acres along Silverado Trail, the estate offers exceptional visibility, accessibility, and branding potential. A vineyard-lined drive leads to a historic farmhouse tasting room and an extraordinary underground cave winery and tasting room, creating an unforgettable visitor experience near two luxury resorts. Permitted for 10,500 cases annually under its 25,000-gallon permit, the property includes approximately 20,641 square feet across six structures. The centerpiece is a 13,276-square-foot underground cave featuring production facilities, barrel and library storage, private tasting rooms, and hospitality spaces. Additional improvements include a 4,020-square-foot crush pad, barrel storage barn, pump house, and a residence currently serving as a second tasting venue. Expansion plans could allow the cave to grow to approximately 27,225 square feet while increasing permitted production capacity to 33,000 cases annually. Located in the prestigious St. Helena AVA, the estate features a prolific well producing approximately 200 gallons per minute, 3.5 acres of head-trained, dry-farmed Zinfandel, and the potential for approximately three additional vineyard acres, subject to approvals. The underground cave is one of the property's greatest assets. Replicating a fully entitled cave winery and tasting room of this scale today would require years of permitting, complex engineering, and substantial capital investment. A buyer acquires a turnkey production and hospitality facility while avoiding the time, cost, and entitlement risks of new construction. Beyond its replacement-cost advantage, the cave provides naturally stable temperatures ideal for barrel aging, wine storage and production, and reducing energy and climate-control costs while helping protect valuable inventory. The unique cave wine tasting setting enhances premium hospitality and creates a distinctive destination that is increasingly difficult to replicate in Napa Valley. Purpose-built winery estates of this caliber rarely become available, offering an exceptional combination of location, infrastructure, operational efficiency, and value.
