An exceptional opportunity to acquire the operational heart of Four Sisters Ranch & Winery, the 61.2± acre Silver Property combines an extraordinary collection of residential, hospitality, winery and agricultural assets. Improvements include a 3,140± sq. ft. adobe residence with 3 bedrooms and 4 baths; a 4,500± sq. ft. tasting room/winery facility with 2 baths, production space, lab and temperature-controlled barrel storage; a 3,000± sq. ft. event center with restrooms; and approximately 4,000± sq. ft. of additional winery and agricultural support space including temperature-controlled case storage, dry storage, workshop and equipment storage. Privately situated behind its own gated drive, the residential compound features a central courtyard, soaring wood-beamed ceilings, adobe fireplace, Viking-equipped kitchen, wine cellar, pool, tennis court and orchard. A detached 4-car garage includes dedicated office space and a full bath. The hospitality grounds offer expansive outdoor seating, pergolas with fire pits, bocce ball, horseshoes, bandstand, outdoor kitchen with pizza oven, event lawn and abundant parking. A separate bridal suite with half bath supports the event venue. The property has hosted weddings, corporate events, wine club gatherings, nonprofit events and private celebrations. Winery infrastructure supports approximately 23 tons of on-site processing and bottling, with approximately 200-barrel temperature-controlled storage plus additional temperature-controlled storage for approximately 2,000 cases. Approximately 43.78 acres are planted to Cabernet Sauvignon, Syrah, Zinfandel, Malbec, Tempranillo, Grenache and Petit Verdot, with 38.6± acres of mature Cabernet currently undergoing phased removal, offering significant redevelopment potential. The adjacent 155± acre Opal Property, with approximately 113 planted vineyard acres, is also available separately, providing an exceptional opportunity to substantially expand vineyard production while leveraging the Silver Property's established winery and hospitality infrastructure.
Property is moderate renovation needed.
Built in 1979, the property is well-maintained but shows its age. The kitchen and bathrooms feature dated finishes, including tile countertops and older cabinetry styles likely renovated 20+ years ago. The presence of a window AC unit in the office suggests the HVAC systems may not be fully modernized.
The estate is a fully operational business hub featuring a tasting room, a 3,000 sq. ft. event center, and complete production facilities capable of processing and bottling 23 tons of fruit on-site.
The property includes a unique 3,140 sq. ft. authentic adobe home with high-end amenities, including a resort-style pool, tennis court, and a private wine cellar, all set behind a private gated drive.
Spanning over 61 acres with 43.78 planted vineyard acres, the property offers substantial scale with the rare option to acquire an adjacent 155-acre parcel to significantly expand production.
The primary Cabernet Sauvignon vineyard is currently undergoing phased redevelopment, which will require additional capital investment and time before reaching full production capacity.
The multi-faceted nature of the property—combining luxury residential, commercial hospitality, and agricultural production—requires specialized management and carries higher overhead than a standard estate.
