About This Home

Welcome to Stonehouse Cellars Winery & Bed & Barrel, an extraordinary 138-acre wine country estate in Clearlake Oaks, nestled within the scenic Long Valley AVA just north of Napa Valley. Rich in history and character, this family-owned property seamlessly blends a boutique winery, working vineyard, elegant guest accommodations, and expansive agricultural land, creating a truly rare opportunity to own a legacy estate in California wine country. The estate features approximately 13.5 acres of Cabernet Sauvignon vines, a 15,000-case annual production permit, and state-of-the-art winemaking facilities, offering exceptional potential for both established vintners and visionary entrepreneurs. The property is also situated within Agricultural Preserve zoning, which may provide valuable land-use advantages, preservation benefits, and favorable property tax opportunities associated with maintaining agricultural use, subject to buyer verification. Thoughtfully restored, the approximately 5,000-square-foot main residence and Bed & Breakfast deliver an unforgettable guest experience, combining timeless wine country charm with modern comfort. The property also includes a separate one-bedroom guest house, creating flexibility for guests, staff, or extended stays. In total, the estate features three structures, including the historic approximately 1,600-square-foot Stonehouse, which adds warmth, character, and versatility ideal for private accommodations, tastings, retreats, or special events. Natural beauty and sustainability are woven throughout the estate, featuring a spring-fed pond, reservoir, solar energy system, mature trees, rolling vineyard views, and open skies that create a peaceful and immersive wine country setting. With multiple potential income streams from wine production, hospitality, events, and agricultural operations, Stonehouse Cellars Winery & Bed & Barrel presents a rare opportunity to acquire a distinctive and versatile wine country estate with significant long-term potential. Square footage, acreage, vineyard plantings, production capacity, zoning, permitted uses, Agricultural Preserve benefits, water sources, infrastructure, structures, and all property details are approximate and based on seller and third-party information.
