The story

  • Basement

Perched majestically above the shimmering expanse of Lake Sonoma, Rockpile Ranch presents an exclusive 755-acre legacy estate within Northern California's highly sought after Rockpile AVA. This extraordinary mountain sanctuary seamlessly marries a pristine natural wilderness with a world-class, income-producing viticultural enterprise, featuring 58 meticulously farmed acres of vines with an additional 8 acres plantable across 11 premium varietals. Situated entirely above the marine fog line at elevations surpassing 800 feet, the terroir benefits from intense high-altitude sunshine and cooling Pacific breezes, yielding exceptional, highly sought-after mountain fruit. At the heart of the compound rests a beautifully restored 2,600 SqFt 1920s craftsman farmhouse, offering four bedrooms, three bathrooms, a modern kitchen, and expansive covered porches that frame sweeping, panoramic ridgeline vistas. Complementing the primary residence is a versatile 2,200 SqFt the 1901 built Throop House, ideal for hosting distinguished guests or housing an estate manager, alongside a heritage 3400 SqFt redwood barn with both a Caretaker's unit and a Cowboy Bunk House, a two-vehicle carport, and a 1,120 Sq Ft workshop. Engineered for ultimate autonomy, the property operates completely off-grid with a solar array, battery storage, and diesel generator, all supported by an abundant network of wells and natural springs. Encompassing miles of private trails, dramatic oak-studded topography, and premier sporting opportunities for blacktail deer and quail, Rockpile Ranch stands as a rare, turnkey masterpiece designed for the ultimate wine country escape.
