177 Ridge Drive Perched atop a private ridgeline, this extraordinary 67 +/- acre estate parcel presents a rare opportunity to create a legacy vineyard compound in one of Napa Valley's most coveted settings. Commanding breathtaking 180-degree panoramic views, the property captures the full sweep of the valley from the vineyards of St. Helena across the dramatic Mayacamas Mountains and, on clear days, extending to the San Francisco skyline. Ideally situated just above renowned neighboring wineries and contiguous to the prestigious Stags Leap AVA, the property offers both an exceptional residential setting and compelling vineyard potential. An approved Napa County erosion control permit allows for a 10 +/- acre hillside vineyard supported by rocky, well-drained soils -- an excellent foundation for producing premium wines, with additional potential plantable acreage. A generous, level building site provides an ideal canvas for a custom estate, with ample space for expansive lawns, curated gardens, and seamless indoor-outdoor living, while existing improvements enhance the immediate usability and lifestyle appeal of the property. A thoughtfully designed pool and cabana compound offer 1, 029 +/- sq ft of flexible living space, a full bath, a custom bar opening seamlessly to the outdoors, and a striking black-bottom pool and spa, creating a resort-like atmosphere suspended above the valley. The property is well-equipped for future development, with established infrastructure already in place, including electric service, an engineered septic system, high-speed internet, and exceptional water resources. A primary well, producing an estimated 200 gallons per minute at the time of drilling, is supported by a secondary backup well, a 12, 500-gallon concrete storage tank, and an on-site fire hydrant. Gated and private, the property offers a true sense of retreat, just minutes from Napa Valley's dining and culture, with convenient access to the San Francisco Bay Area. Combining scale, views, vineyard entitlement, and infrastructure, this property presents a rare opportunity to cultivate a curated vineyard estate in a setting of remarkable beauty and pedigree.
