At the center is a restored 1887 stone winery, now an extraordinary 5,424 sq. ft. gathering space with a grand fireplace, expansive glass doors, catering kitchen, and adjoining lawns. The 2,465 sq. ft. main residence, newly completed in 2024 and designed by Sasha Janev, offers 3 bedrooms, 3 baths, and seamless indoor-outdoor living. Additional structures include: 1,390 sq. ft. dwelling; 980 sq. ft. cottage; 438 sq. ft. lake house; 3,542 sq. ft. horse barn, and additional agricultural buildings. Also benefiting the ranch is a 105 acre-foot private lake used for swimming, fishing, and boating; 25.91 acres of vineyard planted in 2020 to Cabernet Sauvignon, Cabernet Franc, and Sauvignon Blanc; and approximately 47.4 of additional plantable acres. Two access points, wells, lake-fed irrigation and frost protection, underground utilities, generators, updated septic systems, roads, and trails support and enhance the property. Additionally, the property currently has standard homeowner's insurance making this a rare Napa Valley holding where land, water, history, and possibility come together.
