Gandona Wine Estate is located on prestigious Pritchard Hill and represents a rare opportunity to steward one of Napa Valley's most significant mountain vineyard estates. Sited up the very private middle driveway of Pritchard Hill Gandona enjoys glorious, elevated views over Lake Hennessey. The over 100+ acre estate boasts +/- 18 acres of Cabernet Sauvignon and Cabernet Franc, offering scale, credibility, quality and scarcity that define the very best of Napa Valley. Existing entitlements and turn-key improvements consist of a 20,000-gallon production permit, anchored by a +/- 3,500-square-foot winery and tasting room, together with a newly expanded +/- 8,000-square-foot cave, crush pad, and infrastructure thoughtfully designed to support future expansion. The Estate provides an established ultra-luxury platform for continued production and long-term growth from one of Napa Valley's most coveted terroirs. The +/- 5,000-square-foot main residence captivate the lake views beautifully. Construction materials include large stones sourced from on site vineyard and cave development, large scale steel sturctural elements, concrete, limestone and imported Portuguese tile. Four luxurious en-suite bedrooms provide comfort and privacy. The guest house and cottage are located in the vines provide separation and privacy yet offer the same lake views. Throughout the Estate, majestic oak trees, dramatic natural boulders, and sweeping views create a setting that is both striking and unmistakably Pritchard Hill/Napa Valley. An opportunity of this prestige, scale, and infrastructure rarely becomes available. Gandona, at this moment provides a rare opportunity to join Napa Valley's enduring legacy of world-class wine producers.
