A rare and distinguished offering in the heart of Temecula's prestigious De Portola Wine Trail. This extraordinary 10.38-acre parcel is not merely a residence; it is a fully realized opportunity for a private luxury estate or an emerging artisanal winery. The Vineyard Foundation: The acreage currently hosts meticulously maintained varieties of Cabernet Sauvignon, Cabernet Franc, and Zinfandel, providing an immediate, high-quality foundation for a boutique label. With desirable Winery District zoning, the property is poised for the development of a Class II winery, providing an ambitious owner with the permits to craft, bottle, and market their own Temecula Valley vintage. The Residential Retreat: The charming two-story residence serves as an elegant owner's retreat or a sophisticated tasting room prototype. Featuring dual-facing balconies, the home is perfectly sited to capture panoramic 360-degree views—from the morning spectacle of hot air balloons to the majestic Palomar Mountain at sunset. The dedicated winemaking room and four-car garage offer the practical infrastructure for both private and commercial operations. The Visionary Potential: Beyond the existing structures, a generously sized pad presents a unique architectural canvas for expansion—be it an elevated custom villa, a world-class hospitality venue, or a serene pool oasis. Situated directly across from acclaimed Leoness Cellars, this is an unparalleled chance to secure a legacy-grade holding in one of Southern California's most dynamic viticultural regions. This is the definition of wine country provenance.
