Trevi Hills Winery in Lakeside grows estate Syrah, Sangiovese, Zinfandel, and Sauvignon Blanc on a 4-acre Muth Valley Road vineyard planted in 2013, making it the closest working winery to downtown San Diego. The vineyard's small-lot vintages ferment inside a 3,000-square-foot production facility, an artisan-scale operation on the Wildcat Canyon corridor that parallels the handmade batch work at Old Fashioned Creamery at Barona at the nearby resort complex. The tasting room and patio overlook the 800-acre Trevi Hills residential community, offering panoramic sightlines west toward the Pacific Ocean and the downtown San Diego skyline. A Certified Sommelier credentialed through the French Court of Sommeliers directs winery operations, guiding production decisions on harvest timing, barrel selection, and blending ratios for the estate's red-blend program. The vineyard occupies land historically inhabited by the Kumeyaay, whose cultural legacy is documented at the Barona Cultural Center & Museum five miles north on Barona Road. The amphitheater seating, shaded gazebos, and sunset-facing patio host private events from 50-person receptions to full-scale weddings, with estate wine service and on-site catering infrastructure built into the 3,000-square-foot facility.
