Sunshine Mountain Vineyard is guided by a winemaker with 30 years of experience who oversees the complete vine-to-bottle process at this unique San Marcos estate. The winery's most distinctive feature is its three earthen caves carved into the property's hillside where wines are aged in oak barrels — one of the very few wineries in San Diego County to offer cave aging. The rustic mountain charm and panoramic views make it a beloved destination for wine lovers seeking something beyond the typical tasting room experience.
