Inglenook Winery, founded in 1880 by Finnish sea captain Gustave Niebaum, features a substantial stone chateau and gravity-flow winery designed beginning in 1881 by San Francisco architect William Mooser in collaboration with Hamden McIntyre. The massive, three-story structure is 220-feet long and 72-feet wide at its center, topped by a tin roof, dormered windows, and a cupola. The walls are several feet thick and made of sandstone quarried on the estate with trim stone from nearby St. Helena. The vaults are skewed arches stressed by cables from the original San Francisco cable car line. In 1975, Francis Ford and Eleanor Coppola acquired the property, later reuniting the original vineyards and restoring the historic winery to its former stature. In 2022, Niebaum-Coppola Estate Winery completed a 22,000-square-foot underground production cave, integrating advanced technology with the estate’s 19th-century architectural legacy.
