Castello di Amorosa is an authentically styled 14th-century Tuscan castle winery in Calistoga, Napa Valley, built stone by stone using historically inspired medieval construction methods. Founder Dario Sattui's lifelong passion for medieval architecture ensured every detail reflects authentic European tradition, from hand-laid stonework to period design elements. The estate produces exclusively available award-winning wines while offering wine tastings, tours, and educational events in a genuinely atmospheric setting. Visitors can explore the extensive castle grounds, enjoy Italian-style wine tours, and access on-site lodging options, all while surrounded by vineyards and the architecture of a European dream transplanted to California wine country.
