Tours here take in spectacular gardens and underground tunnels cooled by a waterfall, and include the automated performance of a restored silent-movie-era pipe organ. On display near the tasting room is a 44-pound specimen of crystalline gold. The winery, known for Merlot, Cabernet Sauvignon, and Cabernet Franc, hosts concerts and other events. Its deli has picnic items. Ironstone is worth a visit even if you don't drink wine.
