Welcome to Spiriterra Vineyards! We are a small, family-owned vineyard located near Howell Mountain in the hills east of St. Helena - a premium winegrowing region. We are proud to bridge two historical winemaking traditions. We offer a limited-production Cabernet Sauvignon wine, the grape upon which Napa Valley's reputation was built. We are also excited to introduce Napa Valley's first dry Muscadine and sweet Scuppernong wines. Muscadine and Scuppernong are native to the southeastern United States, with a respected winemaking history dating back to the 1500s, but are thriving here in the Napa Valley.
