Cardinale is one of the oldest Oakville wineries in Napa Valley. Cardinale only makes one wine each year. The wine consists mainly of Cabernet Sauvignon with a smaller part of Merlot. The winery has vineyards throughout the Napa Valley, including Diamond Mountain, Spring Mountain, Howell Mountain, and Mount Veeder. A blend is made from all individual plots every year, so a different unique Cardinale every year.
