What to Expect
Expect a full-bodied dessert wine with rich, dark fruit flavors that will complement any sweet dessert or pair beautifully with chocolate-based dishes. As a Cabernet Sauvignon variety, this wine offers firm tannins and a robust character typical of its grape origin in California, making it perfect for cooking applications as well.
