The 2000 Cain Concept Library Edition is a real treat. The Cain Concept is based on the classic blenchland Cabernet Sauvignon that made Napa Valley famous. The Concept is a blend on Cabernet Franc, Petit Verdot, and Merlot. This combination of flavors develop into a complex bouquet and a refined, rich and balanced finish. The Library Edition was bottled without filtration.
