Francis Coppola Diamond Collection Black Label Claret, as its British-derived name implies, is a Cabernet Sauvignon-based wine created in the same style as classic Bordeaux. We use all five Bordeaux varietals in the blend—Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec, and Petit Verdot—and harvest grapes from Napa and Sonoma as well as the warmer El Dorado region.
