One of the first, if not the first, of the proprietarily named Napa Bordeaux blends, Phelps Insignia has been one of California's greatest Cabs for decades. This is their 30th anniversary bottling, and it's worthy of the tradition. Ultrarich and smooth, with a mouthfeel that's pure velvet, it's fairly thick in tannins now, suggesting cellaring. But it's huge in blackberry, dark unsweetened chocolate and spicy plum fruit, and will easily hold for a very long time. Best now, if carefully decanted, and through 2020.
