Plumpjack Estate Cabernet Sauvignon. Every year we drink just one and buy just one to replace it when we're in Napa.
We drink our lone bottle of 2004 Cabernet Sauvignon a couple weeks ago over a nice dinner at Candelas in Coronado. It's an impossibly smooth and jammy Cab that somehow finishes with big tannins that are perfect to wash down a juicy steak. We didn't want this bottle to end, but like all bottles it did. Alas, there's always next year.
