Trefethen has been on a roll the last few years, producing some of Napa's most spectacular Cabernets. This bottling, which contains minor quantities of Petit Verdot and Merlot, spent 28 months in new French oak barrels. The fruit is incredibly ripe and intense, with flavors of black currants and chocolate-covered cherries. As hard as the tannins are, they must have been even more aggressive two or three years ago, so kudos to Trefethen for holding the bottle back for five years. This beauty is just now beginning its long journey. Drink now–2020.
