One of the most common misconceptions, at least amongst American wine drinkers, is that a single varietal (or even a single vineyard) wine is always the best. This completely omits the complexity. depth and synergies that a blend offers. As in, the structure of Cabernet Sauvignon, the supple smoothness of Merlot, etc. Why not take advantage of both? Here are three blends that are more than just a sum of their parts:

Trefethen 2007 Red Wine Napa Valley Double T ($25).
