Heralded as a near-flawless vintage in Napa Valley, 2010 had the latest onset to harvest in several decades. We crushed the first grapes after Labor Day, about two weeks later than average. The late onset to harvest resulted from above-average rainfall and cool temperatures that persisted into May, followed by a mostly cool, foggy summer that slowed fruit maturity. But just as we started worrying that the grapes would never ripen, Mother Nature surprised us with heat spells to boost their flavors and sugar levels. The long hangtime and full maturity added up to exceptionally rich wines with exquisite balance.
