Napa Valley's 2010 vintage will be remembered as having a notably cool growing season, with the latest onset to harvest in several decades. "Summer's cold nights, dipping to the 40s and 50s, really set the grapes' deep colors, flavors and balance," Tom explains. The growing season got off to a late start when cold, wet soils in March and April delayed budbreak. The above-average rainfall and cool temperatures persisted into May, followed by a mostly cool, foggy summer that slowed fruity maturity. But just as we started worrying that the grapes would never ripen, Mother Nature surprised us with heat spells to boost the grapes' flavors and sugar levels. Tom reports that the grapes' quality was "as good as it gets."
