Wine: Santa Cruz's grape expert Prudy Foxx dishes on vines

It's the thick of harvest, and Santa Cruz Mountains viticulturist Prudy Foxx is making last-minute adjustments to her schedule. We were supposed to meet at Lester Family Vineyards in Corralitos, then head to another vineyard to check sugar levels in the grapes. Change of plans: It's Day 3 of a mid-September heat wave, and Foxx has determined that a client's chardonnay vineyard needs to be picked now.
