Sketch of Vince Tofanelli’s vineyard located in Calistoga (Napa County) just before harvest. Though Vince sells most of his grapes to wineries, he reserves a portion for his own label, Tofanelli Wines. They are some of the best I’ve tasted. Vince was nice enough to allow me access to his vineyards many times over the course of a year. I cover all the details in my book, “Impressions of Wine County.”
