Photo of Dick Peterson, an eccentric and an inventor, and the Peterson dynasty, Heidi Barrett Peterson, his winemaker daughter and Holly Peterson, his chef daughter. Photo of Dick Peterson standing in his vineyard of Wrotham Pinot Noir in the foreground which is darker in color than his neighbor's Merlot in the background. Don't know if it really shows the difference in a photo.  Event on 7/14/05 in Napa. Craig Lee / The Chronicle Photo: Craig Lee
