Barbara Banke of Jackson Family Wines does nothing that isn't infused deeply with passion. So when I heard that she entered a partnership with a long-standing friend, Peggy Furth - formerly of Chalk Hill Estates - to develop a line of wines called Windracer, I was immediately curious. These are two class-act, business-savvy women, who earned their stripes and their very considerable paychecks on their own, well before they became part of California's North Coast elite vintners. I knew that the wines and terroir they chose would be distinctive.
