The First Ladies of Sonoma's wine industry know all about growing patterns, sugar brix and fermentation processes. But once a year, they prove that they also know how to shimmy and chassé for charity when they collectively become Magnum Force during the Harvest Wine Auction. Women such as Ramona Nicholson of Nicholson Ranch Winery, Eva Bertran of Gloria Ferrer Winery and Betsy Spann of Spann Vineyards are just a few of the dancers who spend months practicing with lead choreographer Suzy Fridell, co-owner of Glen Lyon Winery. Fridell is a decorated performer who has danced her way across stages from Broadway to Paris and back.
