(Reuters) - There must be something in the air. Maybe it's the fog? Maybe it's the soil? But there has to be something that has led so many women to make wine in Sonoma, California.There is, of course, Helen Turley. America's answer to France's flying winemaker Michel Rolland. This grande dame of California cult wines has her latest venture, Marcassin Vineyards, 10 acres or so producing Pinot Noirs and Chardonnays on the Sonoma Coast. In the 1980s, it was Judy Jordan who founded J Vineyards. Given her proclivities for sparkling wine, naturally enough she planted Chardonnay, and eventually Pinot Noir and Pinot Gris.
