Tucked into a rock face in the Mayacamas range, Storybook occupies a picture-perfect site with rows of vines rising steeply in dramatic tiers. Zinfandel is king here, and there's even a Zin Gris, an unusual dry Rosé of Zinfandel grapes. (In Burgundy, Vin Gris—a pale Rosé—is made from Pinot Noir grapes.) Tastings are preceded by a low-key tour that includes a short walk up the hillside and a visit to the atmospheric tunnels, parts of which have the same rough-hewn
look as they did when Chinese laborers painstakingly dug them around 1888.
