Cakebread selects sauvignon blanc grapes from the best growing spots in Napa Valley, including their estate ranches in Carneros, Suscol Springs, Rutherford, and Calistoga. Cool nighttime harvest, whole-cluster press, and a variety of fermentation vessels-stainless steel tanks, neutral French oak barrels, and a concrete egg-enhance the complexity of this bright, crisp, mineral-driven wine.
