John Caldwell, founder and owner of Caldwell Vineyards in the Coombsville district of Napa Valley, was one of the first vintners to realize Coombsville’s potential for fine wine. He was at the forefront working with the French regulatory agency ENTAV (Établissement National Technique pour ‘Amélioration de la Viticulture) to import French clones into America. He is the author of “Wine Grape Clones for Professionals.”
