Coombsville, just east of the town of Napa, is a new AVA bounded by the walls of an ancient volcano. It’s a relatively cool spot in Napa Valley, close to the San Pablo Bay, with volcanic soils suited to cabernet. Dan and Deedee Sodaro planted 9.5 acres of Bordeaux varieties there, dug a cave and hired Dawnine and Bill Dyer to design their winery and produce their wines. In 2013, they enlisted Denis Malbec, the consultant and former cellar master of Château Latour, to assemble their current team. Their 2010 Felicity blend has the elegant feel of a great cabernet. Between the team and the cool site, this is a cabernet producer to follow.
