Priorat, Priorat, Priorat! High alcohol, high acid Grenache, almost always with soft yet generous tannins. Powerful, yet almost always lifted and super pretty. Great for Napa Cab drinkers that want to try something new but not totally unfamiliar. Look for wines by Alvaro Palacios, Sara Perez, Rene Barbier, or Ester Nin. All big names that should be available in most major markets and all make great wines up and down the price scale. Plenty of great lesser known estates too but I'm not sure what is available in your market.
huge yes on the priorat call
