Forged from vines grown in Coombsville's volcanic soils, this powerful, focused, penetrating Cabernet celebrates its origin in memorable detail. Two barrels made up the entire production in the 2021 vintage, each chosen for varietal focus, concentrated flavors, and a masterful combination of strength and elegance. You'll find these qualities in many of the world's most outstanding wines. At $95, Cabernet Sauvignon doesn't get any better!
