The star of my visit to Diamond Creek was the 2019 Cabernet Sauvignon Volcanic Hill, which shows awesome purity and length. Vanilla accents blackberry, cassis and plum notes on the nose, while the full-bodied palate is rich and velvety, leading into a tremendously long finish, bursting with classic Cabernet fruit. It could use a few years in the cellar to gain nuance, and it should drink well for two decades or more after that.
