Deep garnet-purple in color, the 2019 Chateau Buena Vista Cabernet Sauvignon Diamond Mountain District is a little closed to start, unfurling to reveal notes of baked blackberries, blackcurrant jelly, and baker's chocolate with hints of star anise, crushed rocks, and tapenade. The full-bodied palate has a firm, finely grained texture and plenty of freshness to support the taut, muscular black fruits, finishing long and minerally. Nice!
