My co-favorite of this year's crop of single-vineyard Cabernets is the 2019 Cabernet Sauvignon Chabot Vineyard, from a warm, obsidian-rich site on Glass Mountain. It boasts classic scents of crushed stone, pencil shavings and ripe cassis on the nose, followed by a full-bodied palate that's a paragon of balance, with rich, velvety tannins and a long, mouthwatering finish.
