The 2018 Cabernet Sauvignon Howell Mountain is a typically long-term proposition, coated in dusty tannins and cedary oak. It will take time for the cassis, blueberry and slightly pine-scented backbone of this wine to emerge, as for the moment it's almost difficult to taste. Yes, the concentration is present, the tannins are almost silky-ripe, but the structure of this medium to full-bodied wine is unassailable. Hands off for at least five years, and probably more, to judge by how past vintages have evolved.
