In contrast to the more open and seamless Insignia, the 2018 Cabernet Sauvignon Backus Vineyard is a beast of a wine based on 91% Cabernet Sauvignon, 5% Petit Verdot, and 4% Malbec that saw the same two years in new barrels. More blackcurrants, black cherries, mulberries, graphite, crushed stone, lead pencil, and tobacco notes define the nose, and it's full-bodied, with an incredible depth of fruit and richness on the mid-palate, building tannins, and a great finish. With air, it picks up this intriguing, burning ember, iron, almost Hermitage-like character, yet it shuts down with extended air and becomes more tannic and unyielding. It's a brilliant wine, but the cellar is going to be your friend. It should hit full maturity in about a decade and will evolve for 30-40 years.

The 2018 Cabernet Sauvignon Backus Vineyard is a blend of 91% Cabernet Sauvignon, 5% Petit Verdot and 4% Malbec, aged for 24 months in 100% new French oak. Deep purple-black colored, it soars out of the glass with notes of plum preserves, baked black cherries and crème de cassis, plus nuances of pencil shavings, bouquet garni, crushed rocks and unsmoked cigars with a touch of cardamom. The palate is full-bodied and seductively rich, delivering mouth-coating black and blue fruit preserves with loads of exotic spice accents and a velvety texture, finishing long with a refreshing herbal lift.

The 2018 Cabernet Sauvignon Backus Vineyard is a very pretty wine, but it also comes across as a bit compact. There is plenty of energy and drive if not quite the volume that is such a signature of this Oakville Cabernet. Time in the glass brings out layers of dark red/purplish fruit, rose petal, lavender and mint. The 2018 is a gorgeous wine in the making. Readers should expect a mid-weight, relatively restrained vintage of this flagship Phelps Cabernet.

This sports the typical Oakville profile of dense plum, black currant and blackberry fruit flavors, but the fruit is more restrained than most, with licorice root, warm earth, menthol and roasted alder notes playing an equal part. Everything melds steadily through the long, smoldering finish. Built for the cellar. Best from 2023 through 2040.
