94 from the Wine Review Online and 93 from Wine & Spirits:
Duckhorn's estate at the higher elevations of Red Mountain, planted in 2013, is becoming a precocious fruit source. This 2017 offers a lot of wine for the price, with intriguing tension between its savory elements—tobacco leaf, sun-dried tomato skin, cedar frond, mocha—and firm dark-plum fruit. It’s a weighty wine, with formidable tannins, but it's delivered wholly on the rails, detailed and on point for steak.
Also “Outstanding” ratings from Vinous, The Wine Advocate, the Wine Enthusiast and Dunnuck, who says:
The 2017 Cabernet Sauvignon Red Mountain (84% Cabernet Sauvignon, 11% Merlot, 2% Mourvedre, 2% Petit Verdot, and 1% Syrah) sports a deep purple color to go with lots of smoked black fruits, chocolate, and classic Red Mountain minerality. Medium to full-bodied, nicely concentrated, and balanced, with ripe tannins, it's another impressive wine from this team that will evolve for 10-12 years, if not longer.
