Composed of 62% Cabernet Sauvignon, 19% Cabernet Franc, 15% Merlot and 4% Petit Verdot, the 2015 IX Proprietary Red Estate sports a deep garnet-purple color and nose of smoked meat, blackberries and black currants with suggestions of baking spices, dark chocolate, fertile earth, dried Provence herbs, cardamom and lavender plus a touch of cigar box. Full-bodied, rich, firm and restrained, it has a lovely earthy, soft-spoken style at this youthful stage, promising great things to come over the forthcoming 25-30 years.Robert Parker Wine Advocate | 100 RPLastly, the 2015 IX Estate is reminiscent of a hypothetical blend of the 2013 and 2014, with a ripe, sexy, exuberant style carrying loads of blue and black fruits as well as notes of tobacco, iron, truffly earth, and lead pencil. A blend of 62% Cabernet Sauvignon, 19% Cabernet Franc, 15% Merlot, and the rest Petit Verdot, it’s full-bodied and has loads of up-front fruit, ripe tannins, and a gorgeous finish. As with the 2012 and 2014, it has this incredible lift and elegance and already offers pleasure. Nevertheless, I’d give bottles another 3-4 years if possible, and this will evolve for 30-35 years in cold cellars.Jeb Dunnuck | 100 JDThe IX Estate is the most brooding and tannic of these 2015s from Colgin. Huge swaths of tannin enshroud the fruit in this decidedly virile, intense Pritchard Hill red. Readers will have to be patient, as the 2015 is going to need at least a few years to come into its own. Even today, though, it is a stellar wine.Vinous Media | 97 VMThis is a broad-shouldered wine, underscoring the richness of the vintage. But it is also bright and fresh with a light bitter and hazelnut character on the finish. Full-bodied, focused and textured with a dusty tannin mouthfeel. Tangy and long at the finish. Enticingly fruity. Drink in 2021.James Suckling | 97 JSAssertive, with an agreeable texture that eases the tannic strength, making this a powerful expression of extracted Cabernet flavors like dark berry, cedar, graphite, tar and more. Cabernet Sauvignon, Cabernet Franc, Merlot and Petit Verdot. Best from 2021 through 2034. 1,050 cases made.Wine Spectator | 94 WS
