95 points Luis Gutiérrez (Wine Advocate): "[$160 list] The 2015 Adrianna Vineyard River Stones is from the stonier part of Adrianna Vineyard in Gualtallary, from vines right next to the river bed at 1,349 meters in altitude, a part that tends to produce more austere wines. There is higher ripeness compared with 2014 and 2016. Even though it might show a little more exuberant in comparison, the palate reveals an austere wine that has a large personality but is superbly balanced, with very fine-grained tannins and very good balance. But sometimes comparisons can be tedious, and there are wines that suffer. This is one of them, but it is still superb. 4,800 bottles produced. It was bottled in July 2017. Drink: 2018-2025. (Jun 2018)"
95 points Tim Atkin, MW: "The soils of the River Stones Malbec, located in a dry creek, are identical to those of the White Stones Chardonnay, producing a rich, spicy, textured wine that’s fermented with 100% stems. Plum and bramble fruit flavours are complemented by understated oak and a ripe, figgy finish. 2019-26. (2018)"
94 points Stephen Tanzer (Vinous): "($160 list; 14.6% alcohol; from vines on stony soil over calcaire; vinified with 40% whole clusters; winemaker Vigil begins with a bit of carbonic maceration, then does a traditional fermentation, using only punchdowns): Bright, dark ruby. Strong crushed-rock minerality on the nose, along with aromas of blackberry, cassis, licorice and bitter chocolate, all lifted by a piquant floral quality. Densely packed but precise and perfumed owing to its chalky energy, conveying an impression of moderate ripeness to its dark berry and light herb flavors. Quite tight and youthfully imploded but already displays an alluring subtle sweetness. Perhaps most impressive today on the back end, which features substantial firm but fine-grained tannins and terrific rising, expanding length. Drink: 2022-2029. (Jul 2018)"
