A similar blend each year, the 2015 Unus is 65% Malbec, 25% Cabernet Sauvignon and 10% Petit Verdot that matured in French barrique for 16 months. It's a blend that Roberto de la Mota likes, and it mixes grapes from both Luján and Valle de Uco. But in this year, he used quite a lot of grapes from Luján de Cuyo. The Petit Verdot comes from a massal selection. There is less new oak this year, as most of the Malbec was in used barrels, and it feels nicely integrated. It's a very serious, balanced and somewhat austere wine, combining power and elegance, perhaps with less concentration than in some past vintages. It's very tasty, and the tannins are very refined, where you see the hand of a very good winemaker at work. It's approachable now, but it should have a long life in bottle—it has fresh fruit and nice balance and acidity to do so. The Bordeaux accent is more noticeable after some time in the glass.
