I also tasted the 2017 next to the 2016 Clos de Los Siete, and the difference was noticeable, as this 2016 was fresher and lighter. The varietal breakdown in this cooler year was 54% Malbec, 18% Merlot, 12% Cabernet Sauvignon, 12% Syrah, 3% Petit Verdot and 1% Cabernet Franc, slightly higher in Malbec than in 2017. The wine is approachable, balanced and nicely crafted, produced in a nice-to-drink style with fine-grained, chalky tannins. I think there's a little more nuance and elegance here.

Dark ruby-red. Alluring scents of blackberry, cassis, licorice, bitter chocolate and espresso. Suave, fine-grained and flavorful, with its sweet/savory dark fruit and spice flavors complemented by a chocolate note and nicely framed by harmonious acidity. Finishes with dusty tannins and noteworthy echoing length. This is a very good, fresh vintage for this bottling, which is an excellent value year in and year out.
