I tasted two consecutive vintages of the single-vineyard Malbec from Alto Agrelo, the first of which was the 2014 Malbec Serenade, from a challenging, cool and wet year, the second of a series of rainy vintages. The vines were planted in 1935 at 1,050 meters altitude with a massal selection. The range has the same vinification and élevage to show the differences in terroir, fermentation in concrete and aging in French oak barrels (66% of them new) for 12 months. I see a huge vintage effect here, this is earthy and the fruit feels a bit cooked, and there are some hints of leather. The wine comes through as a bit heavy, ripe. There was close to 15% alcohol but a high 7.31 grams of acidity. I'd have difficulties drinking more than a glass of this, and I much preferred the 2015. And some people say there is no vintage effect in Argentina... 4,206 bottles were filled in March 2016.
