One of the older vintages they are selling as a library release is the 2013 Merenzao, a wine that is now called Risco Mernzao. To me, this is one of the benchmark bottlings for the grape—called Merenzao and Bastardo in Spain and Portugal, though it is the same as Trousseau—in Spain, together with the bottling from Quinta da Muradella. This was produced in a more earthy and rustic style, closer to the wines from Lucien Aviet in Jura than the Bastarda from Fedellos do Couto in Ribeira Sacra. Since I tasted it some four years ago, it has developed more tertiary aromas, turning earthier and more reminiscent of an aged Trousseau, with notes of forest floor, smoked paprika and rusty nails. The palate has fine-grained tannins and is nicely textured, talking about the stony soils more than the grape. It's tasty and long—it has aged well. This is now ready for prime-time drinking.
