The 2011 Vintage Port "Nacional" is a field blend aged for 18 months in wood before release. It comes in with 94.6 grams per liter of residual sugar and, if anything, tastes drier. This is a monumental Nacional that justifies its cult reputation. Still showing rather primary, young fruit, it is laced with herbs and a hint of resin. It is just plain delicious, even while showing some austerity. Fresh, clean and lively, its tension on the finish serves it in good stead, enlivening the wine along the way. The balance is perfect. Elegant but still very concentrated, more than the 2004 also reviewed, it expands in the glass as it airs out, coats the palate nicely and then becomes ever more intense. If the first tastes were all about the fruit, this wound up being about its backbone and firmness, what I typically expect. The tannins are not searing, in a sense--they are hard, not harsh--but make no mistake: it shuts down with a bang and does a fine job of seizing the tongue. It's built for the long haul, of course.
