The 2015 Xisto, an old-vines field blend released only in certain years, is Touriga Nacional, Touriga Franca and Tinta Roriz, all aged for 20 months in French oak. It comes in at 14.5% alcohol. Far too marked by wood just now, this also shows off all of its great potential. Sensual in texture, this concentrated Xisto easily coats the palate and fills the mouth. It shows finesse and balance as well. What it needs at this point is to pull in the wood and acquire complexity. That will only happen with time. While it is balanced enough to drink well right now—it's pretty good!—it needs a couple of years in the cellar to show everything it has. Given the price, you don't want to waste it. Come back around 2023, roughly, for results that might be closer to peak.
