The 2016 Grande Reserva is mostly a 60/30 blend of Touriga Nacional and Tinta Roriz, with 10% Touriga Franca, aged for 14 months in new French oak. It comes in at 14% alcohol. Despite lower alcohol, in perception, this adds extra concentration compared to the regular Reserva, plus more power. The tannins are rather ripe, though. The easygoing Reserva is ready now, but the Grande Reserva might benefit from a year or two in the cellar. Still, this is not a great Grande Reserva this issue. Like the Reserva, it is a bit understated. Also like the Reserva, it is wonderfully fresh and easy to drink with food, a very elegant wine. I'm not sure this does enough to justify the big price spike over the regular Reserva, but it is a better crafted wine. They may separate more with age. In that regard, this should hold reasonably well. It doesn't have a big tannic backbone, but the freshness may help it age gracefully.
