It’s something of a paradox. How can a region as hot as Portugal’s Douro Valley, home of full-throttle Ports, also produce elegant, graceful white wines? The answer lies in site selection, picking dates and the acidity of the local grapes. This cuvée of Rabigato, Gouveio, Viosinho and Arinto is a delicious example from winemaker Rodrigo Martins. It’s both lightly tropical and refreshing, with notes of caramelised pineapple, pear and green apple, fresh, almost salty acidity and a hint of kerosene that’s reminiscent of an aged Riesling. Remarkable at the price.
