The vines grow in thousands of tiny rectangular plots called currais, walled in by hand-stacked black volcanic rock — a UNESCO-listed landscape so labor-intensive that some plots hold only a handful of vines, and Russia's Tsar Nicholas II was reportedly a devoted fan of the wine it produced.
Vinho do Pico is a mineral, saline white wine made mostly from Verdelho grapes grown directly in volcanic soil on Pico Island, protected from Atlantic winds by low basalt walls. It's crisp and distinctly briny, tasting of the ocean that surrounds it.
