Grape residues from the nuragic age argue that Sardinians were making wine long before classical times, giving the island one of the Mediterranean's oldest claims to a native wine culture. Centuries under the Crown of Aragon and Spain left the modern vineyard its backbone: cannonau, the local grenache, and carignano, still grown ungrafted in the sands of Sulcis.
Each corner of the island has its speciality — Gallura's granite hills give a saline vermentino, the island's only DOCG, while the south holds to its deep, sun-cured reds. Sardinia's most curious fame is demographic: the "blue zone" villages of the interior, where cannonau is drunk daily, count so many centenarians that researchers keep returning to ask why.
