Sardinia is home to Vermentino (the Rolle of southern France), one of the white wines that Italians love the most: always crisp, lemony, and herbal. Vermentino is the ideal Sardinia wine soul mate for the many seaside fish preparations typical of the island. The best Vermentinos are labeled ""di Gallura,"" as opposed to the more generic ""di Sardegna."" Sardinia's diversity of microclimates and soils, plus the astonishing mix of native grape varieties still found on the island, help explain the great range of red wines available here, with Grenache (called Cannonau in Sardinia) and Carignane being the most dependable.
