Sardinia’s wines have improved greatly during the last few years, thanks to a new generation of independent winemakers that has taken over the vineyards. The island is best known for its signature red, the potent, peppery Cannonau, the local name for the Grenache grape. Cannonau pairs well with grilled and roasted meat. Vermentino, a fresh, green-tinged white wine from Gallura (a region of northern Sardinia) is an ideal choice with seafood.
