The 2006 Costera Isola dei Nuraghi (100% Cannonau) is another knock-out effort from Argiolas. It reveals masses of super-ripe fruit bacon fat and licorice flavors. Today the fruit remains enshrouded in a wall of tannins so a year or two of further bottle age is called for, but this is a magnificent wine especially at this level. Cannonau is believed to be a descendant of Grenache and this wine will especially appeal to readers who enjoy the flavor profile of wines from the Southern Rhone. Anticipated maturity: 2009-2014.
