Cannonau di Sardegna DOC is one of Sardinia's most distinctive appellations, and it actually covers the entire island. The best vineyards, however, lie in the hills north and east of the Gennargentu mountains, from Nuoro out to Capo Ferrato on the southeastern coast. Here you will also find the appellation's three official subzones: Oliena south of Nuoro, Jerzu a little further south, and Capo Ferrato out by the coast.
The grape Cannonau is Sardinia's local name for Grenache, known as garnacha in Spain and grenache in France. It was reportedly brought to the island by Spanish conquerors in the thirteenth century, and it has since settled in well to the extreme Mediterranean heat and drought in which it thrives.
In terms of style, Cannonau di Sardegna is more versatile than many think. You will encounter dry red wine, but also semi-sweet and sweet red, rosato and liquoroso. That offers a wide selection to explore if you want to get to know the grape from several sides.
The flavour profile is earthy and rustic with notes of tar, tobacco and wild red berries. The wines are typically medium-bodied, and they have an aromatic ripeness that often makes them seem more developed than their age suggests. A particular hallmark is the colour: Cannonau develops a brownish tinge even at a young age, so where you might expect deep ruby red, you instead encounter lighter, more garnet or brick-red shades despite the concentrated flavour.
The quality can vary from producer to producer, and that is part of the charm of exploring an appellation that spans an entire island with widely differing terroir. The rustic, spicy character suits hearty food, and a bottle of Cannonau is an obvious starting point if you want to experience the warm, sun-driven expression of Sardinia.
