Cannonau is the Sardinian name for Grenache, and on this Mediterranean island it tends to give warm, sun-ripened reds with bright red fruit and a touch of herbal scrub. This bottling from Argiolas, the Costera, draws on that tradition: a still red from the Cannonau di Sardegna DOC, made entirely from the grape, in a vintage (2021) meant to show the variety's generous, open character.
