Malvasia di Bosa DOC

The other great oxidative wine of Sardinia, made in the Planargia hills behind Bosa on the western coast. It is rarer than Vernaccia di Oristano, made by a handful of families, and by some distance one of the finest and least-known wines in Italy.

The Terroir The registered file describes a hill zone of central-western Sardinia on substrates that are predominantly calcareous and sandstone, sometimes marly. The climate is Mediterranean with mild, moderately rainy winters and hot dry summers in which temperatures exceed 30°C; constant sunshine, temperature swings and solar radiation allow regular ripening and, in the file’s phrase, the exaltation of the aromas in the wine. Training is guyot and alberello. Everything — vinification, ageing, bottling and bottle-refinement — must happen inside the zone.

Under the Veil The traditional method is the same as Oristano’s: the wine is fermented dry and left in part-filled casks where a film of yeast forms on the surface and works on it for years, unfortified. The result is amber, nutty and bone-dry, with the sharp saline lift that only flor produces. The modern disciplinare is broader than the tradition — the file registers still, sparkling, quality-sparkling and dried-grape categories, and describes wines running from dry to sweet, straw to deep gold, with an aromatic, fruity, intense, complex, fine and delicate nose. The bottle to look for is the old, dry, flor-aged one.

Grape Varieties Malvasia di Sardegna alone. It is a genuinely aromatic Malvasia, unrelated to the neutral Malvasia di Candia of central Italy, and it is what separates this wine from its Oristano cousin — where Vernaccia di Oristano gives almond and salt, Malvasia adds apricot, orange peel and a floral top note that survives even years under the veil.

The Critical Take Bosa and Oristano are the two halves of an argument nobody in Italy is having. Both are unfortified, flor-aged, and made from a single local grape; both collapsed commercially when the world stopped drinking oxidative wine; both are now down to a few producers and a few hundred hectares between them. Bosa is the more perfumed and, at its best, the more complete — there is a case for calling it Sardinia’s greatest wine. It costs less than a mediocre Barolo.

Planargia The zone is a basalt and limestone plateau falling to the Temo river and the sea, and Bosa itself sits below a Malaspina castle on the only navigable river in Sardinia. The vineyards are inland and above, on ground too poor and too steep for anything else.

At the Table The dry version with bottarga, almonds, aged pecorino sardo and salted fish; the sweet with seadas and hard biscuits. Serve at 12–14°C in a small glass. An open bottle will hold for weeks.
