he Vermentino variety can be found under fairly intensive cultivation in nearly all the Mediterranean coastal districts from Spain to Liguria and on the two major islands semi-enclosed by that arc, Corsica and Sardinia. It is also grown in small areas on the island of Madeira and at some places in southern France. Vermentino is clearly Spanish in origin. It seems to have traveled from Spain to Corsica in the 14th century and from there went on to Liguria. Its appearance on Sardinia was fairly recent, the final decades of the last century, and it was first planted in the Gallura at the island's northernmost tip.From the Gallura, the variety spread to the other leading viticultural zones of Sardinia, principally the provinces of Sassari and Cagliari. It was traditionally trained to the alberello Sardo system with three to four renewal spurs but new techniques of cultivation were recently introduced. Among them, the Guyot and Palmetta Speronata systems have yielded the best results.
Different from the Gallura, whose granitic soils are thin and poor, the other zones on Sardinia where Verentino is grown feature much richer and more fertile soils, which permit much higher yields of grapes. The result is a wine with a lower alcohol level that is smooth and quite drinkable, although with a much less assertive personality. However, the character is well delineated and differs from one area to the next.
