Semidano is a native Sardinian white grape variety. The grape has ancient origins, and though it was once quite common, it became a rarity after phylloxera destroyed most of its plantings. It was mostly replaced by more resistant and productive Nuragus.
Semidano is now mostly planted around Oristano. The grape is a part of Sardegna Semidano DOC—which includes dry, sparkling, and sweet passito styles—with a subzone Mogoro, which is considered the best for this white grape. Semidano produces straw-colored white wines with a fresh character and good acidity.
