Barbera (also known as Raspo, a Peduncolo, Amaro, Crna, Forte Mercantile, Nera, Nostrana, Riccia, Rissa, Rosa, Vera, Barberone, Barbexinis, Besgano, Cosses Barbusen, Gaietto, Lombardesca, Perricone, Pignatello and Ughetta) is a dark-skinned Italian wine grape variety that as of 2000 was the third most planted red grape variety in Italy. Barbera is believed to have originated in the hills of Monferrato in central Piedmont. It produces good yields and is known for its deep colour, low tannins and naturally high levels of acidity. Harvest usually takes place in late September – early October. The vines tend to thrive in less fertile, calcareous soils and clay loam.
