Another protected regional extra virgin olive oil is Canino, produced in the province of Viterbo and registered since 1996. It is produced in the lands once feuds of the Torlonia family, an area located to olive growing since Etrurian times including the municipalities of Canino, Arlena, Cellere, Farnese, Ischia di Castro, Tessennano, and part of Tuscania and Montalto di Castro; the total cultivated surface is about 30,000 hectares.
The main varieties are Canino, a local olive variety, Leccino, Pendolino, Maurino, and Frantoio, either in purity or blended. The acidity, ranging from 0.15% to 0.5%, is one of the lowest among Italian extra virgin olive oils. The oil has a green colour with golden hues, a fruity odour, and a pronounced flavour, slightly pungent when young and with a bitter aftertaste.
