The Capolongo vine is an ancient authochthonal vine from Lazio, recently rediscovered, listed in the National Register of Grapevine Varieties in 2010, along with the vines Maturano b., Lecinaro n., Pampanaro b., Rosciola rs. These varieties have been recovered thanks to an Arsial project (Regional Agency for Agricultural Development and Innovation in Lazio) aimed at identifying the most qualified clones for vines already enrolled in the Regional register of grapevine varieties, to bring out the distinctive elements and allow the development in the territory.
So little is known of this variety and there are very few manufacturers that offer it.
Capolongo has a white, big, round berry with waxy, firm, deep yellow colored skin. The bunch is medium, compact, sometimes winged and the leaf is large, three-lobed or five-lobed.
