The white grape variety comes from Sardinia (Italy). Synonyms are Bariadorgia Bianca, Bariadorza, Barria Dorgia, Gregu Bianco, Carcaghjolu Biancu, Carcajola, Carcajola Bianco, Carcajolo Blanc, Gregu Bianco. Bariadorgia comes from the Sardinian area of Alghero. It is identical to the Corsican Carcajolo Blanc, which was first mentioned here in 1822. According to DNA analyses carried out in 2007, Gregu Bianco, which is found in the Sardinian region of Campidano di Terralba, is also identical. However, in spite of apparent synonyms or morphological similarities, it should not be confused with the rather similar Corsican variety Biancu Gentile. The Corsican red variety Carcajolo Noir is also not related. This medium-ripening vine is very productive, which is also indicated by its name (Carcajolo means "heavily loaded"). It is susceptible to botrytis and powdery mildew. The variety yields acidic, aromatic white wines with moderate alcohol content. In Corsica it is/was cultivated under the name Carcajolo Blanc mainly in the southern areas of Sartène and Figari. However, no stocks were recorded in 2016 (statistics Kym Anderson).

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
