The white grape variety originates from France. Synonyms are Bordeleza Zuria, Chacolí Zuria, Cougnet, Courbeau, Courbi, Courbis Blanc, Courbu, Courbut, Courbut Blanc, Courtoisie, Hondarrabi Blanc, Hondarrabi Zerratia, Hondarrabi Zuri, Ondarabiya Zuriya, Ondaria Zuria, Ondarabbi Blanca, Ondarrabi Zuri, Ondarrubi Zurilla, Tocuri and Vieux Pacherenc. The name is derived from the shape of the vines (courbé = curved, bent).

The variety was first documented in 1783 in Jurançon. Its parentage is unknown. In France, it is often confused with the Arrufiac variety. In the Spanish Basque Country, it is known as Hondarrabi Zuri. There is no genetic relationship with the red variety Courbu Noir. There is also a white variety Petit Courbu (Xuri Zerratu); this is possibly a variety with smaller berries.
