The red grape variety comes from France. Synonyms are Bordelais Noir, Madiran, Madiron, Mouston, Moustron, Moustrou, Moustroun, Tanat, Tannat Gris, Tannat Noir, Tannat Noir Male(France); Bordelez Beltza(Spain); Harriague(Uruguay). It was first mentioned in 1783 under the name Tanat in what is probably the exact area of origin, the Hautes-Pyrénées department. According to DNA analyses carried out in 2009, there may be a parent-offspring relationship with the Manseng Noir variety, and relationships with the Baroque, Courbu Blanc, Lauzet and Petit Courbu varieties. Tannat was a crossing partner in the four new varieties Achemoyeta, Arinarnoa, Artzebat and Ekigaïna. There is also a light berry variety called Tannat Gris.
