The red grape variety originates from France. Synonyms are Bordelais Noir, Madiran, Madiron, Mouston, Moustron, Moustrou, Moustroun, Tanat, Tannat Gris, Tannat Noir, Tannat Noir Femelle, Tannat Noir Male (France); Bordelez Beltza (Spain); Bordelez Beltza, Bordeleza Belche (Basque Country); Harriague (Uruguay).
The variety was first mentioned in documents in 1783 under the name Tanat in the French département of Hautes-Pyrénées, which is why this can be assumed to be the probable area of origin.
The ancestry (parentage) is unknown. According to DNA analyses, there is possibly a parent-offspring relationship with the Manseng Noir variety. Tannat was a crossing partner in the four new varieties Achemoyeta, Arinarnoa, Artzebat and Ekigaïna. It is also a parent of the variety Négret de Banhars, which was created by natural crossbreeding. There is also a light berried variety called Tannat Gris.
