The white grape variety comes from France. Synonyms are Aouba, Auba, Blanc de Cadillac, Burger, Cadillac and Frontignan des Charentes. It is possibly named after its exact place of origin, the commune of Monbadon in the Gironde. According to DNA analyses carried out in 2000, it is a natural cross between Folle Blanche x Ugni Blanc(Trebbiano Toscano). The medium to late ripening, very high-yielding vine is susceptible to botrytis. It produces acidic, neutral white wines for quick enjoyment. This almost extinct variety is cultivated in France in only small quantities in the Languedoc. In California, it was one of the most widespread varieties, especially in the Central Valley, until the 1950s under the name Burger, from which simple jug wines (bulk wines) were produced in large quantities. Since then, however, the stock has been greatly reduced, as in 2010 there were only 498 hectares of vineyards left. There are also small stocks in Australia.
