The white grape variety originates from Portugal. Synonyms are Carnal, Dependura, Diego Alves, Diogalves, Fernan Fer, Formosa, Formosa Dourada, Formosa Portalegre, Mantúa, Mantúo, Montúa, (second main name), Montúo, Pendura, Pendura Amarela (Portugal); Eva, Villanueva (Spain). It should not be confused with either Beba (Eva) or Palomino (Diagalves), despite seemingly suggestive synonyms or morphological similarities. According to DNA analyses carried out in 2013, it is a presumed natural cross Hebén x Dedo de Dama. However, this is based on only 20 DNA markers (see Molecular Genetics for more information). Diagalves was crossing partner of the new varieties Alvarinho Liláz, Castelo Branco, Deliciosa, Moscatel Rosado, Rio Grande and Seara Nova. This late-ripening vine is susceptible to botrytis, esca, small berry and trickling. It yields low alcohol and low acid white wines of simple quality with a grassy aroma. The variety is also used as a table grape. It is cultivated in the Portuguese areas of Alentejo, Algarve and Tejo, among others. In 2016, a total of 1,090 hectares of vines were declared (Kym Anderson).
