The white grape variety originates from the Spain/Portugal border region (Iberian Peninsula). Synonyms are Trajadura Branca, Trincadeira (Portugal); Treixadura, Treixadura Blanca, Trincadente, Verdello Rubio (Spain).

The parentage is unknown. It should not be confused with the varieties Trincadeira das Pratas, Trincadeira Preta or Verdello due to some of the same synonyms. According to DNA analyses, it is closely related to the Portuguese varieties Arinto, Azal Branco and Loureiro. It is also often blended with these. It was a crossing partner (under the name Treixadura) in the new varieties Abaca and Abadesa.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
