The white grape variety originates from Portugal. Synonyms are Trajadura Branca, Trincadeira (Portugal); Treixadura, Treixadura Blanca, Trincadente, Verdello Rubio (Spain). It should not be confused with the varieties Trincadeira das Pratas, Trincadeira Preta or Verdello, despite seemingly suggestive synonyms. The parentage is unknown. According to DNA analyses, it is closely related to the Portuguese varieties Arinto, Azal Branco and Loureiro. It is also frequently blended with these varieties. It was a crossing partner (under the name Treixadura) in the new varieties Abaca and Abadesa. The medium-maturing, high-yielding vine is susceptible to botrytis and both types of mildew.
For my many years of work as an editor with a wine and culinary focus, I always like to inform myself about special questions at Wine lexicon. Spontaneous reading and following links often leads to exciting discoveries in the wide world of wine.
