The white grape variety comes from Portugal. Synonyms are Trajadura Branca, Trincadeira(Portugal); Treixadura, Treixadura Blanca, Verdello Rubio(Spain). It must not be confused with the varieties Trincadeira das Pratas, Trincadeira Preta or Verdello, even if they appear to be synonymous. 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 (under the name Treixadura) a cross-breeding partner in the new Abaca and Abadesa varieties.
The medium maturing, high-yielding vine is susceptible to botrytis and both types of mildew. It produces straw-yellow, alcohol-rich white wines with aromas of apples, pears, peaches and lemons. The variety is cultivated in Portugal in the Beiras, Douro, Rios do Minho and Vinho Verde areas on 1,171 hectares. In Spain, it is cultivated under Treixadura or Treixadura Blanca in the region of Galicia, mainly in the areas of Monterrei, Rías Baixas, Ribeira Sacra, Ribeiro and Valdeorras on 998 hectares. In 2010, 2,169 hectares were recorded.
