Treixadura

Treixadura or Trajadura is white Portuguese wine grape variety grown primarily in the Vinho Verde wine region of northeast Portugal and the Galician wine regions of Ribeiro and Rías Baixas in Spain where the variety is known as Treixadura. The grape is primarily a blending variety that adds body and light lemony aromatics to wines. It is most commonly blended with Loureiro and Alvarinho in Rías Baixas while in Ribeiro it is often blended with Torrontés and Lado.
