Probably native to northern Portugal and still grown in the Douro and Minho and used in vinho verde. Brought across the border and today more famous as one of the grapes (known as treixadura) grown in Galicia, Spain, where it’s used in the wine regions of Ribiero and Rías Baixas. Makes dry, fresh whites with a slightly exotic character. Sometimes blended in small amounts (along with loureira) into albariño. In Portugal, it is known as trajadura and is part of the blend in vinho verde.
