The white grape variety comes from Portugal. Synonyms are Arinto Branco, Arinto Cachudo, Arinto de Trás-os-Montes, Arinto do Douro, Arinto do Interior and Arinto no Douro. The parentage (parenthood) is unknown. However, it must not be confused with the variety Arinto (Arinto de Bucelas) or other numerous varieties with Arinto synonyms. The former main name Arinto do Douro or Arinto no Douro was changed to Dorinto (combination of Douro and Arinto) to avoid confusion. The early maturing vine is susceptible to both types of mildew. It produces fruity white wines with citrus aromas. The variety is cultivated in the Douro area. In 2016, 70 hectares of vineyards were designated (Kym Anderson).
