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 is unknown. But it must not be of the variety Arinto (Arinto de Bucelas) or the 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 ripening vine is susceptible to real and false mildew, It produces fresh fruit white wines with a citrus aroma. The variety is in the range Douro grown. In 2010, 115 hectares of vineyards were shown (Kym Anderson ).
