The white grape variety originates from Portugal. It probably has its origin from this area, according to the second main name Arinto de Bucelas. Others are Asal Espanhol, Assario Branco, Arintho, Arinto Cachudo, Arinto Cercial, Arinto d'Anadia, Arinto Galego, Arintho, Azal Espanhol, Boal Cachudo, Chapeludo, Pedernã, Terrantez da Terceira and Torrontés. The parentage is unknown. The vine must not be confused with the varieties Arinto de Colares, Bical (Arinto de Alcobaça), Dorinto (Arinto do Douro), Folgasão, Terrantez da Terceira, Loureiro (Arinto Branco), Malvasia Fina (Arinto do Dão), Sercial (Arinto dos Açores) or Tamarez (Arinto Gordo), despite seemingly suggestive synonyms or morphological similarities. There is no relationship with the red Tempranillo variety (Arinto Tinto). The Arinto Roxo variety is a somatic mutation with reddish berries. A direct descendant is the Tinta Fontes variety, which was created by presumably natural crossing.
