The white grape variety originates from Portugal. The parentage is unknown. Synonyms are Medock, Rabo de Ovelha, Rabo de Ovelha Vinho Verde, Rabo de Ovelha nos Vinhos Verdes, Rabo de Ovelha Tinta and Rabo de Ovelha Tinto. It should not be confused with the Rabo de O velha variety due to apparent synonyms or morphological similarities. It is grown in the Alentejo (24 ha) and Algarve (0.2 ha) areas, as well as in the Centro (54 ha) and Norte (7 ha) regions. In 2016, a total of 86 hectares of vines were designated in Portugal (Kym Anderson).
