Alvarelhão is a red wine grape grown in northern Portugal.
[4] It is one of the authorised varieties in the Galician wine regions of Rías Baixas DOP and Ribeira Sacra.
It is possible that some vines have been misidentified, as the University of California, Davis clone Alvarelhão FPMS 02 has now been confirmed as a Touriga Nacional.
Having evolved in the Dão, the vine is both rough and hardy, having strong defenses against temperature extremes and inclement weather.
[5] German sources, including de:Brancelho, refer to a Brancelho grape used in Vinho Verde whose synonyms include Alvarelhão Ceitão, Varancelho and Verancelha.
