The white grape variety comes from Portugal; it is one of the numerous Boal varieties (see there). Synonyms are Boal, Boal Branco do Algarve, Boal Cachudo, Boal Calhariz, Boal de Alicante, Boal de Calhariz, Boal de Madere and Boal na Madera. According to DNA analyses carried out in 2012, this is a presumably natural cross between Arinto do Dão(Malvasia Fina) x Dedo de Dama. However, this is based on only 20 DNA markers (see molecular genetics). In spite of synonyms and morphological similarities it should not be confused with the mother variety Malvasia Fina (Boal Branco). In 2016 no stock was recorded (Statistik Kym Anderson).

For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
