The white grape variety originates from Portugal. Synonyms are Cachorrinho, Casarinho and Uva de Cão. It is possibly identical to the variety Sercial (with synonym Uva Cão) or a variety thereof. It is a parent of the new varieties Malvasia Branca de São Jorge and Sercialinho. The variety is grown in tiny quantities in the Centro and Norte regions. In 2016, 0.4 hectares of vineyards were designated under the name Uva Cão (Kym Anderson statistics).
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
