The white grape variety comes from Spain. Synonyms are Forcallat, Forcayat and Luisa Blanca. The parentage (parenthood) is unknown. However, it should not be confused with the Airén variety (with synonym Forcallat Blanca), with which it has great morphological similarities. It is also not a colour mutation of the red variety Forcallat Tinta. In 2016, no stocks were reported (statistics Kym Anderson).
