The white grape variety comes from Spain
. Synonyms are Forcallat and Forcayat. The parentage (parenthood) is unknown. Confusingly, it is also a synonym (also Forcallada, Forcallat) for the Airén
variety, with which it has great morphological
similarities. It is also not a colour mutation of
the red variety Forcallat Tinta
. However, the Forcallat Blanca variety is no longer significant.
