The white grape variety originates from Spain. Synonyms are Forcallat, Forcayat and Luisa Blanca. Its parentage is unknown. However, it should not be confused with the Airén variety (with the synonym Forcallat Blanca), with which it has great morphological similarities. It is also not a colour mutation of the red variety Forcallat Tinta. It is cultivated in the regions of Extremadura, Castilla-La Mancha, Murcia and Valenciana. In 2016, 80 hectares of vineyards were designated under the name Luisa Blanca (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.
