The white grape variety (also Carignan Branco) originates from France. It is a colour mutation of the red Mazuelo with the synonym Cariñena. But the variety is not called Mazuelo Blanc (as one might think). The late ripening vine is very susceptible to powdery mildew. It produces full-bodied, acidic white wines with citrus aromas. Under the name Carignan Blanc, it is cultivated in the South of France and in 2010 a total of 411 hectares were planted. The rose-berry mutation Carignan Gris is cultivated on one hectare. Under the name Cariñena Blanca (Carinyena Blanca, Samsó Blanco) 2,650 hectares were registered in Spain in 2010. The variety occupied a total of 3,061 hectares of vineyards in 2010; almost three times the amount compared to 2000. This puts it in 143rd place in the worldwide grape variety ranking.
