 However, in the early 21st century, DNA profiling showed that the two grapes actually had parent-offspring relationship though it is not yet known which grape is the parent and which is the offspring.This relationship makes Mondeuse noire, which is also known under the synonym "Grosse Syrah", either a grandparent or half-sibling to Syrah.When Mondeuse noire was first introduced to California in the 19th century, some plantings of the vine were misidentified as the Italian wine grape Refosco dal Peduncolo Rosso.
