Bariadorgia


Bariadorgia (also known as Carcajolo blanc) is a white Italian/French wine grape variety that likely originated on the island of Sardinia but today is only found in limited planting on Corsica. Despite similarities in synonyms, Bariadorgia/Carcajolo blanc is not a color mutation of the red Spanish wine grape Parraleta which is also known as Carcajolo near on Sardinia.

While Bariadorgia was first mentioned in 1822 growing in the commune of Sartène on Corsica under the synonym Carcajola, ampelographers such as Gustave Foëx of the Viticultural College at the University of Montpellier and colleague of Pierre Viala have speculated since at least the early 20th century that grape was likely introduced from neighboring Sardinia. The commune of Alghero on the northwest coast of the island has been mentioned as the possible home of Bariadorgia.

While the origins of the name Bariadorgia is unclear, the synonym Carcajolo is believed to be derived from the Italian word caricagiola which means "heavily laden" and could be a reference to the large clusters that the Bariadorgia vine produce which can be heavy and weigh down the cane as the grapes near harvest.

In the early 21st century, DNA analysis showed that Bariadorgia was identical to plantings of Gregu bianco planted around the Campidano region of Sardinia. DNA profiling has further shown that the grape is not related to the Corsican grape Biancu Gentile nor is a color mutation of the Spanish wine grape Parraleta which is known as Carcajolo near on Sardinia.
