PRE-PHYLLOXERA VARIETALS
The phylloxera plague that devastated Europe in the last third of the 19th century never reached the Canary Islands, which allowed the preservation of its grape varieties.
The varieties of Lanzarote arrived, after the eruptions of the 18th century, from other islands of the Archipelago. They had originally reached the Canary Islands from Andalusia in the early 16th century.
In Lanzarote, most of the varieties described in 1877 by the engineer Barrioso in the report he presented at the National Viticulture Congress of 1878 are still preserved today.
Some are exclusive to the Canary Islands, such as Malvasía Volcánica and Listán Negro; others, like Vijariego, are becoming endemic, since they have almost disappeared in their original region of Andalusia.
The absence of phylloxera makes it possible to plant vines on their own rootstock (pie franco), without the need for grafting, just as it was always done.
