The Caracol grape variety is one of the traditional grape varieties on the island of Porto Santo. There are several stories and myths about its potential origin, such as that it was a certain Mr. Caracol who brought and planted it.

António Maçanita's insatiable curiosity led him to analyze the microsatellites, which demonstrates their enormous genetic proximity to the Listrão, with only one differing from a total of 20, which could have the same progenitor or be progenitors of each other.

Regarding the name, research in the old bibliography may also reveal the reason for the name Caracol. Gaspar Frutuoso in 1580 stated: “there are many vineyards, which produce good grapes; Many white snails are created on them, in so many ways that, in parts, they cover the bunch of grapes so much that no berries appear on them.”
