This grape variety comes from a natural genetic mutation found in a single cane of a red Tempranillo vine, discovered in an old vineyard in Murillo de Río Leza (La Rioja) in 1988. Clusters are medium-sized and loose, and the berries are also medium-sized and slightly flattened. It is late both at bud break and in arriving at veraison but it ripens early. Total acidity remains high, with high levels of malic acid.
Its wines have a high concentration of volatile compounds with fruity aromas. Its wines offer excellent sensory characteristics, just like the red Tempranillo. They are yellow-green with characteristic intense aromas of bananas and citrus and tropical fruit, underscored by floral and terpene notes. Well-balanced in the mouth, with medium-long structure and persistence. It does not exist anywhere else in the world.
