The variety belongs to wine grape types intended exclusively for winemaking. The letter "T" in its name indicates berry color — tinto, which corresponds to red grapes.
The origin of the variety is linked to Portugal, and its genetic lineage is attributed to a cross between Alfrocheiro Preto and Airén. Detailed agronomic characteristics, such as ripening periods or yield indicators, are absent in open reference sources because the variety is not widely distributed and is considered a minor one.
