||The vine was described using a clone from the vineyard of Giuseppe Valenti da Rosolini, located in the municipality of Noto (province of Syracuse), in the 'Belliscale' district. The characteristics found in this vineyard were then compared with those of the 'Calabrese' variety grown in the municipalities of Pachino and Avola, also in the province of Syracuse, with those of the same variety grown in Vittoria, in the province of Ragusa, and with those presented by clones in the ampelographic collection of the Istituto Tecnico Agrario Statale di Catania.
