The red grape variety comes from Italy. Synonyms are Bursôn, Longanesi and Negretto Longanesi. In 1913 Antonio Longanesi (1854-1934) bought a property in the municipality of Bagnacavallo, west of Ravenna in Emilia-Romagna. An old vine was then found here, which was climbing up an old oak tree. His grandson Antonio (*1921) propagated it and made wine from it for personal use for many years. It was not until 1956 that his brother Pietro (1931-1999) used the wine as a blend for commercial use. Finally, in 1999, it was included in the official register of varieties with the name of the family. This very old variety has been cultivated in the area for at least 200 years and had been forgotten over time. According to DNA analyses it is not identical to other known varieties. Some local historians hypothesize that it was imported from Spain by mercenaries of the Pope, while others assume that it was selected from local wild vines.
