Ampelographers believe that Bubbierasco likely originated around the town of Saluzzo, in the Cuneo province, where its two parent varieties, Bianchetta di Saluzzo and Nebbiolo, have both been grown. In the early 21st century, DNA analysis showed that Bubbierasco was likely a natural crossing of the white Bianchetta and red Nebbiolo varieties.[1]
Today Bubbierasco is almost exclusively cultivated in the province of Cuneo in Piedmont with most plantings found in the Val Bronda region near Saluzzo.[1]
