The red grape variety comes from Italy. Synonyms are Bigia, Grisa, Grisa di Cumiana and Uva Bigia. It should not be confused with the Grisa variety, which is hardly cultivated any more. According to DNA analyses carried out in 2006, there is a parent-offspring relationship with the Avarengo variety. However, the parentage (parenthood) is unknown. The medium to late-maturing, yield-insecure vine is relatively resistant to fungal diseases, but tends to trickle. It produces simple red wines, which are usually blended with other local varieties. The variety is also used as a table grape. It is cultivated in Piedmont in the provinces of Torino and Cuneo. No stock was recorded in 2010 (statistics Kym Anderson).
