By the end of World War II, Brunello di Montalcino had developed a reputation as one of Italy's rarest wines. The only commercial producer recorded in government documents was the Biondi-Santi firm, which had declared only four vintages up to that point—1888, 1891, 1925, and 1945. The high price and prestige of these wines soon encouraged other producers to emulate Biondi-Santi's success. By the 1960s there were 11 producers making Brunello, and in 1968 the region was granted "Denominazione di Origine Controllata" (DOC) status. By 1970 the number of producers had more than doubled to 25, and by 1980 there were 53 producers. In 1980, the Montalcino region was the first Italian wine region to be awarded "Denominazione di Origine Controllata e Garantita" (DOCG) designation. By the turn of the 21st century, there were nearly 200 producers of Brunello di Montalcino, mostly small farmers and family estates, together producing nearly 330,000 cases a year.
