The Produttori del Barbaresco, founded in 1958, now has 51 members and controls more than 100 hectares (250 acres) of premium Nebbiolo vineyards in Barbaresco. Each family is in full control of its land, growing Nebbiolo grapes with centuries old skill and dedication. 

In great vintages, nine single-vineyard Barbarescos are produced from nine classic premium sites within the Barbaresco village boundaries: Asili, Rabajà, Pora, Montestefano, Ovello, Pajè, Montefico, Muncagota, and Rio Sordo. These are the geographical names of sites where Nebbiolo grapes have always been cultivated. The name of the single-vineyards, the total number of bottles produced, and the name of the owners of the vineyards are marked on the labels.
