From the importer:

Brovia’s formidable Barolo "Brovia" epitomizes their classically built yet elegant house style and expresses the full breadth of their enviable holdings. While its composition varies slightly each year depending on yields, it always comprises the following sources: (1) From their holdings in Castiglione Falletto, Brovia produces but one single cask of each cru-designated wine per vintage, directing any extra volume into the Barolo "Brovia." Accounting for 20-30% of the wine's final blend, this spillover comes from vines exceeding 50 years of age in the crus of Rocche di Castiglione, Villero, and Garblet Sue. (2) 70-80% of the Barolo "Brovia" comes from holdings in Serralunga d’Alba, primarily in the cru of Brea with smaller amounts (beginning in 2020) in Gianetto, an east-facing cru which is a natural extension of Brea and yields a wine of similar character. These vines are 20 to 30 years of age on average, the oldest parcels of Brea being used for the single-cru bottling. The Barolo "Brovia" undergoes spontaneous fermentation in a variety of vessels—cement, open-top wood, and stainless steel—and is raised 24 to 30 months in oak botti between 30 and 100 hectoliters in capacity. Afterward, the wine is assembled in a combination of steel and wood for an additional year, being bottled no sooner than 40 months after harvest. This aging process, which is longer than that of the crus (aged solely in 30- to 40-hectoliter casks and bottled after 30 months), allows for a wine slightly more open-knit upon release by design.
