The Brezza private estate, with vineyards in Barolo dating back to 1885, takes its name from Giacomo Brezza, who with his father Antonio bottled the first wine of the estate in 1910. The estate lies very close to the centre of Barolo, immersed in the vineyards, as is the nearby Hotel and Restaurant, also property of the Brezza family. The fourth generation of the Brezza family now manages the estate, which extends over twenty-three hectares, eighteen of which are vineyards - fifteen in Barolo, two in Alba and one in Monforte d'Alba.

The original part of the cellar, built in the traditional vaulted style, with exposed brick, was once the area where all cellar operations took place; it is now reserved for the maturation of wine in oak. The largest part of the cellar, which is of more recent construction, is divided into two cellars, the first used for the primary fermentation in temperature-controlled stainless steel tanks. The second cellar is utilised for malolactic fermentation and other operations within the cellar. The cellar for the bottle-aging is located underground where a constant temperature and suitable humidity level are naturally maintained. The total production is approximately 90.000 bottles per year, produced from grapes sourced only from estate vineyards.

The wines, 95% red, are all certified as 'Denominazione Origine Controllata' (DOC) or 'Denominazione Origine Controllata Garantita' (DOCG): Langhe Freisa from the Santa Rosalia vineyard, Dolcetto d'Alba from the Fossati and San Lorenzo vineyards, Barbera d'Alba from the Cannubi and Cannubi Muscatel vineyards, and Nebbiolo d'Alba from the Santa Rosalia vineyard, Langhe Nebbiolo, Langhe Rosso.

Brezza produes four single-vineyard Barolo DOCG wines: Castellero, Cannubi, Sarmassa and Bricco Sarmassa, all historical subzones in the heart of the historic Barolo region. A white Langhe Chardonnay is also produced.
