The winery at Castiglione Falletto was built in 1982 and was created to vinify grapes coming from the finest vineyards of the Barolo denomination. It was extended in 2000, with the construction of the futuristic glass Cube, which provides a perfectly integrated contrast of modern design against the profile of the hills that surround it. Bricco Rocche is the home for vinifying and aging some of the most prestigious crus of the region, as well as that of its namesake: Brunate from La Morra, Prapò from Serralunga d’Alba, and Cannubi San Lorenzo from Barolo.

This wine takes its name from the prestigious Prapò vineyard which was one of the first properties owned by the Ceretto family in Barolo. This vineyard has one of the best exposures on the eastern slopes of Serralunga d'Alba, a world-renowned commune within Barolo. The soils have a high percentage of silt and clay which means the wines produced have a distinct and rare punchiness. Ceretto owns 2.4 hectares (of the 8.5 hectares of the total sub-zone) with a high average age of the vines, planted in the '70s.

Barolo Prapò comes from Serralunga d'Alba and is, as expected, the most powerful and structured of the various single-vineyard wines from this ambitious winery. At the same time, it is also the most closed off at the beginning and, with its introverted nature, made for a long maturing period. This site is one of the last where the grapes ripen, so they have plenty of time to develop slowly and carefully each year.
