Arnaldo Rivera's radical cooperative vision realised in Barolo Undicicomuni 2025
In Barolo, greatness as long been tied to the cru: wines born from a singular plot, each expressing its identity in isolation. Arnaldo Rivera spent the last decade pursuing the opposite idea – not only to isolate Barolo into fragments, but to reveal its full breadth and complexity through a single cuvée.
With the 2025 harvest, that vision is complete. For the first time, Barolo Undicicomuni brings together plots from all 11 communes in the appellation – a mosaic of 25 sites in one wine – making it the only Barolo to span the denomination in its entirety.
The 2025 harvest marks the culmination of this singular vision. For the first time, Undicicomuni will bring together plots from all 11 communes in Barolo, a mosaic of 25 sites captured in one wine. This embodies the collective view that blending, rather than separation, can become the highest expression of terroir.
Undicicomuni is the flagship of the Arnaldo Rivera cooperative, headed by its namesake who made the wine alongside his work as a schoolteacher and mayor of Castiglione Falletto. Established in 1958, it was built on a single conviction: that the future of the Langhe depended on protecting growers collectively, preserving vineyard heritage and ensuring entire communities could prosper from the wine they produced. That spirit still defines the project today.
Through decades-long relationships across the appellation, Arnaldo Rivera has assembled holdings that no single estate can match. The result is not a uniform wine but an orchestral one: Serralunga's structure, La Morra's perfume, Monforte's depth, Verduno's elegance – each voice distinct, each contributing to a larger composition.
Recent additions have sharpened the blend's symbolic weight. Villero, Rocche dell'Annunziata, and Cannubi – perhaps Barolo's most storied vineyard – now feature, the latter's vines planted in 1946 and farmed for over three decades by Paolo Scavino before being entrusted to Arnaldo Rivera by a grower who believed the site belonged within a collective vision.
Undicicomuni is ultimately a wine about culture as much as geography – a statement that a great wine region is built not by individual vineyards alone, but by the people, histories and shared traditions that connect them.
