Why it matters
The producer
Federico Oberto spent 35 years in the cellar at Renato Ratti's winery in La Morra, one of the estates that shaped how Barolo was understood and sold in the second half of the twentieth century. He arrived in 1970, when Ratti was still alive and actively arguing for a more accessible, earlier-drinking style of Barolo. Federico stayed through Ratti's death in 1988, through the years Massimo Ratti ran the estate, and kept going until 2005. When three friends bought the old Oberto family vineyard in Berri two years later and set up Trediberri, they brought Federico in to run the cellar.
The name makes the origin legible: tre, three founders, plus Berri, the hamlet where the vines grow. The Oberto family parcels at Rocche dell'Annunziata and Torriglione had surrounded the site for generations. Federico was not arriving somewhere new. He was returning to a few hundred metres from where his family's oldest vines had always grown.
Place and vineyards
Where the wines begin
Berri is a small hamlet at the western edge of La Morra, itself a commune and appellation at the western margin of the Barolo DOCG zone. The Tanaro river runs close below. La Morra sits on soils formed from Tortonian-era deposits, softer and more sand-rich than the compact Helvetian marls that dominate Serralunga d'Alba and Castiglione Falletto on the eastern side of the denomination.
At Rocche dell'Annunziata, sand predominates near the valley floor and the soils become loamier as the slope rises. Sandy, lower-density soils drain quickly, warm early in the growing season, and give Nebbiolo a more open aromatic profile and softer tannin than the dense marls further east. La Morra Barolo tends toward red fruit, rose, and violet rather than the tar and leather notes associated with the eastern communes, and it softens earlier in bottle.
In the cellar
Vineyards and cellar
Trediberri does not follow a fixed cellar protocol. Fermentation vessels, maceration length, and ageing format are chosen vineyard by vineyard and vintage by vintage, from concrete to stainless steel to large botti grandi, based on what the fruit and the year require. The Baroli generally macerate on the skins for at least three weeks in concrete, which extracts colour, tannin, and aromatic depth without the oxidative softening that comes from other approaches. They then age for two years in large botti, the traditional large Slavonian or French oak casks that give slow oxygenation without adding oak flavour.
The Langhe Nebbiolo is handled differently: fermented in concrete or stainless steel and bottled earlier for a lighter, more immediate character. The Bricco Mollea Dolcetto and Nebbiolo from Vicoforte follow a separate logic determined by their high-altitude growing conditions and the different ripeness profile that 600 metres produces.
Wines to know
The range in view
The range has three strands.
The Langhe Nebbiolo DOC is varietal Nebbiolo from La Morra parcels. It is pale in colour, fragrant, with rose petal and red cherry on the nose and a light, low-tannin palate designed for early drinking. The estate recommends serving it lightly chilled. This is not a simplified Barolo but a deliberately different wine: quicker, fresher, and built for a meal rather than a cellar.
A useful way in
A bottle to begin with
The Barolo Rocche dell'Annunziata DOCG is the bottle to start with. It is single-MGA Nebbiolo from La Morra's sandier soils, from vines planted in 1955, 1961, and 1999, made by a cellar director whose understanding of how La Morra Nebbiolo behaves runs back to 1970. The wine sits between the lighter freshness of the Langhe Nebbiolo and the heavier extract you find from Barolo's eastern communes: it has real depth and tannic grip, but the aromatics are open and the palate is generous enough that a bottle opened five years after vintage gives you something complete.
