Roccheviberti

Castiglione Falletto estate farming 4.5 hectares of Nebbiolo, Barbera and Dolcetto across three Barolo crus since 1946. Claudio Viberti, third generation, began estate-bottling in 2003.

The producer

Roccheviberti sits in the village of Rocche within the commune of Castiglione Falletto, a Langhe hill town whose name appears on some of the most sought Barolo in the appellation. The estate covers 4.5 hectares of Nebbiolo, Barbera and Dolcetto spread across three named crus, and the Viberti family has farmed these parcels since 1946. Claudio Viberti, the third generation to tend the vines, released his first vintage under the Roccheviberti label in 2003.

What makes the estate worth understanding is not scale but geology. Two of its three crus, Rocche di Castiglione and Bricco Boschis, face different directions, sit at different altitudes and carry soils so unlike each other that Claudio eventually decided the only honest thing to do was bottle them separately. A buyer who opens both bottles from the same village, the same grower and the same vintage is tasting Castiglione Falletto's two dominant soil types poured from a single 4.5-hectare estate.

Known for

Single-cru Barolo from Rocche di Castiglione (limestone and tuff, aromatic, soft tannins) and Bricco Boschis (heavy clay, firm grip, long ageing trajectory), plus a village-blend Vecchie Viti di Castiglione.

Notable facts

The story

The Year Claudio Split the Hill

For years Claudio Viberti harvested Bricco Boschis and Rocche di Castiglione separately but sent both parcels into the same barrel programme. He knew the two vineyards tasted different: the clay on Bricco Boschis pulled toward darker colour and harder grip, while the limestone and tuff at Rocche lifted the nose and softened the tannins. In 2014 he stopped averaging them. He vinified the Bricco Boschis fruit as a named single-cru Barolo for the first time in 2014. A taster who opens the Rocche di Castiglione and the Bricco Boschis side by side in the same evening is effectively tasting the two soil types that Castiglione Falletto is built on, poured from the same small estate.

At A Glance

The Producer

Roccheviberti sits in the village of Rocche within the commune of Castiglione Falletto, a Langhe hill town whose name appears on some of the most sought Barolo in the appellation. The estate is small: 4.5 hectares of Nebbiolo, Barbera, and Dolcetto spread across three named crus. The Viberti family has farmed these parcels since 1946, and Claudio Viberti, the third generation to tend the vines, released his first vintage under the Roccheviberti label in 2003.

What makes the estate worth understanding is not scale but geometry. Two of its three crus, Rocche di Castiglione and Bricco Boschis, face different directions, sit at different altitudes, and carry soils so unlike each other that Claudio eventually decided the only honest thing to do was bottle them separately. A drinker who opens both bottles from the same village, the same grower, and the same vintage is tasting the Langhe's geological argument with itself.

Place

Castiglione Falletto occupies a central position in the Barolo zone, physically and stylistically. The village sits between the heavier clay and limestone of Serralunga to the east and the more calcareous, sand-mixed soils of La Morra to the west. Barolo's legal production area covers eleven communes, and Castiglione Falletto produces wine that sits between those two poles: enough grip for ageing, enough aromatic lift to drink sooner than a pure Serralunga.

Roccheviberti's two primary crus each pull in a different direction. Rocche di Castiglione rises to 300-350 metres with an east-southeast exposure, catching the morning sun. Bricco Boschis faces west at 200-300 metres. The altitude difference is modest; the soil difference is not. Rocche carries limestone with sand and tuff. Bricco Boschis carries heavy clay. Those two substrates translate directly into two distinct Barolo profiles, and the range is built around that fact.

Soil And Site

Rocche di Castiglione is a small, steep cru whose limestone-and-tuff base is lightened by sand. The combination drains well and warms quickly under morning sun. The Rocche vines average 40 years old and grow exclusively Nebbiolo for Barolo. Limestone and tuff tend to produce wine with clear aromatic definition and tannins that soften earlier than clay-grown Nebbiolo.

Bricco Boschis is a larger vineyard at lower elevation, facing west on heavy clay. Clay retains moisture through dry summers, adds colour depth to the wine, and produces tannins that grip harder and take longer to knit. The Roccheviberti parcels within Bricco Boschis include Nebbiolo and Dolcetto, with Dolcetto in Vigna Malera.

Mariondino, the third cru, is usually blended with Rocche di Castiglione or Bricco Boschis fruit.

Story

The Viberti family began farming in Rocche in 1946. For the first half-century the fruit went to other producers or into bulk wine. Claudio, who grew up watching his father and grandfather work the same parcels, chose a different path. In 2003 he released the first Roccheviberti-labelled vintage.

He continued through subsequent vintages, refining the cellar programme, and in 2014 made a more consequential decision: he separated Bricco Boschis from the estate blend and bottled it as a named single-cru Barolo for the first time. That choice committed him to running two structurally different Barolos in the same range, from the same 4.5 hectares, with the same traditional cellar approach applied to two very different raw materials.

Vineyards And Cellar

All the Nebbiolo at Rocche di Castiglione goes to Barolo. The vines are mature, averaging 40 years, and the cru's steep slopes mean low natural yields. Fermentation happens in temperature-controlled steel tanks, which preserves the aromatic character that limestone-and-tuff Nebbiolo develops. Ageing moves to French oak barrels. The approach keeps the cellar from adding flavour on top of the vineyard: oak provides oxygen exchange and gradual tannin softening rather than vanilla or toast character.

The Langhe Nebbiolo, the entry wine in the range, ages 18 months in French oak casks and at least 6 months in bottle. That extended wood contact gives a wine at this level more presence than a quick-aged Nebbiolo, though it stays lighter and less concentrated than the single-cru Barolos.

The Bricco Boschis parcels include Dolcetto in Vigna Malera.

Wines

The range has five labels, and the architecture follows the crus rather than a hierarchy of price alone.

Barolo Rocche di Castiglione is the estate's most aromatic wine. Nebbiolo from the limestone-and-tuff hillside at 300-350 metres produces a Barolo with clear cherry and dried rose on the nose, a mid-palate that is firm but not heavy, and tannins that resolve to a silky finish earlier than the clay-grown wines. The east-southeast exposure means morning sun and cooler afternoons, preserving acidity and fragrance.

Barolo Bricco Boschis is the structural counterpoint. Heavy clay at 200-300 metres on a west-facing slope produces Nebbiolo with deeper colour, a broader tannic frame, and a longer ageing trajectory. The fruit is darker, the finish drier, and the wine needs more time in bottle to open.

Barolo Vecchie Viti di Castiglione is the village-level blend, drawing from multiple Castiglione Falletto parcels. The 2021 bottling drew praise for its commune-level synthesis: red cherry, dried herbs, and polished tannins from Nebbiolo across several sites. It sits between the two single-cru extremes in body and ageing need.

Langhe Nebbiolo is the entry wine, made from Nebbiolo and aged in French oak casks. It gives earlier access to the grape's floral character and light red fruit without demanding the cellaring the Barolos prefer.

Barbera d'Alba and Dolcetto d'Alba complete the range. The Bricco Boschis parcels include Dolcetto in Vigna Malera.

In The Glass

The Rocche di Castiglione Barolo opens with notes of spice, leather, violet and goudron. In the mouth it has the firm but yielding tannin that limestone-grown Nebbiolo tends to produce, with bright acidity carrying the mid-palate and a finish that stays floral longer than you expect from Barolo. It can be approached within a decade of the vintage; it does not demand the patience the Bricco Boschis does.

The Bricco Boschis Barolo is darker from the moment it is poured: ruby-garnet with more depth, aromas of plum and tobacco, and a grip on the palate that signals the clay in the soil. The clay soil produces more intense color and pronounced tannins, supporting the wine's longevity. Five or more years from a good vintage starts to show what it can do.

Vecchie Viti sits between them in character. The 2021 shows red cherry, dried herbs, and a smooth tannic frame that reflects the village-level blend rather than any single soil type. It is the most accessible of the three Barolos on release.

A Bottle To Understand It

Start with the Barolo Rocche di Castiglione. It is the wine the estate is named for: Nebbiolo from forty-year-old vines on the limestone-and-tuff hillside that defines the village of Rocche. Fermented in steel to preserve aromatic clarity, aged in French oak for gradual softening, it arrives in the glass with dried rose, cherry and a fine, precise acidity that carries the wine through a long finish. The tannins are real but not punishing, and the wine is approachable within a reasonable number of years. Rocche di Castiglione is where Castiglione Falletto's middle character, between Serralunga grip and La Morra perfume, is most legible in a single bottle.

Anecdote

For years Claudio Viberti harvested Bricco Boschis and Rocche di Castiglione separately but treated the fruit the same way once it reached the cellar: both went into the barrel programme together, blended into a single estate Barolo. He knew the two vineyards tasted different. The clay on Bricco Boschis pulled the wine toward darker colour and harder grip; the limestone and tuff at Rocche lifted the nose and softened the tannins. In 2014 he decided to stop averaging them. He separated the Bricco Boschis fruit at harvest and vinified it as a named single-cru Barolo for the first time. The decision gave him two bottles that disagreed with each other in the best possible way. A taster who opens the Rocche di Castiglione and the Bricco Boschis side by side in the same evening is effectively tasting the two soil types that Castiglione Falletto is built on, poured from the same 4.5-hectare estate.

Final Word

Roccheviberti is a family estate where the work of three generations is visible in two bottles. The contrast between Rocche di Castiglione and Bricco Boschis is not a marketing distinction: it is a geological fact that Claudio Viberti decided to make audible in 2014. For a buyer who wants to understand how soil changes Barolo without travelling through multiple producers or appellations, the two single-cru bottles from this one small estate are an unusually direct comparison.
