The story

The Name on the Label

The Marengo family had farmed Brunate for five generations before the vineyard's name appeared on a bottle. In 1974, they bottled a Barolo with Le Brunate printed on the label. It was not a regulation and it was not routine practice in La Morra at the time. The decision was a private one: the fruit from that parcel had been consistently distinct, harvest after harvest, and the family chose to make that distinctiveness visible to anyone who wanted to find it again. They then waited. Twenty-three years passed, through Barolo's slow international rise and a full generational shift in the family, before they made the same decision for Bricco delle Viole, naming that cru on the label for the first time with the 1997 vintage. The two dates now sit quietly on two different bottles, a generation apart, both made from hillsides the family had been farming since before either label existed.

At A Glance

The Producer

Mario Marengo is a family estate in La Morra, a commune at the north-western edge of the Barolo zone in Piedmont. Two vineyards sit at the centre of everything it does: Brunate, a prestigious cru straddling La Morra and Castiglione Falletto, and Bricco delle Viole, a high-altitude site in the Barolo commune itself. Both have been in the family's hands for five generations.

The estate was founded in 1899. Marco Marengo runs it today with his wife Jenny and their son Stefano, a wine technician who represents the next generational step in a family that has farmed these hillsides continuously since the nineteenth century. Marco's approach is direct: the vineyard comes before the cellar. What the parcels produce shapes the wine; the cellar exists to preserve that, not to redirect it.

The range includes two single-cru Barolos, a multi-vineyard base Barolo, a Barolo Riserva, and a supporting trio of Dolcetto d'Alba, Barbera d'Alba, and Nebbiolo d'Alba from Roero.

Place

La Morra is the largest commune in the Barolo denomination by vineyard area, and it sits on predominantly Tortonian soils: Helvetian-era calcareous marl and clay laid down millions of years before the sandstone formations that define the Serralunga side of the appellation. Those soils tend to give Nebbiolo earlier floral lift and a softer, more approachable tannic frame than the harder easterly communes. La Morra Barolos typically open sooner and carry more violet and rose character in youth.

Brunate, the estate's most important vineyard, sits on a south-facing slope between La Morra and Castiglione Falletto. Bricco delle Viole lies at higher altitude in the Barolo commune proper, where the extra elevation gives the Nebbiolo more acidity and a longer growing season. Valmaggiore, the source of the estate's Nebbiolo d'Alba, is in Vezza d'Alba across the Tanaro river in the Roero, a different geological and climatic world from the Langhe.

Soil And Site

The Brunate and Bricco delle Viole parcels sit on Tortonian calcareous marl, the pale, crumbly clay-limestone soils that run through the heart of La Morra. These soils drain well but retain enough moisture to buffer dry summers. Some vines in these parcels are up to 70 years old, their root systems reaching deep into the marl and drawing from a more stable soil profile than younger plantings.

In the rows between the vines, grass is retained rather than removed. Vines are trained on the Guyot system. Farming is classified as integrated and sustainable.

Story

The estate has been in the Marengo family since 1899, more than a century before the Barolo denomination carried the international weight it does today. Four generations of the family made wine in La Morra through the twentieth century, farming the same parcels as the region changed around them.

The clearest mark of that continuity is on the label. In 1974, the family bottled their Barolo from Brunate with the vineyard name printed on the front: Le Brunate. It was not a regulatory requirement. Single-vineyard designation was not yet standard practice in La Morra, and the family named the cru on the label. Twenty-three years passed before they made the same decision for Bricco delle Viole, with the 1997 vintage. The gap between those two labelling moments runs through almost a quarter-century of harvests, family change, and Barolo's rise to international attention.

In 2011, the family completed a new cellar, the first major infrastructure upgrade in the estate's modern era. The building changed the working conditions; it did not change the farming philosophy. Marco Marengo has remained committed to the same principle: decisions made in the vineyard determine the wine, and the cellar's job is to follow.

Vineyards And Cellar

The oldest vines in Brunate and Bricco delle Viole reach 70 years. Age matters for Nebbiolo because older vines produce smaller, more concentrated clusters with more consistent ripening across a large parcel. Guyot training keeps the vine's energy focused through a single cane, limiting yield. Grass left in the aisles between rows reduces soil compaction and supports the microbial health of the ground.

For Barolo Brunate, fermentation is spontaneous with indigenous yeasts in stainless steel, and maceration runs for 14 days. That maceration length extracts firm tannin and colour without pushing the wine into over-extraction; the stainless steel keeps the fruit clean and direct. The 2011 cellar gave the team a purpose-built space to carry out this work at the right temperature and scale.

Barbera d'Alba goes into French-oak barriques for eight months, picking up some rounding oak texture while keeping the grape's natural acidity intact.

Wines

The estate makes two single-cru Barolos that are genuinely different from each other, a fact worth understanding before choosing between them.

Barolo Brunate is 100% Nebbiolo from the Brunate cru, fermented with indigenous yeasts on a 14-day maceration in stainless steel. It is the austere wine in the range: firm tannin, pronounced mineral character. It is built for a decade or more in bottle.

Barolo Bricco delle Viole is also 100% Nebbiolo, from the high-altitude Bricco delle Viole site in the Barolo commune. The altitude gives the wine higher acidity than Brunate and more immediate aromatic lift: floral and spice notes that come forward earlier. Despite the elevation, it is the more approachable of the two crus in youth.

The base Barolo blends fruit from four La Morra vineyards. It carries the commune's typical floral and soft-tannic character without the mineral austerity of Brunate or the aromatic cut of Bricco delle Viole, and it gives access to the estate's Nebbiolo work at an earlier drinking window. The Barolo Riserva is also in the range.

Barbera d'Alba spends eight months in French-oak barriques, which adds a layer of vanilla and body to Barbera's naturally high acidity and dark cherry fruit. Dolcetto d'Alba rounds out the red range. The Nebbiolo d'Alba comes from the Valmaggiore vineyard in Vezza d'Alba in the Roero, across the Tanaro from the Langhe, where lighter soils give the Nebbiolo a different weight and texture from the Barolo wines.

In The Glass

Barolo Brunate opens slowly. On the nose it tends toward dried rose, tar, and iron-edged mineral notes rather than fresh fruit. In the mouth the tannins are firm and chalky, the acidity is firm, and the mid-palate has a concentrated but tight quality that calls for patience. The finish is long and dry. Give it five years at minimum; the best vintages want ten or more.

Bricco delle Viole presents differently from the first pour. The aromatic register is more immediately floral, with violet and spice coming forward before the mineral notes arrive. The acidity is higher and the tannins are present but less dense than Brunate. In the mouth there is more lift and less weight, and the wine reaches a pleasurable drinking window sooner without losing the Nebbiolo backbone.

The base Barolo carries the La Morra commune character in a more open frame: rose petal, light tar, and soft tannin from the multi-vineyard blend. It is the wine in the range that can be opened within four to six years of the vintage.

A Bottle To Understand It

Start with Barolo Brunate. It is 100% Nebbiolo from a parcel the family has farmed for five generations, fermented with the vineyard's own yeasts, macerated for 14 days, and built without oak influence. Nothing in the glass is softened for early appeal.

Anecdote

The Marengo family had farmed Brunate for five generations before the vineyard's name appeared on a bottle. In 1974, they bottled a Barolo with Le Brunate printed on the label. It was not a regulation and it was not routine practice in La Morra at the time. The decision was a private one: the fruit from that parcel had been consistently distinct, harvest after harvest, and the family chose to make that distinctiveness visible to anyone who wanted to find it again. They then waited. Twenty-three years passed, through Barolo's slow international rise and a full generational shift in the family, before they made the same decision for Bricco delle Viole, naming that cru on the label for the first time with the 1997 vintage. The two dates now sit quietly on two different bottles, a generation apart, both made from hillsides the family had been farming since before either label existed.

Final Word

Mario Marengo is a small La Morra estate with a very long memory. Two parcels, two quite different Barolos, four generations of unbroken farming, and a philosophy that has never shifted its centre of gravity from vineyard to cellar. Brunate is the wine to follow over time.
