Ratti

La Morra Barolo estate founded in 1965 by Renato Ratti, the producer who drew the first map of Barolo's individual subzones and introduced cru labelling to the Langhe. Now run by Pietro Ratti from a 50-hectare, six-estate portfolio across four communes.

The producer

Ratti sits at Frazione Annunziata in La Morra, on the northwestern edge of the Barolo zone in Piemonte. Renato Ratti returned to Italy in 1965, bought a parcel in the Marcenasco locality, and bottled his first Barolo under his own name. What set that act apart was the argument behind it: before Ratti published his map of the Barolo zone, growers blended across communes and sold without vineyard attribution. He divided the appellation into its constituent subzones, named each one by soil type and character, and printed the result. The Menzione Geografica Aggiuntiva system that now governs vineyard labelling across Barolo came decades later, but Ratti's map gave the conversation its first shared language.

Pietro Ratti took over in 1988 and has run the estate since, keeping the founding principles intact: named crus, subzone differentiation, and bottle ageing used to soften Nebbiolo's tannin without sacrificing the wine's capacity to develop. The vineyard portfolio has grown to around 50 hectares across six estates in La Morra, Mango, Costigliole d'Asti, and Dogliani, each site in genuinely different terrain and appellation. Marcenasco remains the anchor Barolo, made entirely from Nebbiolo grown on calcareous-clay ground in La Morra. Serradenari, a second La Morra cru at higher altitude, debuted with the 2019 vintage and reached the market in 2023.

The story

The Map That Named Barolo

When Renato Ratti returned to the Langhe in 1965, the Barolo zone had no public map of its own. Growers knew their parcels by name and memory, but the subzones had never been drawn, labelled, and printed for anyone outside the valley to read. Ratti sat down and made one. He divided the zone into its constituent localities, named each one, noted soil types and characters, and published the result as a physical document. It was not a regulatory submission or a commercial proposal; it was a cartographer's argument that place mattered and deserved to be visible on a label. The Menzione Geografica Aggiuntiva system that legally recognises vineyard names on Barolo labels came into being decades later, but the map Ratti drew gave the conversation its first shared language. Every bottle of Barolo that carries a vineyard name is, in a small way, still working from that document.

The Producer

Ratti sits at Frazione Annunziata in La Morra, a village on the northwestern edge of the Barolo zone in Piemonte. The cellar has been at this address since Renato Ratti returned to Italy in 1965, bought a parcel in the Marcenasco locality of La Morra, and bottled his first Barolo under his own name. What made that act unusual was not the wine itself but the argument it carried: Renato Ratti believed that Barolo's individual subzones produced wines worth distinguishing, and he drew a physical map to prove it.

That map changed how Barolo was understood. Before it, the appellation's growers blended across communes and sold without vineyard attribution. Renato Ratti published the first systematic cartographic division of the zone, identifying subzones by name, soil type, and character. The Menzione Geografica Aggiuntiva system that now governs vineyard labelling across Barolo came decades later, but the conceptual ground was prepared by that early printed map.

Pietro Ratti took over the estate in 1988 and has run it since. The vineyard portfolio has grown to around 50 hectares across six estates in La Morra, Mango, Costigliole d'Asti, and Dogliani. The cellar was renovated in 2005, its lines shaped to follow the contour of the hill rather than announce themselves across it.

Place

La Morra is the westernmost of Barolo's main communes, sitting on calcareous-clay soils that give Nebbiolo a softer, rounder character than the Helvetian marl and sandstone of Serralunga d'Alba or the compact Tortonian soils of Castiglione Falletto. Wine from La Morra tends to open earlier, with fuller fruit and less severe tannin in youth, though it still ages for decades on good vintages. Marcenasco is a locality within La Morra, and the Barolo that carries its name reflects this commune character: Nebbiolo grown on calcareous clay, vinified and then given time in bottle before release.

The six estates beyond La Morra sit in genuinely different terrain. Mango lies east of Alba in the Langhe Bianco zone, where Chardonnay and Moscato ripen in different conditions from the Nebbiolo communes. Costigliole d'Asti, further east into the Asti hills, is the source for Moscato d'Asti DOCG. Dogliani, south of La Morra in the Langa Monregalese, grows Dolcetto at altitude in its own appellation. Each site determines which grape goes into which bottle; the range follows the geography rather than being forced onto a single estate.

Soil And Site

The La Morra vineyards at Marcenasco sit on the calcareous-clay soils characteristic of the commune, contributing to the fuller texture and approachable fruit profile of Ratti's Barolo. Serradenari, a more recently delineated La Morra site at higher altitude, provides different conditions within the same commune, producing a Barolo with a distinct character from Marcenasco. The six estates include varied soil types across the portfolio: from the clay-heavy Barolo communes to the lighter soils of the Asti hills. All vineyards are managed under integrated and sustainable production regimes.

Story

Renato Ratti came back to Italy in 1965 with a clear idea of what Barolo could be. The prevailing practice in the zone was to blend Nebbiolo across communes, which flattened geographical differences into a generic appellation character. He bought at Marcenasco and made his first wine from that single site, then spent years building the cartographic and intellectual case that the Barolo zone's parcels were worth naming and separating on a label.

The work was not only viticultural. Ratti wrote about Barolo's subzones, argued in print and in conversation that place mattered within the appellation, and produced the map that gave growers and merchants a shared language for discussing origin. He was specific about what he was doing: recognising individual subzones and classifying vintages were both principles he wrote into the estate's stated philosophy, and bottle ageing was treated not as a luxury but as a necessary tool for softening Nebbiolo's tannin without sacrificing the wine's ability to develop.

When Pietro took over in 1988 after Renato's death, he kept those principles intact. He did not modernise the philosophy or break from the subzone approach. Serradenari, the estate's second Barolo cru, debuted with the 2019 vintage and reached the market in 2023, the newest extension of the founding argument that distinct La Morra sites deserve separate labels.

Vineyards And Cellar

The Marcenasco vineyard in La Morra is Ratti's founding parcel and the source for the estate's anchor Barolo. Serradenari comes from a higher-altitude La Morra site that produces a Barolo with different fruit weight and lift. Barbera d'Alba and Dolcetto d'Alba are drawn from La Morra vineyards. Brigata, the Langhe Chardonnay, comes from Mango. Moscato d'Asti from Costigliole d'Asti and Dogliani Dolcetto from the southernmost estate complete the range.

Integrated and sustainable farming governs all six sites. The cellar at Frazione Annunziata was rebuilt in 2005, the new construction designed to follow the hill's profile so that the building recedes into the slope rather than projecting above it. Ratti's stated cellar philosophy treats bottle ageing as central: wines are held before release to allow Nebbiolo's tannin to settle and the wine's parts to knit, preserving smoothness and the capacity to develop over time.

Wines

Two Barolo DOCG wines anchor the range. Marcenasco is made entirely from Nebbiolo grown at the founding La Morra site, producing a Barolo with the fuller, rounder profile typical of calcareous-clay ground: dried rose petals and tar on the nose, red cherry and tobacco on the palate, with firm tannin that softens after several years in bottle. Serradenari comes from a higher La Morra site and shows a more vertical, floral character, with tighter fruit and bright acidity. The 2019 vintage was the first; the wine reached the market in 2023.

Barbera d'Alba DOC from La Morra delivers high natural acidity, deep colour, and dark cherry fruit without oak dominance. Dolcetto d'Alba DOC, also from La Morra, is softer, with bitter almond on the finish that is characteristic of the grape. Brigata, the Langhe Chardonnay DOC from Mango, is fermented and refined on lees for freshness and a clean mineral line, with the capacity for modest bottle development. Moscato d'Asti DOCG from Costigliole d'Asti is low in alcohol, sweet, lightly sparkling, and intensely aromatic, built around Moscato Bianco's apricot and orange blossom character. Dogliani DOCG from the southernmost estate adds a second Dolcetto, grown at altitude in that separate appellation and showing a darker, earthier profile than the La Morra version.

In The Glass

Marcenasco Barolo opens with dried roses and tar, the classic Nebbiolo aromatic signature, followed by red cherry, tobacco leaf, and dried herbs on the palate. The tannin is firm and granular from young Nebbiolo, but La Morra's calcareous clay softens the edge relative to Serralunga or Castiglione Falletto, and bottle age draws the parts together into a rounder, more complete wine. The acidity is high and persistent, running through the palate and keeping the finish long and dry. Serradenari shows more lift and floral character, with citrus and red fruit over tighter tannin, reflecting the higher altitude of that site. Across both Barolos, the finish is dry, firm, and mineral, with the depth that allows ten to fifteen years of further development on good vintages.

Brigata Chardonnay is lighter in texture, with white peach and lemon, a clean acid line, and a lightly creamy mid-palate from lees contact. Barbera d'Alba is richer in colour and fruit, high in acidity, and built for the table rather than the cellar. Moscato d'Asti is delicate and sweet, with low alcohol and persistent floral and stone-fruit perfume.

A Bottle To Understand It

Barolo DOCG Marcenasco is the founding wine and the clearest way into this estate. It is 100 percent Nebbiolo from the La Morra parcel that Renato Ratti bought in 1965, the same site that prompted the whole cartographic argument about Barolo's subzones. In the glass it gives dried roses, tar, and red cherry, with firm but not brutal tannin, high acidity that runs through to a long dry finish, and the mineral depth that develops with time. La Morra's calcareous clay makes it more approachable in youth than Barolos from the sandstone communes, which means it does not need decades of patience to drink well, though it has the constitution to age. Start here to understand what Ratti built and why La Morra produces the Barolo it does.

Anecdote

When Renato Ratti returned to the Langhe in 1965, he found a wine zone that had no public map of its own. Barolo's growers knew their parcels by name and memory, but the subzones had never been drawn, labelled, and printed for anyone outside the valley to read. Ratti sat down and made one. He divided the Barolo zone into its constituent localities, named each one, noted soil types and characters, and published the result as a physical document. It was not an official act, a regulatory submission, or a commercial proposal; it was a cartographer's argument that place mattered and deserved to be visible. The Menzione Geografica Aggiuntiva system that legally recognises vineyard names on Barolo labels came into being decades later, but the map Ratti drew gave the conversation its first shared language. Every bottle of Barolo that carries a vineyard name on its label is, in a small way, still working from that document.

Final Word

Ratti is the La Morra estate that made the subzone argument before anyone else formalised it. Marcenasco remains the founding wine: Nebbiolo from calcareous-clay ground, held in bottle before release, rounder and more approachable in youth than Barolos from the harder-soiled communes but built with enough acidity and tannin to develop over a decade or more. The range is wider than two Barolos suggest, spanning five appellations and four communes, each wine reflecting genuinely different soil and climate. Pietro Ratti has continued from where his father left off: the same approach to subzones, the same bottle ageing philosophy, and now a second Barolo cru to add to the estate's argument about La Morra.
