The Producer
Terreno is a Chianti Classico estate that sits immediately outside Greve in Chianti, with vineyards spread across the Greve and Montefioralle communal zones in the DOCG's northern reaches. The Swedish Ruhne family has owned it since 1988. Sofia Ruhne runs it now, and the arc of how she got there is more deliberate than most succession stories.
She made her first wine at Terreno in 2010 while still living elsewhere, moved to the property full-time in 2011, spent the next three years guiding the organic transition with her father, and formally took over in 2015. Tuscany-based oenologist Giacomo Fioravanti, who spent more than a decade at Isole e Olena before joining Terreno, advises the cellar. The combination of a driven young director and a technically grounded oenologist from one of Chianti Classico's more methodical estates gives Terreno a clear working philosophy: farm well, intervene as little as possible, and let vintage conditions dictate vessel choice.
The estate covers 150 hectares, of which 20 are vineyards, 10 are olive groves, and the bulk is forest. All wine comes from Terreno's own parcels. Nothing is bought in.
Place
Greve in Chianti is one of the DOCG's principal towns and the commercial heart of the northern zone. As a UGA, Greve covers substantial altitude variation and a range of exposures, typically producing Sangiovese with firm tannin and lively acidity, shaped by its galestro and alberese soils. Galestro is a friable, schistose rock that drains quickly and limits vine vigour; alberese is a harder, calcium-rich clay-limestone that opens slowly and pushes ripeness later into the season.
Montefioralle is a small medieval hilltop commune a few kilometres from Greve town, elevated above the valley floor, with clay-rich and volcanic soils that tend toward more concentrated fruit and a darker, fuller mid-palate in the wine. As a UGA it is compact and little-planted relative to the broader DOCG, which means individual parcel character matters more.
Terreno's vineyards span both zones. That split translates directly into how the range is built: the entry Chianti Classico draws on both UGAs together, while the upper tiers are tied to individual parcels.
Soil And Site
The Greve parcels sit on the galestro and alberese soils typical of the northern Chianti Classico hillsides. Galestro breaks down into thin, nutrient-poor layers that limit canopy growth and concentrate flavour in the grape. Alberese holds moisture longer, moderates drought stress, and adds a stony, mineral backbone to the wine.
Montefioralle's soils carry a stronger volcanic and clay component. The clay retains water through dry summers and contributes to deeper colour and fuller fruit weight in the Sangiovese. Together, the two soil types give Terreno raw material that runs from tight, acidic, and long to richer and rounder, depending on which parcels dominate a given cuvée.
Story
The Ruhne family came to Chianti Classico from Sweden in 1988 and made their first harvest the following year. For more than two decades Terreno operated as a family property without a clear second generation in place. That changed when Sofia Ruhne, then in her early twenties, chose to engage with the estate as a winemaker rather than an inheritor.
The organic certification arrived in 2014, the result of several years of transition work that Sofia undertook alongside her father. Converting 20 hectares to certified organic in Chianti Classico, where summer heat and humidity create persistent pressure from mildew and other vineyard diseases, requires sustained commitment to copper and sulphur treatments, green cover crops, and seasonal vigilance that synthetic inputs would otherwise simplify. The certification is not decorative. It reflects a set of decisions made across multiple vintages under real agronomic pressure.
By 2022, Sofia had been elected president of the Vintners' Association of Montefioralle, a recognition that places her inside the civic life of one of Chianti Classico's smallest and most historically significant communes.
Vineyards And Cellar
Harvesting at Terreno is done entirely by hand. After the initial pick, grapes go through a second manual sorting at the cellar to remove anything underripe or damaged before fermentation begins. The effect is visible in the wine: only grapes at a uniform ripeness level enter each tank.
Fermentation is spontaneous across the range. No commercial yeast is added; native yeast populations from the vineyard and cellar carry each ferment. This increases vintage variation but also links the wine more directly to the soil and season it came from.
Vessel choice is not fixed. The cellar uses oak barrels, clay amphorae, concrete tanks, and ceramic containers, and the decision is made vintage by vintage. A cooler, tighter vintage might spend time in oak to add weight; a richer vintage might go into clay or concrete to preserve freshness. The only additive across all wines is a small amount of sulphur, added to protect the wine during élevage and bottling.
Wines
Terreno builds its range in three tiers, each anchored to a distinct geographic and ageing logic within the Chianti Classico DOCG.
Le Tre Vigne (Chianti Classico DOCG) is the estate's main wine and takes its name from the three vineyard plots that supply it. Sangiovese leads the blend, with Canaiolo and Colorino alongside; the wine draws on parcels in both the Greve and Montefioralle UGAs. On the palate, Le Tre Vigne shows the dark cherry and dried herb character typical of northern Chianti Classico Sangiovese, with firm but supple tannin, medium body, and the kind of bright acidity that keeps the wine fresh through a long meal. Versatile enough to open young and capable of several years in bottle.
Le Bonille di Sopra (Chianti Classico Riserva) is a single-vineyard wine aged longer than the base tier. The Le Bonille di Sopra parcel sits in Montefioralle territory; the wine includes Sangiovese with Canaiolo and Colorino. The extended élevage deepens the mid-palate and broadens the tannin, moving from the livelier profile of Le Tre Vigne toward something more serious and food-dependent. Darker fruit, more earth, a longer finish.
Sillano (Chianti Classico Gran Selezione) comes from the single Sillano parcel, the top of the range. Gran Selezione requires a minimum of 30 months of ageing including at least three months in bottle before release, and producers typically reserve their most site-specific fruit for it. The 2020 Sillano is a Sangiovese from a single vineyard at high altitude, matured for 18 months in large oak casks and at least one year in bottle.
In The Glass
Across the range, Terreno Sangiovese runs on the firmer, more acidic side of Chianti Classico. The spontaneous fermentations and second hand-sorting produce wines with clear, defined fruit rather than opulent or jammy character. Cherry, dried rose petal, wild herb, and iron-edged earth come up from the glass. In the mouth, the acidity arrives early and drives through the mid-palate, framing whatever fruit weight is there. Tannin is present in all three wines but integrated, finishing with grip rather than dryness.
Le Tre Vigne keeps things compact and immediate: a wine where the acidity and tannin are matched, neither dominating. Le Bonille di Sopra opens that frame, with more depth on the mid-palate and a finish that lingers on dried herb and dark plum. Sillano pushes the same qualities further, adding a mineral quality and a finish that stays longer than the others.
The vessel variation across vintages means there is no single oak signature. Some years carry a light vanilla note from barrel ageing; others show no oak character at all. What stays constant is the acidity line and the clarity of the Sangiovese fruit.
A Bottle To Understand It
Start with Le Tre Vigne. It is a Chianti Classico DOCG from Sangiovese grown across Terreno's Greve and Montefioralle parcels, and it carries the full range of what the estate is doing in a bottle priced for regular drinking rather than occasion. Bright acidity, dark cherry, firm tannin that softens with an hour of air or a plate of food. Nothing here is obscured by heavy oak or pushed to overripe sweetness. Le Tre Vigne is Terreno at its most direct: organic fruit, spontaneous fermentation, minimal intervention, and the northern Chianti Classico character intact in the glass.
Anecdote
Sofia Ruhne made her first wine at Terreno in 2010 without yet living there. She drove to the estate for the harvest, worked the vintage, and drove back. The following year she moved in. Over the next three years she worked alongside her father to convert the vineyards to certified organic, a process that meant replacing synthetic treatments with copper and sulphur, establishing green cover crops between the rows, and managing the elevated mildew risk that comes with Chianti Classico's humid summers. The organic certification came through in 2014. In 2015, she formally took over as director. Seven years after that first harvest, she was elected president of the Vintners' Association of Montefioralle, the small hilltop commune whose parcels run alongside Terreno's own vines. The first vintage she made there, she was a visitor. The association presidency she carried home.
Final Word
Terreno is a Chianti Classico estate that chose a slower, more demanding route through a period when easier options were available. Organic certification, spontaneous fermentation, and hand-sorted harvests all require more labour and accept more vintage risk than conventional alternatives. The wines reflect those choices in the glass: defined, acidic, unadorned Sangiovese from a northern Chianti Classico address, made by a director who built her role over five years rather than inheriting it overnight.
