Tenuta di Bibbiano

Tenuta di Bibbiano makes Sangiovese-only Chianti Classico from two named slopes in Castellina, on the western edge of the appellation. The estate has been in the same family since 1865 and certified organic across all 37 hectares of vineyard. Concrete vats replace oak as the primary ageing vessel, keeping Sangiovese's fruit and acidity direct.

The producer

Tenuta di Bibbiano has made one commitment and held it for more than five decades: pure Sangiovese, aged in concrete rather than oak, from certified-organic vineyards on the western edge of Chianti Classico. Brothers Tommaso and Federico Marrocchesi Marzi run the estate today as the fifth generation of the family that acquired the property in March 1865. The consulting oenologist Giulio Gambelli first came to Bibbiano in November 1942, trained under Tancredi Biondi-Santi, and guided the estate toward unblended Sangiovese at a time when most Chianti producers were diluting the grape with white varieties or adding Cabernet Sauvignon for international appeal. Bibbiano released its first estate-label wine from the 1969 harvest and has not blended another variety into its Chianti Classico since.

The vineyards occupy two named slopes within the Castellina UGA: Capannino, facing southwest on clay and limestone-schistose rock, and Montornello, facing northeast. Both are certified organic. Fermentation runs in stainless steel; ageing uses concrete vats across the entire range, a choice that keeps oak tannin and vanilla out of the wine and Sangiovese's natural acidity and sour cherry fruit at the centre. The range runs from an Annata sourced across both slopes to a Riserva with extended concrete ageing and a Gran Selezione Vigna del Capannino from the single named southwest slope. Total production is approximately 150,000 bottles.

Notable facts

The story

The Student Who Stayed

In November 1942, Pier Tommaso Marzi brought Giulio Gambelli to Bibbiano. Gambelli was still a student, trained under Tancredi Biondi-Santi, and the invitation was not framed as the beginning of anything long. It lasted roughly six decades. During those years, when Chianti producers were routinely blending white grapes into the wine to lighten it, or adding Cabernet Sauvignon to give it weight that would travel, Gambelli kept pushing Bibbiano in the opposite direction: Sangiovese, alone, farmed and made without amendment. When the estate released its first estate-label wine from the 1969 harvest, the bottle carried no second variety and no oak ageing. That wine's successors are still made the same way.

The Producer

Tenuta di Bibbiano has made one commitment and held it for more than five decades: pure Sangiovese, aged in concrete rather than oak, from certified-organic vineyards on the western edge of Chianti Classico. The estate is in the municipality of Castellina in Chianti and is run by brothers Tommaso and Federico Marrocchesi Marzi, the fifth generation of the family that acquired the property in March 1865.

The commitment to unblended Sangiovese is not an accident of tradition. It traces to November 1942, when Pier Tommaso Marzi invited consulting oenologist Giulio Gambelli to the estate. Gambelli, then a young student of Tancredi Biondi-Santi, guided Bibbiano toward pure-variety Sangiovese at a time when most Chianti producers were diluting the grape with white varieties or blending in international grapes to soften it. That direction held. Bibbiano released its first estate-label wine from the 1969 harvest and has not blended another variety into its Chianti Classico since.

Place

Castellina in Chianti sits on the western boundary of the Chianti Classico zone, farther from the cooling influence of the Arno valley than the central communes of Gaiole or Radda. The position brings altitude variation, a drier growing season, and Sangiovese that tends toward fuller body and riper tannin than wines from the eastern flank of the appellation. Bibbiano falls within the Castellina UGA. Every bottle from Bibbiano carries the Chianti Classico DOCG designation; the single-vineyard Gran Selezione adds the Castellina UGA alongside the vineyard name.

Soil And Site

The estate's vineyards occupy two named slopes with different aspects and different soils. Capannino faces southwest, with clay and limestone-schistose rock. Montornello faces northeast. The contrast in exposure means the two slopes ripen Sangiovese at different rates and produce fruit with different tannin texture and aromatic weight. Southwest-facing Capannino accumulates more heat through the growing season, giving the grapes from that slope the concentration and structural depth that justify the Gran Selezione bottling. Northeast-facing Montornello ripens more slowly, contributing freshness and aromatic lift. Both slope names appear on the Bibbiano range as functional wine divisions, not only as marketing geography.

Story

A parchment deed of 1089 records the estate, castle, church, farms, and vineyards of Bibbiano under the name "castello de Bibiune." The current family's formal connection begins in March 1865, when brothers Casimiro and Pietro Marzi acquired the property.

Five generations of continuous ownership is not, by itself, what defines the estate. The defining moment came in 1942, when the family brought Giulio Gambelli to Bibbiano and began an oenological relationship that lasted roughly six decades. Bibbiano's Chianti Classico is made only from Sangiovese. Bibbiano adopted that argument and built its first estate-label release around it in 1969.

By the late 1980s the estate had already moved toward low-impact vineyard inputs and organic fertilisers, decades before organic viticulture became commercially fashionable in Chianti Classico. All vineyard hectares are now certified organic. Photovoltaic panels supply more than 70% of the estate's energy, a commitment that runs alongside the farming philosophy rather than supplementing it.

Vineyards And Cellar

Published figures for the planted vineyard area range from about 30 to 37 hectares, all certified organic and dominated by Sangiovese. The Chianti Classico consortium also records Sangiovese Grosso, Malvasia Nera, Colorino, Trebbiano, and Malvasia del Chianti among varieties planted on the estate, though none of these appear in the Annata, Riserva, or Gran Selezione. The estate Chianti Classico is sourced across both slopes, drawing from Capannino and Montornello rather than from a single parcel.

Fermentation takes place in stainless steel. Ageing uses concrete vats as the primary vessel. The choice is deliberate: concrete does not add oak tannin or vanilla, does not introduce extraction, and keeps Sangiovese's fruit character and natural acidity at the centre of the wine. The 2021 Annata spent 16 days on skins in stainless steel, then 12 months in cement. The Riserva follows the same approach with extended ageing. The Gran Selezione Vigna del Capannino uses the same vessels for a single-vineyard wine that demands longer time rather than different material.

Wines

Bibbiano makes three tiers of Chianti Classico, all from 100% Sangiovese and all using concrete as the majority ageing vessel.

The Chianti Classico Annata draws from both the Capannino and Montornello slopes. It is the estate's broadest wine and the most direct expression of Sangiovese from the Castellina position: medium-bodied, with sour cherry, redcurrant and strawberry on the nose, bright acidity from the concrete ageing, and a tannin frame that is present but not heavy. There is no oak character to compete with the fruit.

The Chianti Classico Riserva extends the time in concrete and produces a wine with more concentration and firmer tannin than the Annata, but the absence of new wood keeps the savory, iron-edged quality of Sangiovese intact rather than sweetening it.

The Chianti Classico Gran Selezione Vigna del Capannino is a single-vineyard wine from the southwest-facing slope. Clay and limestone-schistose soils, more heat accumulation, and the inherent selection of Gran Selezione regulations combine to produce the deepest concentration in the range. It has more structural weight than the Riserva, darker fruit, and the ageing capacity to develop over a decade or more.

Total production across all three tiers is approximately 150,000 bottles.

In The Glass

Sangiovese grown in Castellina and aged in concrete has a particular signature. The nose leads with sour cherry, redcurrant, and fresh strawberry, sometimes a trace of dried herbs or iron. In the mouth the acidity arrives early and stays through the finish, not as sharpness but as the line that keeps the wine from feeling flat. Tannins on the Annata are medium-grained and integrated; on the Riserva they tighten and lengthen, needing food or time. On the Gran Selezione Vigna del Capannino, the tannin frame is the most pronounced of the three and the fruit the most concentrated, with darker cherry and plum alongside the iron-mineral quality that the limestone-schistose soils of Capannino contribute.

The concrete ageing does a specific job across the range: it rounds the wine without softening it, and it keeps Sangiovese's acidity bright without amplifying it into austerity. There is no vanilla, no toasted wood, no oak-derived sweetness anywhere in the range.

A Bottle To Understand It

Start with the Chianti Classico Annata. It draws from both Capannino and Montornello, 100% Sangiovese, 12 months in concrete, no oak. The wine gives sour cherry and redcurrant from the glass, a firm but open tannin frame in the mouth, and a finish that stays clean and fruit-forward rather than drying out. It sits at medium body. The acidity is the structural element you notice most, keeping the wine lively rather than heavy. No other Bibbiano wine exposes the house's core approach more plainly: one grape, one appellation, one vessel, no blending. Drink it with food that can take acidity and tannin, which is most of the Italian table.

Anecdote

In November 1942, Pier Tommaso Marzi brought Giulio Gambelli to Bibbiano. Gambelli was still a student, trained under Tancredi Biondi-Santi, and the invitation was not framed as the beginning of anything long. It lasted roughly six decades. During those years, when Chianti producers were routinely blending white grapes into the wine to lighten it, or adding Cabernet Sauvignon to give it weight that would travel, Gambelli kept pushing Bibbiano in the opposite direction: Sangiovese, alone, farmed and made without amendment. When the estate released its first estate-label wine from the 1969 harvest, the bottle carried no second variety and no oak ageing. That wine's successors are still made the same way.

Final Word

Bibbiano is a Castellina estate that settled its argument in 1969 and has not reopened it. Sangiovese only, concrete only, organic across every hectare. The range runs from a fresh, accessible Annata through a structured Riserva to a single-vineyard Gran Selezione from the southwest-facing Capannino slope. There is nothing decorative about the approach. The wines are built to carry Sangiovese's natural acidity and savory character without oak overlay, and they do.
