Castello di Monsanto

The story

The First Harvest, 1962

In the autumn of 1962, Fabrizio Bianchi had owned the Monsanto estate for less than a year. The property had come to him as a wedding gift, and the first harvest was already underway. When the fruit from Il Poggio came in, Bianchi set it aside from the rest of the estate's grapes and vinified it alone, in its own vessel, from its own single slope. When it came time to bottle, he put the vineyard name on the label. No Chianti Classico producer had done this before. The appellation had always merged parcels, smoothed the blend, sent the wine out under the regional name. Bianchi's label named a place within the place, a hill within the zone, and committed to it in the very first year. The bottles from that harvest still sit in the estate archive beneath the castello, the oldest evidence that the decision was made and held.

At A Glance

The Producer

Fabrizio Bianchi received the Monsanto property as a wedding gift from his parents in 1962. Most wine families take a generation to find their direction. Bianchi found his in the first harvest.

That autumn, he separated the grapes from one parcel, the Il Poggio vineyard, and vinified them apart from the rest of the estate's fruit. He then put the vineyard name on the label. No producer in Chianti Classico had done this before. The wine that came from that decision is now the estate's flagship, and the archive holds bottles from every vintage since.

Fabrizio still manages the estate today alongside his daughter Laura. The 206-hectare property sits in the San Donato in Poggio subzone, in the southern reaches of Chianti Classico. Seventy-two hectares carry vines across four named parcels: Il Poggio, Scanni, Il Mulino, and Il Salcio. The rest is woodland and fifteen hectares of olive orchards.

Place

Chianti Classico is the historic core of Chianti, a Sangiovese appellation in the Tuscan hills between Florence and Siena. San Donato in Poggio is one of its recognized subzones, sitting toward the appellation's southern boundary where the landscape opens and the altitude keeps temperatures in check.

Monsanto's vineyards run from 280 to 320 metres above sea level. At that elevation, Sangiovese ripens steadily across most years without losing acidity. The appellation label on a bottle of Chianti Classico signals Sangiovese as the dominant grape; a Riserva designation on top means extended ageing before release. A single-vineyard name, like Il Poggio, means the grapes come from one identified parcel only.

Mistral winds blow in directly from the Tyrrhenian Sea. They improve grape health and create temperature fluctuation.

Soil And Site

Galestro covers most of the estate. It is a schistous rock that breaks into gravelly surface layers, and vine roots push down through those layers to find moisture and minerals in the harder rock beneath. The galestro at Monsanto is associated with firm tannin extraction and bright acidity in the finished wines.

On the southern slope, galestro alternates with tuff, a looser volcanic soil that drains more freely. The two soil types sit within the same estate but produce slightly different conditions for ripeness and extraction, which is part of why Il Mulino, the tuff-influenced parcel, was chosen for the estate's Cabernet Sauvignon planting rather than the Sangiovese blocks.

Story

When Fabrizio Bianchi founded Castello di Monsanto in 1962, single-vineyard bottling was not part of how Chianti Classico worked. Producers blended across their estate, or sold to négociants who blended further. The appellation name carried the wine; the source parcel was invisible on the label.

Bianchi's decision to name Il Poggio changed the terms of what a Chianti Classico could be. It established that a single parcel within the appellation could carry its own vineyard name on the label and be bottled separately. The bottles archived at the estate from 1962 onward are the physical record of that argument.

In 1981, the estate took a further step. Bianchi planted Cabernet Sauvignon in the Il Mulino vineyard and in that year made the first harvest for what would become Nemo, a 100 percent Cabernet Sauvignon bottling at a time when such a wine was unusual in the Chianti Classico landscape. Where Il Poggio had pushed Sangiovese toward specificity, Nemo pushed the estate toward variety, and confirmed that Monsanto's four named vineyards were being treated as distinct growing environments rather than interchangeable sources.

Laura Bianchi joined her father in managing the estate and has continued the same approach: four named parcels feeding a range that runs from the estate Riserva to the single-vineyard wines.

Vineyards And Cellar

The four vineyards, Il Poggio, Scanni, Il Mulino, and Il Salcio, are farmed as separate blocks rather than as a single pooled source. Il Poggio carries Sangiovese only and feeds the flagship Riserva. Il Mulino holds the Cabernet Sauvignon for Nemo. The Riserva blends Sangiovese with Canaiolo and Colorino.

Fermentation for the Riserva takes place in temperature-controlled, truncated-conical steel vats. Délestage and pump-overs work the cap over 18 to 20 days, extracting colour and tannin from the Sangiovese skins at a controlled pace. The cellar beneath the estate runs 300 metres and holds more than 1,300 barriques, giving the wines room to age before they leave the property.

Wines

The range has three distinct tiers.

The Castello di Monsanto Chianti Classico Riserva is the estate-level wine. Sangiovese leads, with Canaiolo and Colorino as blending partners. After fermentation in steel, the wine goes into barrel for the ageing period required by the Riserva classification. It is an accessible example of the estate's wines: Sangiovese-driven, with cherry fruit, herbal notes, and the firm tannin that galestro soils tend to produce.

Il Poggio is the single-vineyard Chianti Classico Riserva. Sangiovese only, from the parcel Bianchi separated in 1962. It spends more time in barrel and in bottle before release, and the fruit concentration from one identified slope gives it more depth and a longer finish than the estate Riserva. Tannin is firm and fine-grained, acidity stays high, and the wine needs time in bottle to open.

Nemo is 100 percent Cabernet Sauvignon from Il Mulino, first made in 1981. It sits outside the Chianti Classico appellation rules and is bottled under a different classification. Nemo has darker fruit, fuller body, and more obvious oak character.

In The Glass

The estate Riserva opens with dried cherry, red plum, a brush of tobacco leaf, and the faintly earthy note that galestro Sangiovese often carries. The mid-palate is firm rather than plush, with Sangiovese tannin that grips without hardening, and an acid line that keeps the fruit from going soft. Canaiolo and Colorino soften the edges slightly without changing the fundamental character. The finish is dry, with a hint of oak spice and lingering cherry skin.

Il Poggio at a few years past release shows more concentration: the cherry deepens toward dried fruit and iron, the tannin is finer but more present, and the acidity lifts everything through a long, mineral finish. It is a wine that rewards patience. Open it too young and the tannin dominates; give it a decade and it finds a balance that the estate-level wine rarely reaches.

A Bottle To Understand It

Start with the Castello di Monsanto Chianti Classico Riserva. It is a Sangiovese-led blend with Canaiolo and Colorino, aged in barrel before release. The fruit is clear and defined, cherry and dried herb, the tannin is firm but not aggressive, and the acidity keeps the wine lively from first pour to last sip. It gives a direct read on what galestro Sangiovese from San Donato in Poggio tastes like before the extra concentration and ageing time of Il Poggio push the wine into more demanding territory. Once that foundation makes sense, Il Poggio is the next step.

Anecdote

In the autumn of 1962, Fabrizio Bianchi had owned the Monsanto estate for less than a year. The property had come to him as a wedding gift, and the first harvest was already underway. When the fruit from Il Poggio came in, Bianchi set it aside from the rest of the estate's grapes and vinified it alone, in its own vessel, from its own single slope. When it came time to bottle, he put the vineyard name on the label. No Chianti Classico producer had done this before. The appellation had always merged parcels, smoothed the blend, sent the wine out under the regional name. Bianchi's label named a place within the place, a hill within the zone, and committed to it in the very first year. The bottles from that harvest still sit in the estate archive beneath the castello, the oldest evidence that the decision was made and held.

Final Word

Castello di Monsanto made one move in 1962 that changed what a Chianti Classico label could say. Il Poggio named its source parcel when no one else was doing it, and the estate has been accountable to that vineyard ever since. The Riserva is the clearest way in: Sangiovese on galestro, aged properly, priced to reach. Il Poggio is where the argument gets serious.
