Summary

Tenuta San Guido in Bolgheri is the estate behind Sassicaia – and therefore behind one of the most influential wines of modern times. What began in the 1940s as a private experiment by Marchese Mario Incisa della Rocchetta became, with the 1968 vintage, the first commercially sold Sassicaia and ultimately the forefather of the Super Tuscans: a Tuscan red from Cabernet Sauvignon and Cabernet Franc that deliberately looked to Bordeaux. To this day the Incisa della Rocchetta family farms around 100 hectares of vines on an estate of roughly 2,500 hectares between the coastal hills and the sea – and holds, in the Bolgheri Sassicaia DOC, an appellation that exists only once in Italy.

History

The story begins with Marchese Mario Incisa della Rocchetta (1899–1983), who moved to the Maremma in the early 1940s. He was convinced that the stony, gravelly soils of his land resembled those of the Bordeaux appellation of Graves – and that a great red wine in the French mould was possible here. In 1944 he planted just over a hectare of Cabernet Sauvignon on higher ground near Castiglioncello di Bolgheri.

From 1945 to 1967 the wine remained a private affair, bottled only for family and friends. It was the 1968 vintage that finally reached the market – from 1971 – and Italian critics immediately recognised it as something exceptional. Two people were decisive in the leap from enthusiast's project to global name: Nicolò Incisa della Rocchetta (born 1936), the founder's son, who turned the estate into a modern family business and took charge of its commercial launch, and the legendary oenologist Giacomo Tachis, who gave the wine its form and accompanied it for decades. His last vintage was 2007; since 2009/2010 the oenologist Graziana Grassini – a protégée of Tachis – has been responsible for the cellar. Today Nicolò Incisa is honorary president; the third generation, five cousins of the family, is growing into its responsibilities, and Priscilla Incisa della Rocchetta represents the house externally.

Location & Terroir

Tenuta San Guido lies near Bolgheri, a hamlet of Castagneto Carducci on the Tuscan coast. The property extends for around 13 kilometres from the slopes of the coastal range down to the Tyrrhenian Sea – a gradient of altitude and climate typical of Bolgheri that gives the estate access to very different parcels.

The soils gave the wine its name: sassi means stones, and stones are exactly the point. The vineyards sit on gravelly, stony, free-draining soils, in places with limestone and clay content, at elevations from a few metres up to around 400 metres. Soils like these force the vines to root deeply, keep yields naturally low and give the wines their fine, taut structure. Then there is the maritime influence: the sea breeze keeps the grapes healthy and cools the hot summer nights, while the shelter of the hills behind protects the vines from weather extremes. It is precisely this combination that allows Cabernet to be picked fully ripe and yet elegant in Tuscany.

Style & Philosophy

The estate's style is remarkably consistent and restrained. Sassicaia does not chase maximum power but finesse, perfume and fidelity to its origin – leaner in build than many of its rivals, with fine-grained tannins, notes of cedar and herbs, and an upright freshness that can carry the wine for decades. Ageing is traditionally in French oak, without the wood ever dominating. The signature remains French-inspired, but the result is unmistakably Tuscan.

Behind it lies a philosophy of long lines: no frequent changes of course, no fashions, simply the refinement of an ideal once found. All three wines of the house share the genetic fingerprint of Cabernet – they differ in ambition and accessibility, not in the underlying idea. It is also worth noting that wine is only part of the whole: the estate is home to a famous thoroughbred stud (Razza Dormello Olgiata) and to the Padule di Bolgheri wildlife refuge, a protected area affiliated with the WWF – a commitment to landscape and biodiversity older than the wine's commercial success.

Notable Vineyards & Wines

The range is deliberately small and clearly tiered:

  • Sassicaia – the grand vin from Cabernet Sauvignon and Cabernet Franc, bottled as Bolgheri Sassicaia DOC; a wine of exceptional ageing potential
  • Guidalberto – since the 2000 vintage, a blend of Merlot and Cabernet Sauvignon, juicier and ready to drink earlier
  • Le Difese – since 2002, Cabernet Sauvignon with Sangiovese, the most Tuscan and most approachable wine of the house

The key vineyards lie around Castiglioncello di Bolgheri on the higher sites as well as on the plain towards the coast. Unlike in Burgundy or on the Mosel, individual parcels are not marketed as single-vineyard wines – the origin is the DOC itself.

Its own Bolgheri Sassicaia DOC

When Bolgheri became a DOC in 1994, Sassicaia had long since been a category of its own. The wine was therefore granted its own subzone within the new appellation, covering exclusively the vineyards of Tenuta San Guido. In 2013 that subzone was elevated to the fully independent Bolgheri Sassicaia DOC. That makes it a one-off in Italian wine law: the only denominazione reserved for a single wine from a single producer.

Awards

The estate's reputation was sealed internationally in 1992, when Robert Parker awarded the 1985 vintage a perfect 100 points – the first ever 100-point score for an Italian wine. Scarcely less powerful was the naming of Sassicaia 2015 as Wine Spectator's Wine of the Year in 2018, exactly 50 years after the first commercial vintage. Before and since, Sassicaia has regularly collected top scores from the international wine press.

More important than individual scores, however, is the impact: without Tenuta San Guido, Bolgheri as a wine region would not exist in its present form – and the Super Tuscans, which re-established Italy's standing in the wine world, would have had no model to follow.

Frequently asked questions

What is Tenuta San Guido known for?

Tenuta San Guido in Bolgheri is the estate behind Sassicaia – the wine that changed Italy's standing in the wine world. From the 1940s onwards it produced a red wine modelled on Bordeaux, made from Cabernet Sauvignon and Cabernet Franc, which went on sale with the 1968 vintage and triggered the Super Tuscan movement. The estate is also regarded as the pioneer of the entire Bolgheri wine region.

What is the difference between Sassicaia, Guidalberto and Le Difese?

Sassicaia is the grand vin: a blend of Cabernet Sauvignon and Cabernet Franc in its own Bolgheri Sassicaia DOC, built for decades of ageing. Guidalberto (first vintage 2000) combines Cabernet Sauvignon with Merlot and drinks well much earlier. Le Difese (from 2002) pairs Cabernet Sauvignon with Sangiovese and is the most affordable way into the estate's signature.

Where is Tenuta San Guido located?

The estate lies in Bolgheri, a hamlet of Castagneto Carducci in the province of Livorno on the Tuscan coast. The property runs for around 13 kilometres from the slopes of the coastal range down to the Tyrrhenian Sea – which shapes the climate, the soils and the style of the wines alike.

Why does Sassicaia have its own DOC?

Because the wine was already a benchmark in its own right by the time Bolgheri was elevated to DOC status in 1994: Sassicaia was granted its own subzone within the Bolgheri DOC. In 2013 that subzone became the independent Bolgheri Sassicaia DOC. It is the only Italian appellation reserved for a single wine from a single producer.
