Barone Ricasoli
Eight hundred and eighty-five years. One castle.
A castle on the historical border between Florence and Siena. The Ricasoli family arrives in 1141 — and never leaves. Through eight centuries of war, plague, Renaissance, unification, and revolution, the family endures. In 1872, Bettino Ricasoli — the Iron Baron, 2nd Prime Minister of unified Italy — writes a letter that defines the Chianti formula. One hundred and twenty-four years later, the modern DOCG codifies what he had anticipated.
The Castle · the Iron Baron · the Letter
In 1141, written testimony attests that the Ricasoli family already possesses Castello di Brolio, twenty kilometres north of Siena, in the Chianti hills above Gaiole. From this date forward, the family will hold the castle without interruption for 885 years and counting. Through Florentine-Sienese border wars, Renaissance fortifications by Giuliano Sangallo in 1484, Spanish invasions, the Risorgimento, and even World War II artillery — Brolio endures. In 1809, in the very same castle, is born Bettino Ricasoli — the Iron Baron, 2nd Prime Minister of unified Italy. He inherits a family estate heavily in debt at age eighteen. He spends three decades experimenting with every grape variety. And on 26 September 1872, he writes a letter to Professor Cesare Studiati of the University of Pisa that defines, for the first time in history, the Chianti formula. Sangiovese for vigour and aroma. Canaiolo for sweetness. Malvasia for everyday drinking. A century and twenty-four years later, in 1996, the modern Chianti Classico DOCG codifies what the Iron Baron had anticipated.
Eight hundred and eighty-five years. One castle. One letter that defined a wine.
A Tuscan fortress between two warring republics. Renaissance walls in 1484. Wine exports to Amsterdam and England by the late 1600s. Five centuries of unbroken Ricasoli tenure before the Iron Baron is born.
The Ricasolis at Castello di Brolio · the 885-year unbroken chain begins
Year 1141. The Ricasoli family is already in possession of Castello di Brolio — twenty kilometres north of Siena, on a hill above Gaiole in Chianti. Written testimony from that year is the first document that ties the name Ricasoli to the castle. Eight hundred and eighty-five years later, that same family will still hold those same walls. It is one of the longest unbroken family chains in the history of European wine.
Brolio in the border wars · destruction and revival
For four centuries, Castello di Brolio stands on the border between the Republic of Florence and the Republic of Siena. It is sacked, burned, rebuilt — sacked, burned, rebuilt again. The Ricasolis never sell. They never leave. Every time the castle falls, the family raises it from its own stones. By the end of the Quattrocento, the walls have been demolished and rebuilt so many times that the very stones carry the memory of survival.
Giuliano Sangallo rebuilds the walls · the Renaissance fortification
1484. Giuliano da Sangallo — one of the great architects of the late-fifteenth-century Tuscan Renaissance — rebuilds the outer walls of Castello di Brolio. The same Sangallo who works for Lorenzo de' Medici, who designs villas for the Florentine ruling families. The Ricasolis are no longer a feudal house living among rural fortifications: they are clients of the same architect who serves the Medici. The Renaissance walls Sangallo raises in 1484 still stand today.
The first international wine exports · Amsterdam and England
Late seventeenth century. The wines of Brolio cross the Alps — Amsterdam, England. Documents of the period confirm the first international shipments. The Brolio wine is not a local production; it is a commercial export, traded on the great European markets of the era. Three and a half centuries before any modern brand of Chianti, the wines of Brolio already had a name beyond Italy.
A child orphaned at eighteen. A debt-laden estate. Three decades of grape experimentation. And the rise of one of the principal political figures of the Italian Risorgimento.
Bettino Ricasoli is born
9 March 1809. Bettino Ricasoli is born in Florence, into the Ricasoli noble family. He will live seventy-one years, seven months, and fourteen days. He will die at the same Castello di Brolio where his ancestors have lived for six and a half centuries. In those seventy-one years, he will become twice Prime Minister of Italy — and invent the formula for Chianti.
Orphaned at eighteen · the debt and the responsibility
1827. Bettino is eighteen years old. His father dies. The Ricasoli estate is buried in debt. By special decree of the Grand Duke of Tuscany, the young man is declared of age before his time and entrusted with the guardianship of his younger brothers and the family lands. He retreats to Brolio. From that moment, the castle is no longer a noble residence — it is a project to be saved.
The thirty-year experiment · every grape variety at Brolio
Castello di Brolio, 1840. Bettino Ricasoli begins to plant every grape variety he can lay his hands on. French Cabernet. Pinot. Riesling. Native Tuscan Sangioveto. Canaiolo. Malvasia. Trebbiano. For thirty years he will keep planting and keep comparing — vintage after vintage, parcel after parcel, in the same cellars at Brolio. He calls it «my experiment». It is the longest single comparative vineyard study in nineteenth-century Italian wine.
The political life · La Patria, Gonfaloniere, twice Prime Minister of Italy
In parallel with the vineyards, Bettino enters politics. In 1847 he founds the journal La Patria. He becomes Gonfaloniere of Florence. After the unification of Italy in 1861, he is twice Prime Minister of Italy — once in 1861, again in 1866. In the years he leads the new Italian state, he is at the same time conducting his thirty-year vineyard experiment at Brolio. The history calls him «the Iron Baron» — Barone di Ferro — for the discipline with which he holds together both lives at once.
A four-year three-grape experiment. A satisfied Iron Baron. A letter to a professor in Pisa. And the document that defines Chianti for the next century and a half.
The decisive experiment · Sangioveto, Canaiolo, Malvasia
Castello di Brolio, 1867. After twenty-seven years of comparative trials, Bettino declares the experiment complete. Of the dozens of varieties tested across the Brolio hillsides, three have proved themselves: Sangioveto (the Tuscan native — backbone, structure, longevity), Canaiolo (softening, accessibility), and Malvasia (perfume, freshness, for younger drinking). The Iron Baron has his formula.
The Letter · the Chianti formula is born
26 September 1872. Bettino Ricasoli writes a letter to Professor Cesare Studiati of the University of Pisa. In that letter — preserved and published decades later — he sets down his formula in writing for the first time: Sangioveto for the backbone and aroma, Canaiolo for softness, Malvasia for the young wines. The letter of 26 September 1872 is the founding act of modern Chianti. One hundred and twenty-four years later, the official DOCG regulation will codify almost exactly what Bettino wrote that day.
Bettino dies at Brolio · the Iron Baron's last act
23 October 1880. Bettino Ricasoli dies at Castello di Brolio. Seventy-one years old. He dies in the same fortress where his Ricasoli ancestors have lived for seven hundred and thirty-nine years. Twice Prime Minister of a country that did not exist when he was born. Inventor of the formula that will define Chianti for centuries. The Iron Baron returns to the walls his family has held since 1141 — and never leaves.
A multinational mismanagement era. The family takes the winery back. The DOCG codifies what Bettino anticipated. And Francesco Ricasoli — the 32nd Baron — leads the renewal.
The multinational era · the family decides to take it back
1980s into the early 1990s. Brolio operations pass into multinational ownership. In the family's own subsequent description, the period «risked driving the estate into commercial mediocrity». For the first time in eight and a half centuries, the wine of Brolio was being managed by hands that were not Ricasoli hands. The family watches. And decides to take it back.
Francesco Ricasoli · the 32nd Baron · the renewal begins
1993. Francesco Ricasoli — the 32nd Baron — takes over management of the company. The 32nd-Baron designation is itself the record of an unbroken succession: thirty-two generations of Ricasolis at Brolio. Francesco invests in vineyard restoration, on parcel-by-parcel selection, on the return to the Sangiovese-led discipline of the Iron Baron. The Ricasolis take back what was theirs for eight centuries.
The DOCG codifies what Bettino had anticipated · 124 years later
1996. The Chianti Classico DOCG regulation is established. It codifies what Bettino Ricasoli had anticipated in his letter of 26 September 1872: Sangiovese as the backbone of the blend. One hundred and twenty-four years separate the Iron Baron's letter from the official law of the Italian Republic. The state finally codifies what the Baron had written in his own hand.
