Chianti DOCG

Documents in the Datini archive (1383-1410) in Prato use the term Chianti for the first time to designate a special type of wine, and notarial documents from 1398 describe Chianti as a white wine. In September 1716 a Bando issued under Grand Duke Cosimo III de' Medici regulated the Chianti, Carmignano, Pomino and Valdarno di Sopra zones and penalised counterfeiting. The Chianti Classico consortium holds that the original Chianti zone defined in 1716 is today's Chianti Classico territory. Baron Bettino Ricasoli, working with his Castello di Brolio wines, set out a blend led by Sangioveto with Canaiolo and Malvasia in a letter to Professor Cesare Studiati of the University of Pisa; the 2026 disciplinare dates the letter to 1870, while both the Consorzio Vino Chianti and the Chianti Classico consortium date it to 1872. The Consorzio Vino Chianti was founded in 1927, a ministerial decree of 31 July 1932 delimited the Chianti area for the first time as seven production zones, and Chianti became a DOC in 1967 and a DOCG in 1984. The Superiore category was added in 1996, Montespertoli became the seventh subzone in 1997, and the ministerial decree of 5 June 2026 added Chianti Rosé and the Terre di Vinci subzone.

• 1716: the September Bando under Cosimo III de' Medici regulated Chianti, Carmignano, Pomino and Valdarno di Sopra wines
• 1927 and 1932: the Consorzio Vino Chianti is founded, and the ministerial decree of 31 July 1932 delimits the Chianti area for the first time
• 1967 and 1984: DOC by presidential decree of 9 August 1967, DOCG by presidential decree of 2 July 1984
• 1996, 1997 and 2026: Chianti Classico becomes an autonomous DOCG by decree of 5 August 1996; Montespertoli is delimited by ministerial decree of 8 September 1997; the 5 June 2026 decree adds Rosé and Terre di Vinci

The Chianti DOCG is spread across six provinces: Florence, Siena, Arezzo, Pisa, Pistoia and Prato. The zone lies in central Tuscany on hill country near the Apennines, and only hillside vineyards with suitable aspect and orientation qualify. The territory divides geologically into four systems, from oldest to youngest: Mio-Eocene pre-Apennine ridges, Pliocene hills, the Valdarno Superiore intermountain basin with its Pleistocene deposits, and alluvial deposits. Vineyard hills average between 200 and 400 m above sea level, and the climate is continental, from humid to sub-humid, with a water deficit in summer. Average annual rainfall is 867 mm, peaking in November at 121 mm and lowest in July at 32 mm, with August the warmest month at average temperatures above 23°C and January the coldest at around 5°C.

• Elevation: vineyard hills average between 200 and 400 m above sea level
• Geology: four systems, from Mio-Eocene pre-Apennine ridges to alluvial deposits
• Climate: humid to sub-humid with a summer water deficit; average annual rainfall 867 mm
• Rufina: limestone, marl and alberese soils, with south to southwest facing slopes up to 400 m above sea level

Sangiovese is the principal grape: red Chianti may contain from 60 to 100%, with other varieties suitable for cultivation in Tuscany making up the balance. White grapes may not exceed 10%, and Cabernet Franc and Cabernet Sauvignon together may not exceed 15%, or 10% in the Colli Senesi subzone. Sangiovese is a medium-late-ripening variety, usually harvested from the second half of September to mid-October. Canaiolo is used to convey smoothness to Chianti, and Colorino was used extensively in Chianti blends in the past. The traditional governo all'uso Toscano, a slow refermentation of newly racked wine with lightly dried grapes, is permitted for red Chianti but not for the Rosé. The Rosé type needs at least 60% Sangiovese, with the rest drawn from a list of fifteen named varieties that includes Canaiolo, Colorino, Malvasia Bianca Lunga, Trebbiano Toscano and Vernaccia di San Gimignano.

• Sangiovese: 60 to 100% in red Chianti under the 2026 disciplinare; the previous text required at least 70%
• Canaiolo and Colorino: both on the list of complementary varieties; Canaiolo conveys smoothness
• Cabernet Franc and Cabernet Sauvignon: no more than 15% together, or 10% in Colli Senesi
• White grapes: no more than 10% in red Chianti; Trebbiano Toscano and Malvasia Bianca Lunga both belong to the historic Chianti blend

Wine labelled with a subzone must be made from grapes grown and vinified within that subzone's delimited territory. Until 2026 the disciplinare named seven subzones: Colli Aretini, Colli Fiorentini, Colli Senesi, Colline Pisane, Montalbano, Montespertoli and Rufina. The disciplinare approved on 5 June 2026 adds Terre di Vinci, whose delimitation begins in the Comune di Lamporecchio. Rufina, which its consortium calls the highest Chianti, lies about 20 km from Florence in the districts of Pontassieve, Rufina, Londa, Pelago and Dicomano. New Rufina vineyards need a minimum planting density of 4,500 vines per hectare, against 4,100 elsewhere. Montespertoli's delimitation dates from a ministerial decree of 8 September 1997.

• Rufina: 12,483 hectares of surface area, 750 of them registered under vines
• Colli Senesi: Cabernet Franc and Cabernet Sauvignon capped at 10%, and a 13.00% minimum alcohol for Riserva
• Montespertoli: delimited by ministerial decree of 8 September 1997, the seventh subzone
• Terre di Vinci: added by the decree of 5 June 2026, with a maximum grape yield of 9 t/ha and release from 1 September after the harvest

The 2026 disciplinare provides for Chianti with or without a subzone, Chianti Riserva with or without a subzone, Chianti Rosé with or without a subzone, and Chianti Superiore. Basic Chianti may be released from 1 March after the harvest, with a maximum grape yield of 11 t/ha and a minimum total alcohol of 11.50% vol. Subzone wines need a minimum of 12.00% vol and have later release dates for Colli Fiorentini and Montespertoli (1 June) and for Rufina and Terre di Vinci (1 September). Superiore has a maximum yield of 9.5 t/ha, a minimum of 12.50% vol and release from 1 September after the harvest. Riserva requires at least two years of ageing from 1 January after the harvest and a minimum of 12.50% vol, or 13.00% vol for Colli Senesi Riserva, while Rosé may be released from 1 December of the harvest year. Chianti Classico is a separate DOCG: vineyards in the oldest zone, governed by its own separate regulation, cannot be planted or registered for Chianti.

• Chianti: release from 1 March after the harvest, minimum 11.50% vol, maximum 11 t/ha
• Chianti Superiore: release from 1 September after the harvest, minimum 12.50% vol, maximum 9.5 t/ha
• Chianti Riserva: at least two years of ageing from 1 January after the harvest, minimum 12.50% vol, or 13.00% vol for Colli Senesi
• Chianti Classico: an autonomous DOCG since the decree of 5 August 1996; white grapes were banned from its blend from the 2006 vintage, and Gran Selezione was introduced in 2013

Rufina sits in the Sieve valley north-east of Florence, running from Pontassieve to Dicomano, and its consortium keeps a directory of member producers. Castello Nipozzano, an ancient stronghold defending Florence from the year 1000, is a Frescobaldi family property, and Fattoria Selvapiana began in the Middle Ages as a watchtower on the Sieve valley before it became a villa. The region's ancient wine cellars have become architectural heritage to visit, and the grape harvest normally starts in early September and continues in stages according to area and altitude.

• Castello Nipozzano (Rufina): a Frescobaldi estate listed in the Chianti Rufina producer directory
• Fattoria Selvapiana (Rufina): a medieval watchtower turned villa, also in the Rufina producer directory
• Rufina towns: Pontassieve, Rufina, Londa, Pelago and Dicomano
• Harvest: normally from early September, in stages by area and altitude
