Vernaccia di San Gimignano DOCG

The disciplinare records Vernaccia in the Commune of San Gimignano's levy regulations (ordinamenti delle gabelle) of 1276, which imposed a tax of three soldi on each soma of Vernaccia sold outside the communal territory. It also relays, while calling the origin uncertain, the account that a certain Vieri de' Bardi brought the vine from Liguria around 1200, and an alternative derivation of the name from the Latin vernaculum. In the Divine Comedy, Dante sends Pope Martin IV to Purgatory to expiate the sin of gluttony for the eels of Bolsena drowned in Vernaccia (Purgatorio, Canto XXIV), and the Consorzio says Vernaccia is the only wine Dante mentions. The Consorzio's timeline also lists a 1565 panel by Giorgio Vasari in Palazzo Vecchio representing San Gimignano and Colle Val d'Elsa with a young satyr drinking Vernaccia, and Ignazio Malenotti lamenting in 1815 that no San Gimignano vineyard was still planted with Vernaccia alone. The disciplinare says the wine almost disappeared from the record after the medieval and Renaissance period until after the Second World War, when San Gimignano's growers rediscovered the variety and went on to obtain DOC status in 1966.

• DOC: presidential decree of 3 March 1966 (GU 110, 6 May 1966); DOCG: ministerial decree of 9 July 1993 (GU 169, 21 July 1993), per the MASAF disciplinare
• 1276: the Commune's levy regulations tax Vernaccia sold outside San Gimignano (MASAF disciplinare; Consorzio timeline)
• Dante Alighieri names Vernaccia in Purgatorio, Canto XXIV; the Consorzio calls it the only wine mentioned in the Divine Comedy
• Consorzio della Vernaccia di San Gimignano established on 3 July 1972 (Consorzio history page)

The disciplinare places the whole production territory within the municipality of San Gimignano, in the north-west of Siena province, halfway between the Tyrrhenian coast and the Apennine ridge. It describes a hilly territory between 67 and 629 m above sea level, with vineyards between 70 and 500 m; the Consorzio's terroir page gives the municipality's range as 64 to 631 m over 138 km². Soils are of Pliocene origin, 6.8 to 1.8 million years old: marine deposits of yellow sand (tufo) and yellow and grey clays, often stratified over more compact clays at depth, which the Consorzio's terroir page calls blue. The Consorzio credits the widespread tufa and cavernous limestone substrates with the savoury touch of the area's wines. The disciplinare calls the climate sub-Mediterranean, with rather dry summers, rather cold winters, average annual rainfall of around 700 mm over 83 rainy days, good ventilation all year and rare fog.

• Pliocene marine soils of yellow sand (tufo) and yellow and grey clays over more compact clays (MASAF disciplinare)
• Vineyards lie between 70 and 500 m, and 500 m is the legal ceiling (MASAF disciplinare)
• Rainfall: around 700 mm a year over 83 rainy days per the disciplinare; 600 to 700 mm over about 70 days per the Consorzio's terroir page
• Susan Hulme MW (Decanter, 2021) describes south-facing hillsides of mainly yellow sand (tufa) rich in fossils and seashells, and northern hillsides with more clay
• Consorzio vice president and agronomist Nadia Betti told Decanter (2024) that no zoning has ever been done, though four zones giving different wine styles can be identified

The disciplinare reports that a study by Sergè-genomics, a University of Siena spin-off commissioned by the Consorzio, found substantial genetic uniformity among San Gimignano's productive Vernaccia vines, matching the variety held in the official reference collections. It adds that a derivation of the name from the Latin vernaculum would explain its use for entirely different vines, such as those of Oristano and Serrapetrona. The wine must contain at least 85% Vernaccia di San Gimignano. Article 6 describes a straw-yellow colour with golden highlights that deepen with age, a delicate, fine nose of initial fruity notes that can evolve toward mineral notes with ageing, and a dry, harmonious, sapid palate, sometimes with a characteristic almond aftertaste. Susan Hulme MW (Decanter, 2021) writes that the variety has relatively low acidity, is low in aromas and high in tannins, and that the wines come in two main styles: unoaked, lees-aged whites with citrus, grapefruit and mineral notes, and richer oaked versions with spice, chestnut and warm honey notes. For the Riserva, the Consorzio lists honey, white and black pepper, saltiness, moss, chalk, sugared almonds and mineral notes of flint.

• The name is also used for unrelated vines of Oristano and Serrapetrona, per the disciplinare's account of the Latin vernaculum
• At least 85% Vernaccia di San Gimignano; the Consorzio describes a range from 85% up to 100%
• Minimum total alcohol 11.50% vol (Riserva 12.50% vol); residual sugar up to 4.0 g/l; minimum total acidity 4.5 g/l; minimum non-reducing extract 16.0 g/l (MASAF disciplinare)
• Wooden vessels are permitted for vinification and storage (MASAF disciplinare), and the Consorzio says each producer chooses the container type for Riserva ageing

The Consorzio was established on 3 July 1972. Its history page says it obtained the DOCG in 1993 and in 2012 became an erga omnes consortium acting for all producers of the appellations, members or not, at a time when it represented more than 40% of producers and more than 65% of the wine produced. Since 1996 it has also protected San Gimignano DOC wines. Its overview page states that in 2022 it had 80 member producers, representing 88% of the area's vineyards, 64 of whom released wine under their own labels. The Consorzio's figures record 147 companies claiming the denomination in the 2025 harvest, 81 of them members. Its producer list includes Panizzi, Teruzzi, Montenidoli, Il Colombaio di Santa Chiara, Cappellasantandrea and Guicciardini Strozzi. Decanter (2024) quoted Irina Guicciardini Strozzi as president of the consorzio and Walter Sovran as director at Panizzi, and noted that the late Giovanni Panizzi was consorzio president from 2003 to 2009.

• Consorzio founded 3 July 1972; erga omnes since 2012 (Consorzio history page)
• 2022: 80 member producers covering 88% of the area's vineyards, 64 of them releasing wine under their own labels (Consorzio overview page)
• Area: about 750 ha dedicated to Vernaccia di San Gimignano DOCG out of roughly 2,000 ha of vines in the municipality, per the undated Consorzio terroir page (fetched 2026); Italian Wine Central gives 580 ha for 2021
• The Consorzio's harvest table lists 4,283,923 bottles for 2025 and 5,157,174 for 2013; Decanter (2024) reported production steady for decades at about five million bottles, with the vineyard register closed in 1998

The disciplinare, last amended by ministerial decree of 15 October 2024, reserves the DOCG for white wine, including a Riserva type. Grapes must come from hillside vineyards in the municipality of San Gimignano, and vinification, ageing and bottling must take place there, apart from wineries holding a ministerial authorisation under the rules approved on 9 July 1993 and individual bottling authorisations under Law 238/2016. Maximum grape yield is 9 tonnes per hectare and maximum grape-to-wine yield 70%; an excess of up to 5% loses the DOCG, and above 75% the whole lot loses it. New plantings need at least 4,000 vines per hectare, forcing is banned, emergency irrigation is allowed and the tendone training system is prohibited. Minimum natural alcohol of the grapes is 10.50% vol, or 12.00% vol for Riserva. The Consorzio says its 2010 amendments were the first production regulations for an Italian wine to explicitly exclude certain grape varieties.

• Riserva: at least 11 months from 1 January after the harvest, then three months in bottle before release; Riserva grapes are declared separately each year
• Labels must state the vintage and the geographic term Toscana; the vigna mention is allowed with its place name
• Bottles must be Bordeaux-shaped glass, from 0.187 to 3 litres
• Control body: Valoritalia (MASAF disciplinare)
