Vernaccia di San Gimignano DOCG

Vernaccia appears 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. One account has a certain Vieri de' Bardi bringing the vine from Liguria around 1200, though the origin is uncertain, and another derives 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 calls Vernaccia the only wine Dante mentions. In 1565 Giorgio Vasari painted a panel in Palazzo Vecchio representing San Gimignano and Colle Val d'Elsa with a young satyr drinking Vernaccia, and in 1815 Ignazio Malenotti lamented that no San Gimignano vineyard was still planted with Vernaccia alone. After its medieval and Renaissance fortune the wine almost disappeared from the record 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)
• 1276: the Commune's levy regulations tax Vernaccia sold outside San Gimignano
• Dante Alighieri names Vernaccia in Purgatorio, Canto XXIV
• Consorzio della Vernaccia di San Gimignano established on 3 July 1972

The whole production territory lies within the municipality of San Gimignano, in the north-west of Siena province, halfway between the Tyrrhenian coast and the Apennine ridge. The municipality covers 138 km² of hilly territory between 67 and 629 m above sea level, with vineyards between 70 and 500 m. 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 blue clays at depth. The widespread tufa and cavernous limestone substrates give the area's wines their characteristic savoury touch. The climate is 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
• Vineyards lie between 70 and 500 m, and 500 m is the legal ceiling
• Rainfall: around 700 mm a year over 83 rainy days, lowest in summer and peaking in autumn
• South-facing hillsides are mainly yellow sand (tufa) rich in fossils and seashells; the northern hillsides carry more clay
• No zoning has ever been done, though in 2024 Consorzio vice president and agronomist Nadia Betti identified four zones

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. 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. Its colour is straw yellow with golden highlights that deepen with age; the nose is delicate and fine, with initial fruity notes, which can evolve toward mineral notes with ageing; the palate is dry, harmonious and sapid, sometimes with a characteristic almond aftertaste. Writing in Decanter in 2021, Susan Hulme MW found the variety relatively low in acidity and aromas and high in tannins. The wines broadly 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. Riserva can add 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, which a Latin vernaculum origin would explain
• At least 85% Vernaccia di San Gimignano, so blends 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
• Wooden vessels are permitted for vinification and storage, and each producer chooses the container type for Riserva ageing

The Consorzio was established on 3 July 1972. 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. In 2022 it had 80 member producers, representing 88% of the area's vineyards, 64 of whom released wine under their own labels. In the 2025 harvest 147 companies claimed the denomination, 81 of them members. The Consorzio's producer list includes Panizzi, Teruzzi, Montenidoli, Il Colombaio di Santa Chiara, Cappellasantandrea and Guicciardini Strozzi. In 2024 Irina Guicciardini Strozzi was president of the consorzio and Walter Sovran director at Panizzi; the late Giovanni Panizzi was consorzio president from 2003 to 2009.

• Consorzio founded 3 July 1972; erga omnes since 2012
• 2022: 80 member producers covering 88% of the area's vineyards, 64 of them releasing wine under their own labels
• Area: about 750 ha dedicated to Vernaccia di San Gimignano DOCG out of roughly 2,000 ha of vines in the municipality
• Bottles: 4,283,923 for the 2025 harvest and 5,157,174 for 2013; by 2024 production had held 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 2010 amendments made these 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
