Asti DOCG

Gancia's own history traces Italian sparkling wine to Carlo Gancia, born in 1829 in Narzole, who went to Reims in 1848 to learn the méthode champenoise at Piper Heidsieck. In 1850 he founded Fratelli Gancia & C. in Chivasso with his brother Edoardo, and Gancia dates to 1865 the wine it calls the first Italian spumante, made from Piedmontese Moscato and first sold as 'Moscato Champagne' or 'Champagne Italiano'. On 11 May 1866 the brothers moved the business to Canelli. Decanter's James Button (2021) credits Federico Martinotti, from the province of Asti, with inventing the tank method for controlled fermentation in large vats in 1895, and notes that Eugène Charmat developed the autoclave design fifteen years later. According to Gancia, Camillo Gancia led the founding of the Consorzio dell'Asti in 1932 to guarantee the origin and quality of Moscato. The DOC was recognised by presidential decree of 9 July 1967 and the DOCG by ministerial decree of 29 November 1993, as the 2026 MASAF disciplinare records. Decanter (2021) notes that the wine officially called Asti Spumante until 1993 is now officially just 'Asti', and that modifications in 2017 and 2020 removed the old 9.5% alcohol ceiling, so Asti can now be fermented to dryness. Italian Wine Central records that the Canelli subzone became a separate DOCG in 2023 and that rosato versions were added in 2026.

• Gancia (per its own history): Carlo Gancia trained in Reims from 1848, founded Fratelli Gancia & C. in Chivasso in 1850, dates the first Italian spumante to 1865, and moved to Canelli on 11 May 1866
• Federico Martinotti invented the tank method in 1895; Eugène Charmat developed the autoclave design fifteen years later (Decanter, 2021)
• DOC 9 July 1967; DOCG 29 November 1993 (2026 MASAF disciplinare); the 2017 and 2020 modifications allowed Asti to be fermented to dryness (Decanter, 2021)

Article 3 of the 2026 MASAF disciplinare delimits the zone by whole municipalities: nine in the province of Alessandria (among them Acqui Terme and Strevi), 28 in the province of Asti (among them Canelli, Calosso and Nizza Monferrato) and 13 in the province of Cuneo (among them Santo Stefano Belbo, Castiglione Tinella and Serralunga d'Alba), plus the frazioni of Como and San Rocco Senodelvio in the comune of Alba. Article 9 of the disciplinare dates the formation of the soils to more than 12 million years ago, when the retreating sea left what is now the Po Valley. The oldest land lies in the centre and west, on the Cassinasco formation of the Serravallian (13 to 11 million years ago), with sandstone and permeable sandy-loam soils; the younger east, formed 10 to 5 million years ago, sits on the Marne di Sant'Agata with visible gypsum veins and compact, water-retentive silty-loam soils. The same article places the vineyard hills between 150 and 600 metres, with 45% of vineyards between 200 and 300 metres, 30% between 300 and 400 metres and 17% above 400 metres, facing mainly south in the west and south-east or south-west in the east. It describes a continental climate that pushed growers onto the steepest slopes: of more than 10,000 hectares registered, 25% have gradients above 30%, 10% above 40% and 4% above 50%. Article 4 admits only hillside vineyards of favourable aspect, preferably calcareous or calcareous-clay, and excludes valley-floor or flat, light or damp sites.

• Zone (Article 3): 9 Alessandria, 28 Asti and 13 Cuneo municipalities in full, plus two frazioni of Alba; Article 9 counts 51 municipalities
• Altitude (Article 9): hills between 150 and 600 m; 45% of vineyards at 200 to 300 m, 30% at 300 to 400 m, 17% above 400 m
• Soils (Article 9): older sandstone and sandy-loam in the centre and west; younger Marne di Sant'Agata with gypsum veins and silty-loam in the east
• Slopes (Article 9): of more than 10,000 ha registered, 25% exceed a 30% gradient; Article 4 excludes valley-floor and flat sites

Article 2 of the 2026 MASAF disciplinare requires at least 97% Moscato Bianco, with the remaining 3% from aromatic white varieties suited to Piedmont; Decanter's James Button (2021) adds that in practice most Asti wines are single-varietal, and identifies Moscato Bianco as Muscat Blanc à Petits Grains. Button writes that, among wines made by the Martinotti-Charmat method, Asti is unique in that the must is fermented only once: it absorbs some carbon dioxide during fermentation in pressurised autoclaves, the autoclave is chilled to stop fermentation at the desired alcohol level, and the wine is filtered to remove the yeast before bottling. Under Article 5 of the disciplinare, the autoclave process for Asti cannot last less than one month including bottle ageing, and Article 7 lets producers print 'metodo Martinotti' on the label. Asti Metodo Classico must be made by natural fermentation in bottle, with at least nine months in the same winery, uninterrupted on the lees, before disgorgement. The disciplinare caps grape yield at 10 t/ha and the grape-to-wine yield at 75%, requires at least 4,000 vines per hectare for new plantings, and allows refrigeration to spread fermentations across the year. Winemaking must take place in the provinces of Alessandria, Asti and Cuneo or in Pessione, a frazione of Chieri, while bottling must take place within the delimited zone. Gancia's own technical sheet for its Asti DOCG describes soft pressing with the must split into three fractions, of which only the first is used, cold storage of the must until the presa di spuma (the sparkling fermentation), the Martinotti method, 7.5% vol and 89 g/l of residual sugar.

• Grapes (Article 2): at least 97% Moscato Bianco; up to 3% other aromatic white varieties suited to Piedmont
• Martinotti method: a single fermentation in pressurised autoclaves, stopped by chilling, then filtered (Decanter, 2021); at least one month in process (Article 5)
• Asti Metodo Classico (Article 5): natural fermentation in bottle, at least nine months on the lees, then disgorgement
• Yields (Articles 4 and 5): 10 t/ha of grapes; 75% grape-to-wine; new plantings at least 4,000 vines/ha

Gancia, founded in 1850 and based in Canelli since 1866, still lists an Asti DOCG made by the Martinotti method, and its history page says the company returned fully to Italian capital control in 2025. Martini & Rossi was co-founded in 1863, with the herbalist Luigi Rossi among its founders, and its Martini Asti DOCG is made from Moscato Bianco; Decanter's James Button (2021) called Martini 'The most famous Asti brand' and credited this to marketing, particularly in the 1980s. Fontanafredda, in Serralunga d'Alba, dates itself to 1858 and reports 120 hectares of organic crops, and its Asti was among the wines in Button's 2021 Decanter tasting. In Castiglione Tinella, the Saracco family has made Moscato since the early 1900s; it sold wine to Asti Spumante producers between 1950 and 1988, when Paolo Saracco began bottling Moscato d'Asti under his own label, and the family works 50 hectares.

• Gancia: founded 1850 in Chivasso; in Canelli since 1866; lists an Asti DOCG made by the Martinotti method (per Gancia)
• Martini & Rossi: co-founded 1863; Martini Asti DOCG from Moscato Bianco (per Martini); 'The most famous Asti brand' (Decanter, 2021)
• Paolo Saracco: Castiglione Tinella; own-label bottling since 1988 from 50 hectares (per Saracco)

Article 1 of the 2026 MASAF disciplinare lists the types of the Asti DOCG: Asti (or Asti Spumante), Asti Metodo Classico, rosato or rosé versions of both, Moscato d'Asti and Moscato d'Asti Vendemmia Tardiva, with the subzones Santa Vittoria d'Alba and Strevi governed by annexes. At release, Asti must show a fine, persistent mousse, at least 11.50% vol total alcohol of which at least 6.00% vol actual, and at least 4.5 g/l total acidity, in styles from pas dosé to dolce; Asti Metodo Classico needs at least 12.00% vol total alcohol, with at least 6.00% vol actual, and 6.0 g/l acidity. The rosato types blend 70% to 90% Moscato Bianco with 10% to 30% Brachetto, with Brachetto yields capped at 8 t/ha. Moscato d'Asti, made in the same zone from the same grape, must have between 4.50% and 6.50% vol actual alcohol, at least 11.00% vol total, and an overpressure no higher than 2.5 bar; the mushroom cork and wire cage are banned for it. Vintage labelling is compulsory for every type except the sparkling ones, and sugar-level terms may not share a line with the denomination. Italian Wine Central (2023) reports that the Canelli DOCG, which it counts as Piedmont's 19th and Italy's 77th, makes only sweet frizzante wines from 100% Moscato Bianco, adds a Riserva level aged at least 30 months including 20 in bottle, and remains under the Asti consorzio. Decanter (2021) cited the Consorzio dell'Asti as saying that 85% of Asti production is exported, with Germany, Russia and the US among key markets.

• Asti (Article 6): at least 11.50% vol total, 6.00% vol actual; 4.5 g/l acidity; pas dosé to dolce
• Moscato d'Asti (Article 6): 4.50% to 6.50% vol actual; at least 11.00% vol total; no more than 2.5 bar
• Rosato (Article 2): 70% to 90% Moscato Bianco with 10% to 30% Brachetto; Canelli DOCG Riserva: at least 30 months, 20 in bottle (Italian Wine Central, 2023)
