Malvasia di Casorzo d'Asti DOC

The Malvasia grape family takes its name from Monemvasia, an ancient fortified port in the Greek Peloponnese, and arrived in Italy via Venetian trade routes during the medieval period. The first documented mention of Malvasia vineyards in the Monferrato area dates to 1468, in Mondonio. The modern wine industry in Casorzo was consolidated when more than 200 farmers joined forces in 1951 to establish Cantina di Casorzo, conducting their first harvest in 1954 amid widespread rural depopulation. The appellation obtained formal DOC recognition in 1968, formalizing production standards for this distinctive regional style.

The production zone straddles the border between Asti and Alessandria provinces, just northeast of Asti town and southwest of Casale Monferrato. Despite the DOC carrying the 'Asti' name, two-thirds of the communes covered are within Alessandria province. The seven permitted communes are Casorzo, Grana, and Grazzano Badoglio in Asti province, and Altavilla Monferrato, Olivola, Ottiglio, and Vignale Monferrato in Alessandria province. Only hillside vineyards are eligible, predominantly on calcareous clay soils with favorable exposure; vineyards on valley floors and flatlands are expressly excluded. The area is characterized as adequately ventilated and luminous, conditions the discipline considers essential to optimal vine development.

• Zone covers approximately 53 hectares across seven communes in Asti and Alessandria provinces
• Two-thirds of the DOC's communes lie within Alessandria province, not Asti, despite the appellation name
• Only hillside vineyards on calcareous clay soils with correct aspect are permitted; flatlands are excluded
• Production zone straddles the inter-provincial border between Asti town and Casale Monferrato

Malvasia di Casorzo (Malvasia Nera) must comprise at least 90 percent of the blend, with the remaining 10 percent optionally coming from Freisa, Grignolino, Barbera, or other local aromatic grapes. The appellation produces three recognized styles. The base Rosso is a lightly sparkling, medium-sweet red with a minimum actual alcohol of 4.5%. The Spumante is a fully sparkling style made similarly to Moscato d'Asti: very fruity, sweet, and low in alcohol, at a minimum of 6.5% actual. The Passito, the most concentrated expression, requires grapes dried on the vine to reach a minimum potential alcohol of 15%, though this level is rarely if ever achieved in practice; it carries a minimum residual sugar of 50 g/l. Color ranges from cerasuolo pink to ruby red depending on style. The grape's closest Piedmontese counterpart is Malvasia di Castelnuovo Don Bosco, grown northwest of Asti.

• Minimum 90% Malvasia Nera (di Casorzo); maximum 10% Freisa, Grignolino, Barbera, or other aromatic Piedmont varieties
• Alcohol minima by style: 4.5% Rosso (10.5% potential), 6.5% Spumante (11.0% potential), 10.0% Passito (15.0% potential)
• Passito grapes must be dried on the vine; minimum residual sugar 50 g/l; the 15% potential alcohol threshold is rarely achieved
• Wine color varies from cerasuolo pink to ruby red; Spumante style is made in a similar method to Moscato d'Asti

Cantina di Casorzo, officially Cantina Sociale di Casorzo S.A.C., is by far the dominant producer, accounting for approximately 95% of total Malvasia di Casorzo DOC output. Founded in 1951 and located in the valley between Casorzo and Grana, the cooperative manages around 200 hectares of vineyards across 12 denominations of origin, producing approximately 15,000 hectoliters annually from around 20,000 quintals of grapes. Total bottled output reaches around 450,000 bottles in 22 different wine types. Two notable independent producers also craft the wine: Azienda Agricola Accornero, based in Vignale Monferrato, produces the 'Brigantino' bottling, a 100% Malvasia Nera wine widely available on export markets. Tenuta Montemagno produces 'Dulcem', a sweet sparkling expression made from south-facing hillside vineyards.

Casorzo remains a quiet corner of Piedmont with minimal commercial wine tourism infrastructure compared to better-known neighboring zones such as Asti or Alba. Cantina di Casorzo, located in the valley between Casorzo and Grana, offers tastings and guided cellar tours amid the Piedmontese countryside, and is the most accessible point of entry for visitors. The estate of Azienda Agricola Accornero in Vignale Monferrato offers Grand CRU Vineyard Tours including guided cellar visits and tastings. The Cantina is also noted for its proximity to the 'Bialbero di Casorzo', a cherry tree growing atop a mulberry tree counted among the 100 most unusual trees in the world. Traditional Piedmontese cuisine in the area includes tajarin pasta, vitello tonnato, and bagna cauda, all natural companions to the local Malvasia.
