Erbaluce di Caluso DOCG

Erbaluce di Caluso DOCG sits in the Canavese subregion of Piedmont, centered on the town of Caluso and spanning 33 municipalities in the province of Turin, roughly 35-40 km north of the city. The vineyards occupy a natural moraine amphitheater formed by glacial deposits during the ice ages, with elevations ranging from 250 to 410 meters above sea level. This glacial legacy defines the soils: sandy-gravel substrates rich in quartz, granite, and mineral sands, delivering the mineral tension that characterizes the wines.

• 33 municipalities in Turin province make up the production zone
• Elevations of 250-410 meters above sea level
• Soils are glacial moraine with granitic, sandy-gravel character
• Natural wind protection in the amphitheater reduces fungal disease pressure

The Canavese enjoys a cool Alpine climate, with sheltered vineyard positions providing natural protection from wind and the fungal diseases that moisture can encourage. Marked day-to-night temperature fluctuations are a defining feature, preserving the high natural acidity in Erbaluce grapes that makes the variety so versatile across wine styles.

• Cool Alpine climate with significant diurnal temperature variation
• Sheltered amphitheater position offers natural wind and disease protection
• Cool nights preserve Erbaluce's characteristically high acidity

Erbaluce is a native Piedmontese variety thought to originate in the Alpine foothills of northern Piedmont. Its name likely derives from the Italian words 'erba' (herb or grass) and 'luce' (light), though local legend connects it to the mythical goddess Albaluce. The grape's defining trait is its high acidity, which allows winemakers to produce three structurally very different styles from the same variety. Pergola trellis training is the traditional method in the region, though modern viticultural approaches are also used.

• Native Piedmontese variety with first written records from 1606
• High natural acidity enables dry, sparkling, and sweet wine production
• 100% Erbaluce required for all Erbaluce di Caluso DOCG styles
• Traditional training is pergola; modern methods also used

Erbaluce di Caluso DOCG produces three distinct styles. The dry white (bianco secco) shows white floral notes, lemon, stone fruit including apricot and peach, and a mineral, herbal character underpinned by bright acidity. The Spumante is made by Metodo Classico, requiring a minimum of 15 months on lees for secondary fermentation. The Passito is the appellation's rarest and most prized wine: production is microscopic, with some years yielding only 1,500 half-bottles. The Passito requires a minimum of four years aging, while the Passito Riserva requires 48 months. The grape's high acidity gives even the sweetest versions freshness and structure.

• Dry white: floral, citrus, stone fruit, mineral, herbal character
• Spumante: Metodo Classico with minimum 15 months second fermentation
• Passito: minimum 4 years aging; Riserva requires 48 months
• Passito production can be as low as 1,500 half-bottles in some vintages

Erbaluce di Caluso holds DOCG status, the highest tier in Italy's wine classification system, granted in 2010 after 43 years as a DOC from 1967. The grape itself has deep historical roots: the first written record dates to 1606, and Erbaluce won a gold medal at the 1855 Paris Exhibition. Today around 50 producers work within the appellation, generating approximately 1.5 million bottles per year across all three styles.

• DOC status granted 1967; elevated to DOCG in 2010
• First written record of Erbaluce dates to 1606
• Gold medal at the 1855 Paris Exhibition
• Approximately 50 producers and 1.5 million bottles annually
