Moscato Bianco

Moscato Bianco, known internationally as Muscat Blanc à Petits Grains, is a grape variety of Greek origin that was likely introduced to the Italian peninsula via ancient Greek trading routes. The ancient Romans prized it under the name apiana, a reference to its honeyed fragrance that attracted bees. In Piedmont, written records confirming the grape's presence date to the 14th century, and by the 16th century Langa growers were required to include a proportion of it in their vineyards. The pivotal modern chapter began in 1865 when Carlo Gancia of Canelli travelled to Champagne, returned with sparkling-wine techniques, and applied them to Moscato grapes, founding the tradition that would eventually underpin the Asti DOCG. In 1606, Giovanni Battista Croce, jeweller to the Dukes of Savoy, wrote the first scientific treatise on Moscato cultivation and winemaking in the region.

• Muscat Blanc à Petits Grains is of Greek origin and was likely spread westward through ancient Greek and Roman trade networks
• Ancient Roman writers referred to the grape as apiana, named for its sweet, honeyed scent that attracted bees
• Written records confirm Moscato Bianco cultivation in Piedmont from at least the 14th century
• Carlo Gancia pioneered modern sparkling Moscato production at Canelli in 1865, using techniques learned in Champagne

Moscato Bianco reaches its finest expression in the rolling hills of southeastern Piedmont, specifically across 51 municipalities in the provinces of Asti, Alessandria, and Cuneo. The production zone encompasses approximately 9,800 hectares and forms part of the Langhe-Roero-Monferrato UNESCO World Heritage Site recognised in 2014. Vineyards are planted between 165 and 500 metres above sea level, where the optimal combination of limestone and sandstone soils, warm days, cool nights, and southern exposures allows aromatic compound development while preserving the natural acidity essential to the style. The historic town of Canelli sits at the geographic and cultural heart of the zone; its 17 surrounding municipalities now form the newly independent Canelli DOCG, elevated in 2023 as the appellation's most prestigious designation.

• The Asti DOCG covers approximately 9,800 hectares across 51 municipalities in the provinces of Asti, Alessandria, and Cuneo
• Limestone and sandstone soils provide ideal hydration and enhance the grape's characteristic aromatic intensity
• Vineyards must be sited between 165 and 500 metres above sea level under DOCG regulations
• In 2023, the 17 municipalities around Canelli were elevated to their own independent Canelli DOCG, Piedmont's 19th DOCG designation

Moscato Bianco delivers an immediately recognisable aromatic signature dominated by white flowers such as orange blossom and honeysuckle, stone fruits including peach and apricot, and citrus notes. These characteristics are driven by monoterpene compounds, principally linalool, geraniol, and nerol, which accumulate in the berry skin during ripening and carry through intact into the wine due to the low-intervention winemaking approach. On the palate, Moscato d'Asti presents gentle frizzante effervescence at a maximum of 2.5 atmospheres of pressure, a silky texture from approximately 100 g/L of residual sugar, and a refreshing finish supported by bright natural acidity. Asti Spumante, produced by a secondary fermentation in pressurised tanks, shows a more pronounced sparkle and slightly higher alcohol, typically reaching 7 to 9% ABV.

• Primary aromas are driven by monoterpenes including linalool, geraniol, and nerol, the same compounds responsible for floral and citrus notes in Riesling and Gewurztraminer
• Moscato d'Asti has a maximum pressure of 2.5 atmospheres, creating gentle frizzante effervescence distinct from the fuller fizz of Asti Spumante
• Residual sugar of approximately 100 g/L provides textural richness and sweetness that is balanced by the variety's naturally high acidity
• Asti Spumante reaches between 7 and 9% ABV, while Moscato d'Asti is capped at 6.5% ABV by DOCG regulations

Moscato d'Asti is produced using a carefully controlled partial fermentation method. The freshly pressed must is stored at near-freezing temperatures to prevent spontaneous fermentation, then the temperature is raised and yeast is added to begin a slow, monitored fermentation in pressurised tanks. When the desired alcohol level of around 5 to 5.5% ABV is reached, the wine is chilled rapidly and the yeast removed by filtration, arresting fermentation and retaining both residual sugar and the dissolved carbon dioxide responsible for the wine's gentle effervescence. No secondary fermentation in the bottle is permitted. The entire process prioritises preserving the grape's primary aromatic compounds, so stainless steel tanks, cold handling, and minimal intervention are universal standards. Malolactic fermentation is avoided to maintain the crisp acidity that defines the style.

• Must is stored at near-freezing temperatures after pressing to prevent spontaneous fermentation before controlled fermentation begins
• Fermentation is arrested by rapid chilling and filtration when the wine reaches approximately 5 to 5.5% ABV, retaining residual sugar
• No secondary fermentation in the bottle is permitted for Moscato d'Asti; the wine's effervescence comes solely from CO2 produced during the interrupted primary fermentation
• Stainless steel tank vinification with temperature control is universal; oak contact is avoided to preserve primary fruit and floral aromatics

Paolo Saracco, based in Castiglione Tinella, is widely regarded as the benchmark producer of Moscato d'Asti. Saracco began estate bottling in 1988 and has since built a reputation for consistency, earning over 15 consecutive years of 90-plus scores from major wine publications. His wines are vinified in stainless steel and bottled in small weekly batches to guarantee freshness. Michele Chiarlo's Nivole is one of the category's most recognised labels, sourcing Moscato Bianco from vineyards in the hills around Canelli at 5% ABV. The Bera family, who were the first to estate-bottle Moscato d'Asti in 1964, now produce under the new Canelli DOCG designation, with organically farmed vines averaging 40 years of age. Other reliable producers include Ceretto, Cascina Fonda, and La Spinetta.

• Michele Chiarlo's Nivole is sourced from Canelli-area vineyards and fermented to 5% ABV, named after the Piedmontese word for clouds
• The Bera family were the first to estate-bottle Moscato d'Asti in 1964 and now produce under the premium Canelli DOCG designation with certified-organic farming
• Other respected producers include Ceretto, Cascina Fonda, La Spinetta, and Forteto della Luja

Moscato Bianco is susceptible to powdery mildew, grey rot, and the grape berry moth, requiring attentive canopy management and thoughtful site selection. Yields are capped at 10 tonnes per hectare across the Asti DOCG, with grape must conversion limited to 75 litres per 100 kg. The steepest vineyards, known locally as sorit, carry slopes exceeding 40% and must be tended entirely by hand; over 1,400 hectares of the zone qualify as heroic viticulture. The 2023 elevation of the Canelli subzone to independent DOCG status, covering 17 municipalities around the town of Canelli at a minimum altitude of 165 metres, represents the most significant regulatory development for the category in decades, creating a higher tier focused on quality and provenance. The broader Asti DOCG hillscapes were inscribed as a UNESCO World Heritage Site in 2014.

• DOCG regulations cap yields at 10 tonnes per hectare and limit must conversion to 75 litres per 100 kg of grapes
• Over 1,400 hectares of Asti DOCG vineyards have slopes exceeding 40%, classified as heroic viticulture and worked entirely by hand
• The Canelli DOCG, formalised in 2023, covers 17 municipalities and requires vineyards above 165 metres altitude
• The Langhe-Roero-Monferrato vineyard landscapes, encompassing core Moscato d'Asti areas, were inscribed as a UNESCO World Heritage Site in 2014
