Prosecco DOC

Prosecco's name derives from the village of Prosecco near Trieste, on the Slovenia-Italy border, where the grape was traditionally believed to originate. For centuries the wine was a regional Veneto sparkling specialty, but by the 2000s rising international demand and the use of the Prosecco name by producers in Australia, Brazil, and elsewhere prompted Italian authorities to act. In 2009, two pivotal decisions reshaped the category: first, the grape was officially renamed from Prosecco to Glera, legally separating grape variety from geographic denomination; second, the various Prosecco IGTs were unified into a single Prosecco DOC, with the existing hillside Conegliano Valdobbiadene zone elevated to DOCG and a new Asolo Prosecco DOCG also created. The result was a hierarchical pyramid: Prosecco DOC at the base (nine provinces, flatland and lower foothill), Asolo Prosecco DOCG and Conegliano Valdobbiadene Prosecco Superiore DOCG at the top (hillside). Carpenè Malvolti, founded in Conegliano in 1868, is credited as the first commercial Prosecco house.

• Pre-2009: Prosecco wines bottled under Prosecco di Conegliano Valdobbiadene DOC + various Veneto/Friuli IGTs
• 2009 changes: grape renamed Prosecco → Glera; IGTs unified into Prosecco DOC; Conegliano Valdobbiadene elevated to DOCG; Asolo Prosecco DOCG created
• Renaming purpose: prevent overseas producers from using 'Prosecco' on labels by citing grape variety name (paralleling French Champagne protection)
• Carpenè Malvolti (founded 1868 in Conegliano): credited as Italy's first commercial sparkling Prosecco house

Prosecco DOC's vast 28,100-hectare zone spans nine provinces across two regions: Veneto (Belluno, Padova, Treviso, Venezia, Vicenza) and Friuli-Venezia Giulia (Gorizia, Pordenone, Trieste, Udine). The Treviso province is the historical heartland and produces a designated Prosecco DOC Treviso sub-category; the Trieste province has its own Prosecco DOC Trieste sub-category honouring the grape's birthplace. Most Prosecco DOC vineyards sit on flatland or gentle foothills, distinguishing the wines from the steep-hillside DOCG zones of Conegliano Valdobbiadene and Asolo. Soils vary from alluvial clay-loam in the eastern Veneto plain to morainic gravel and limestone in foothill sites near the Alps. The continental climate is moderated by the Adriatic to the south and the Pre-Alps to the north. Yields are capped at 18 tonnes per hectare, considerably higher than the hillside DOCG zones' 13.5 t/ha cap.

• Nine-province zone: Veneto (Belluno, Padova, Treviso, Venezia, Vicenza) + Friuli-Venezia Giulia (Gorizia, Pordenone, Trieste, Udine)
• Sub-categories: Prosecco DOC Treviso (added 2009, historical heartland); Prosecco DOC Trieste (grape's birthplace)
• Mostly flatland and gentle foothill vineyards; soils vary from alluvial clay-loam (eastern plain) to morainic gravel and limestone (foothills)
• Yields capped at 18 t/ha (vs 13.5 t/ha in Conegliano Valdobbiadene DOCG); higher productivity supports volume-driven economics

Glera (renamed from Prosecco in 2009) must comprise minimum 85% of every Prosecco DOC blend. Up to 15% may come from Verdiso, Bianchetta Trevigiana, Perera, Glera Lunga, Chardonnay, Pinot Bianco, Pinot Grigio, and Pinot Nero vinified white (Pinot Nero vinified red is permitted in Prosecco DOC Rosé). The Charmat method (Martinotti method in Italy) drives virtually all production: secondary fermentation occurs in large pressurised stainless steel autoclave tanks for typically 30-60 days, preserving Glera's delicate primary fruit and floral aromatics that traditional method autolysis would mask. The dosage spectrum runs from Brut Nature (0-3 g/L residual sugar) and Extra Brut (0-6 g/L) through Brut (up to 12 g/L, the most popular global export style), Extra Dry (12-17 g/L, the historical dominant Italian style), and Dry (17-32 g/L). Frizzante (light effervescence, ~2.5 atmospheres pressure) and Spumante (full sparkling, 3+ atmospheres) styles both exist; Spumante is by far the dominant commercial form.

• Minimum 85% Glera; up to 15% Verdiso, Bianchetta Trevigiana, Perera, Glera Lunga, Chardonnay, Pinot Bianco, Pinot Grigio, Pinot Nero (white-vinified)
• Charmat (Martinotti) method: secondary fermentation in pressurised autoclave tanks, typically 30-60 days; preserves Glera's primary aromatics
• Dosage range: Brut Nature (0-3 g/L), Extra Brut (0-6 g/L), Brut (up to 12 g/L, top global export style), Extra Dry (12-17 g/L, historical Italian style), Dry (17-32 g/L)
• Spumante (full sparkling, 3+ atmospheres) dominates commercial production; Frizzante (light effervescence, ~2.5 atmospheres) is a smaller traditional category

Prosecco DOC Rosé was officially introduced in 2020 after years of producer lobbying and represents a significant category expansion. The rules require 85-90% Glera and 10-15% Pinot Noir (Pinot Nero) vinified red, must be vintage-dated, and require a minimum 60 days of secondary fermentation (longer than standard Prosecco). The colour ranges from light salmon to pale onion-skin. Production reached approximately 80 million bottles in 2024, demonstrating strong market traction. The broader Prosecco quality pyramid places Prosecco DOC at the base (flatland/foothill, 18 t/ha) above the two DOCG hillside zones: Asolo Prosecco DOCG (Colli Asolani hills) and Conegliano Valdobbiadene Prosecco Superiore DOCG (UNESCO-listed hillsides, with 43 single-commune Rive bottlings and the Cartizze grand cru). The pyramid mirrors France's Champagne system without using cru terminology, with hillside DOCGs offering greater concentration and complexity than the volume-driven flatland DOC.

• Prosecco DOC Rosé (introduced 2020): 85-90% Glera + 10-15% Pinot Noir vinified red; must be vintage-dated; minimum 60 days secondary fermentation; light salmon to onion-skin colour
• Rosé production reached ~80 million bottles in 2024; rapidly growing category since 2020 launch
• Quality pyramid: Prosecco DOC (base, 18 t/ha) → Asolo Prosecco DOCG (hillside, 12 t/ha) → Conegliano Valdobbiadene Prosecco Superiore DOCG (UNESCO hillside, 13.5 t/ha)
• Hillside DOCG zones offer concentration and complexity beyond flatland DOC; Cartizze and 43 Rive bottlings are top tier

The Prosecco DOC category spans from large industrial-scale producers to small artisan family estates. Mionetto (founded 1887), Zonin (one of Italy's largest wine groups), La Marca, Riondo, and Carpenè Malvolti (Italy's oldest sparkling house) are among the largest commercial producers. Nino Franco (founded 1919, Valdobbiadene) operates across both Prosecco DOC and Conegliano Valdobbiadene Prosecco Superiore DOCG. The Consorzio di Tutela del Prosecco DOC oversees production rules and market protection; the Consorzio di Tutela del Conegliano Valdobbiadene Prosecco DOCG manages the higher-tier hillside zone. Prosecco DOC is intended for early consumption (within 1-2 years of bottling), is served chilled (6-8°C), and is best presented in a tulip or white wine glass to preserve perlage and concentrate the wine's aromatics. The annual Vinitaly trade fair in Verona each April is the category's primary commercial showcase.
