The trend testifies to the growing global appreciation for the quality of the ‘mountain bubbles‘ Italian, supported by international awards and strategies of  qualitative positioning in the high-spending segments.

Genesis of a myth: from Giulio Ferrari to DOC recognition

The history of the  Trento DOC sparkling wine has its roots in  Italian classic method. The production of sparkling wine in Trentino dates back to the early 20th century, with pioneering figures such as  Giulio Ferrari, who in 1902 introduced the cultivation of  Chardonnay in Italy and laid the foundations for the evolution of ‘mountain bubbles’. Ferrari, trained in Champagne, imported not only the grape varieties but also the French winemaking techniques, adapting them to the Trentino alpine territory.

In the following years, thanks to the vision of Ferrari and other enlightened producers such as the  Lunelli (who acquired the Ferrari winery in 1952), the area developed a rigorous production identity. The recognition of the  Controlled Designation of Origin (DOC) for Trento sparkling wines dates back to  1993, affirming the territorial and qualitative specificity of the product.

The  production regulations, among the most restrictive in Italy for sparkling wines, has consolidated over the years the name ‘Trentodoc‘ as a synonym of high-quality Italian classic method sparkling wine, thanks to the combination of  alpine climate, high altitudes, selected grape varieties, and extended aging on the yeasts.

The strictness of the regulation: altitude and resilient viticulture

Terroir

The  Trentodoc is born in the autonomous province of Trento, a territory characterized by mountain microclimates, altitudes reaching 900 meters above sea level and a strong temperature excursion between day and night, which can exceed 15°C in the summer months. These climatic conditions, combined with soils mainly  limestone e dolomitic with good drainage, contribute to giving the grapes a high natural acidity and optimal phenolic ripening, fundamental elements for the production of fine, complex, and long-lasting sparkling wines.

The constant ventilation guaranteed by Alpine winds and the intense brightness of the Trentino valleys favor the health of the grapes and the aromatic concentration, creating ideal conditions for the classic method.

Grapevines

The  disciplinary regulations allows the exclusive use of grape varieties  Vitis vinifera traditional for the classic method sparkling wine:

• Chardonnay (main grape variety, represents over 70% of the vineyard area);

• Pinot Noir;

• Pinot Blanc;

• Pinot Meunier (in limited percentages).

The predominance of Chardonnay ensures freshness, mineral structure and evolutionary potential even over long aging periods. Pinot Noir provides body, complexity, and longevity, while Pinot Blanc contributes floral notes and aromatic delicacy.

Agronomic practices and sustainability

The  agronomic practices are increasingly oriented towards  environmental sustainability, with attention to:

• balanced management of  soil through grassing and green manures;

• drastic reduction of  pesticides of synthetic origin;

• promotion of  organic viticulture and certified biodynamic;

• protection of  biodiversity of mountain vineyards;

• rational management of water resources.

An increasing number of Trentodoc producers today adopt  organic certifications or have started conversion processes, reflecting the territory's commitment to low environmental impact practices.

The mountains and hill systems promote resilient agriculture that enhances grape quality from the vineyard, reducing the need for corrective interventions in the winery.

Production process

The production of  Trentodoc follows strictly the  classic method (Méthode Champenoise), which includes:

1. Manual harvest of ripe grapes but with high natural acidity (pH 2.9-3.1);

2. First fermentation alcoholic fermentation of the base wines vinified in steel or wood;

3. Assemblage of the cuvées (blend of base wines, vintages and grape varieties);

4. Tirage and second fermentation in the bottle with  prise de mousse;

5. Aging on the lees (sur lie) for minimum periods of:
   • 15 months for the basic Trento DOC;
   • 24 months for the Trento DOC  Vintage;
   • 36 months for the Trento DOC  Reserve;

6. Riddling (manual or mechanical disgorging);

7. Disgorgement (removal of sediment);

8. Final dosage (liqueur d’expédition) and corking with a mushroom cork.

Most Trentodoc producers widely exceed the legal minimums, with aging periods reaching 60-120 months for the  Reserves most prestigious. The 'art of the traditional method' is what distinguishes Trentodoc production, imparting aromatic complexity,  Perlage very fine and persistent, and a balanced gustatory structure.

Label transparency: the Trentodoc brand and value protection

The labeling of Trento DOC sparkling wine is an element of transparency and protection of value. A distinctive aspect is the use of the collective brand Trentodoc (written as a single word), designed by Maurizio Di Robilant. This logo uniquely identifies the traditional method sparkling wine produced in Trentino, clearly distinguishing it from other types of bubbles.

Mandatory and optional phrases follow strict standards to ensure traceability:

• DOC designation: the wording ‘Trento’ followed by ‘Denominazione di Origine Controllata’ and ‘Metodo Classico’ certifies compliance with the regulations;

• Date of disgorgement (disgorgement): its indication on the label is an increasingly widespread and appreciated practice to assess the freshness and evolutionary stage of the wine;

• Sugar classification (EU regulation 1308/13): zero dosage or Brut Nature (

• Vintage and Reserve. The indication of the grape harvest year (vintage) is mandatory for wines aged at least 24 months, while the mention ‘Reserve’ is reserved for products that exceed 36 months of lees aging.

Sensory identity: dolomitic minerality and perlage

The  Trento DOC presents a distinctive organoleptic profile that characterizes it in the landscape of  traditional method sparkling wines:

• visual aspect: bright straw yellow color, with greenish reflections in the young versions and  golden in the Reserves. Fine, persistent and continuous perlage;

• aromatic profile: notes of  citrus fruits (grapefruit, cedar), white flowers (acacia, hawthorn), white pulp fruit (green apple, pear),  almond and toasted hazelnut. In the more evolved versions there are scents of  bread crust, brioche, acacia honey and noble hydrocarbons that recall the minerality of the territory;

• taste: vibrant freshness supported by  natural acidity (pH 3.0-3.2), savoury and mineral structure, elegant body and aromatic persistence. The finish is clean, with citrus returns and  almondy. The dosage (generally  Brut o Extra Brut) is calibrated to enhance the expressive purity of the territory.

The component  mineral deriving from limestone and dolomitic soils represents the most recognizable identity trait of Trentodoc compared to other Italian traditional methods.

The ‘Champagne & Sparkling Wine World Championships’ (CSWWC) 2024 – founded and led by Tom Stevenson, one of the most authoritative voices internationally in the sparkling wine scene – awarded Trentodoc a total of 73 recognitions (29 gold medals and 44 silver medals. CSWWC, 2026).

• more structured versions and  vintage go well with risottos, creamy first courses and aged hard cheeses;
