The Art and Science of Making Prosecco

by Kaia

Prosecco, the sparkling Italian wine known for its crisp and effervescent character, has been enjoyed for centuries. This beloved bubbly, hailing from the Veneto and Friuli Venezia Giulia regions of Italy, has a distinct charm and appeal. In this comprehensive guide, we will uncover the intricate process of making Prosecco, exploring its origins, grape varieties, production methods, and the regional traditions that contribute to its unique character.


Prosecco’s Historical Roots

The history of Prosecco can be traced back to the Veneto region, where it has been produced for over three centuries. The grape variety used to make Prosecco, Glera (formerly known as Prosecco), was named after the village of Prosecco near Trieste. The first documented mention of Prosecco as a wine comes from a letter dated 1754.


The Grape Varieties of Prosecco

Prosecco is primarily made from Glera grapes, but the regulations governing its production allow for the inclusion of other grape varieties in limited quantities. The Glera grape is renowned for its high acidity and bright fruitiness, which contribute to Prosecco’s fresh and lively character.


In addition to Glera, small proportions of other grapes like Verdiso, Bianchetta, Perera, Glera Lunga, and Chardonnay may be used, typically accounting for no more than 15% of the total blend. These secondary grapes can add complexity and nuances to the final Prosecco wine.


The Prosecco Wine Production Process

The production of Prosecco involves several key steps, from grape cultivation to bottling, each contributing to its signature flavor and effervescence.

Grape Harvest: The process begins with the harvest of Glera grapes in the vineyards. The grapes are typically handpicked to ensure that only the ripest clusters are selected.

Soft Pressing: After harvest, the grapes are gently pressed to extract the juice. This step is crucial to maintain the freshness and fruitiness of the wine.

Fermentation: The juice undergoes the primary fermentation, which transforms the grape sugars into alcohol. This fermentation usually takes place in temperature-controlled stainless steel tanks to preserve the delicate flavors of the grapes.

Assemblage: In Prosecco production, it’s common to create a blend of wines from different vineyard sites and vintages. This blending, known as assemblage, allows producers to craft a consistent and balanced flavor profile.

Secondary Fermentation: Prosecco is made using the Charmat-Martinotti method, a distinct and time-efficient technique. In this process, the assemblage is placed in a pressurized tank along with selected yeasts and sugar. As a result of the secondary fermentation, carbon dioxide is trapped in the wine, creating the characteristic bubbles. This method helps preserve the wine’s fruity character and delicate aromas.

Aging: Prosecco wines generally undergo a brief aging period to allow the flavors to harmonize. However, the aging process is shorter compared to traditional methods of sparkling wines like Champagne. Prosecco labeled as “Non-vintage” (NV) typically has a minimum aging period of 60 days, while vintage Prosecco is aged for a minimum of 3 months.

Filtration and Stabilization: Prior to bottling, the wine undergoes filtration to remove yeast residues, ensuring clarity. Producers may also stabilize the wine by cooling it to prevent further fermentation and retain its desired sweetness level.

Bottling: Prosecco is bottled under pressure to preserve its effervescence. The cork, often secured with a wire hood, is crucial to withstand the pressure and seal in the bubbles.

Prosecco Styles

Prosecco comes in different styles, each distinguished by its sweetness level:

Brut: This is the driest style of Prosecco, with minimal residual sugar. It offers a crisp and refreshing taste.

Extra Dry: Despite the name, Extra Dry Prosecco is actually slightly sweet. It strikes a balance between dry and off-dry, making it a versatile choice for various occasions.

Dry: Dry Prosecco has a subtle sweetness, which enhances its fruity character and approachability.

Extra Brut: Extra Brut Prosecco is the driest style, with nearly no residual sugar. It provides a very clean and crisp taste.

Gently Sweet (Semi-Seco): Gently sweet Prosecco is off-dry, offering a touch of sweetness alongside the wine’s fruitiness.

Sweet (Dolce): The sweetest style of Prosecco, dolce, is rich and luscious, making it an excellent choice for desserts.

Regional Traditions

The Prosecco production regions are divided into two distinct appellations: Prosecco DOC (Denominazione di Origine Controllata) and Prosecco DOCG (Denominazione di Origine Controllata e Garantita). The DOCG designation signifies a higher quality standard and stricter regulations.

Prosecco DOC covers a broader area, including nine provinces in Veneto and four in Friuli Venezia Giulia. It is the heartland of Prosecco production, with its rolling hills and vineyards.

Prosecco DOCG, on the other hand, is more limited in scope and is primarily centered around the Valdobbiadene and Conegliano regions. These hillsides are known for their exceptional terroir and ideal grape-growing conditions. Prosecco from these areas is often considered the finest and most sought-after.

Food Pairings with Prosecco

Prosecco’s versatile and vibrant character allows for a wide range of food pairings:

Antipasti: Prosecco complements a variety of Italian antipasti, from bruschetta to prosciutto-wrapped melon.

Seafood: Its crisp acidity makes Prosecco a fantastic match for seafood, such as oysters, sushi, or shrimp cocktails.

Cheeses: Soft cheeses like brie and camembert pair wonderfully with Prosecco. It also works well with salty, hard cheeses.

Salads: The fresh and fruity notes of Prosecco enhance salads with vinaigrette dressings, making it an excellent choice for appetizers.

Light Pasta Dishes: Prosecco complements dishes like pasta primavera and light cream sauces.

Fried Foods: The wine’s effervescence and acidity cut through the richness of fried foods, such as calamari or tempura.


Prosecco, with its centuries-old heritage and modern winemaking techniques, continues to captivate wine lovers with its lively bubbles, fruity character, and versatility. From the vineyards of Veneto and Friuli Venezia Giulia to your glass, Prosecco is a symbol of celebration and conviviality.
