Unveiling the World of Prosecco: A Comprehensive Guide

The effervescent Prosecco, a captivating sparkling wine, is experiencing a meteoric rise in global prominence and popularity. Transcending its humble origins, this vivacious beverage traces its roots to Roman times, flourishing in the scenic town of Prosecco in Northeast Italy. The first recorded mention of its enticing name, initially spelled as 'Prosecho,' can be attributed to the Englishman Fynes Moryson in 1593. Originally christened 'Ribolla,' its distinctive moniker arose from a quest to distinguish it from other wines bearing the same appellation.

This comprehensive guide delves into the enchanting world of Prosecco, unveiling its storied history, the intricacies of its production methods, the revered DOC and DOCG regions, and the nuances of its effervescence and sweetness levels. Furthermore, an exploration of the unique Col Fondo style promises to captivate enthusiasts with its artisanal allure, culminating in a harmonious conclusion that celebrates this sparkling wine's enduring charm.

The Grape: Glera

At the heart of Prosecco's captivating allure lies the Glera grape, a white variety deeply rooted in Italy's viticultural heritage. Thriving in the cool climate and hilly terrain of Northeast Italy, this grape revels in the region's fertile soils, imparting Prosecco with its signature crisp, fruity profile.

Formerly known as Prosecco, the Glera grape was renamed in 2009 to safeguard the protected geographical status of the Prosecco wine appellation. Despite its humble origins, possibly tracing back to the village of Prosecco near Trieste, Glera has ascended to become the thirtieth most significant grape variety among Italy's diverse viticultural tapestry.

Glera's Distinctive Traits

  • Delicate and Late-Ripening: Glera is a late-ripening grape prone to fungal diseases and water stress, necessitating meticulous cultivation practices.
  • Aromatic Elegance: When grown on south-facing slopes with controlled yields, Glera produces wines with depth and character, exuding aromas of white flowers, lemon, pear, apple, and peach.
  • Versatile Blending: While Glera is the primary grape in Prosecco, DOC and DOCG regulations permit up to 15% of other permitted varieties to be blended, contributing to the wine's complexity.

Glera's legacy extends beyond Prosecco, as it is a parent variety of the Manzoni grape varieties, Incrocio Manzoni 2.15 and Incrocio Manzoni 2.14, further underscoring its significance in Italian winemaking.

Production Methods

The production of Prosecco is a meticulously crafted process that combines traditional techniques with modern innovations. At the heart of this process lies the Charmat-Martinotti method, a unique approach that sets Prosecco apart from other sparkling wines.

The Charmat-Martinotti Method

  1. Base Wine Fermentation: The journey begins with the gentle pressing of the Glera grapes, extracting the free-run must. This must undergoes the first alcoholic fermentation, resulting in the base wine.
  2. Secondary Fermentation: The base wine is then transferred to pressurized stainless steel tanks, where the second fermentation takes place. This phase, known as the sparkling process, can last from 30 days to 6 months, during which the wine develops its signature effervescence.
  3. Bottling and Finishing: Once the desired level of effervescence is achieved, the Prosecco is bottled, typically between March and April when temperatures are mild. The bottles are then stored at a controlled temperature of 15-18°C, allowing the sparkling process to complete.

The Charmat-Martinotti method is not only more efficient and quicker than the traditional method used for Champagne, but it also preserves the aromatic qualities of the Glera grapes, resulting in a fruitier, more approachable sparkling wine.

Innovation and Adaptation

The prosecco industry continues to innovate, introducing new techniques, organic and vegan variants, and adapting to changing consumer preferences. Producers like Valdo take care of the entire production process, from harvesting to bottling, ensuring quality and traceability. Additionally, the establishment of robust knowledge networks throughout the value chain facilitates internationalization and the adoption of best practices.

Prosecco's DOC and DOCG Regions

The prosecco industry is governed by a strict quality assurance system, with different designations reflecting the wine's provenance and production methods. At the forefront lies the prestigious Conegliano Valdobbiadene DOCG region, a UNESCO World Heritage Site nestled in the foothills of the Alps. This compact area, spanning just 19 x 16 miles (30 x 25 km), is renowned for its steep, southern-facing slopes and unique terroir, yielding fresh, aromatic, and refined sparkling wine.

Within the Conegliano Valdobbiadene DOCG, three distinct tiers exist:

  1. Prosecco Superiore DOCG: This category encompasses the entire region, adhering to stringent regulations, including a maximum yield of 13.5 tonnes/ha (compared to 18 tonnes/ha in the Prosecco DOC).
  2. Prosecco Superiore Rive DOCG: Representing the pinnacle of quality, this designation is reserved for wines crafted from grapes grown in the steepest vineyards across 43 villages, known for their elegance and structure.
  3. Valdobbiadene Superiore di Cartizze DOCG: Considered the "jewel in the crown," this tiny 267-acre (108 ha) area produces the most delicate and perfumed prosecco wine, revered for its exceptional finesse.

Beyond the Conegliano Valdobbiadene DOCG, the broader Prosecco DOC region encompasses nine provinces across Veneto and Friuli-Venezia Giulia, spanning 28,100 hectares and producing an average of 627 million bottles annually. This region is further divided into three styles:prosecco brut (spumante),prosecco cocktails (frizzante), and still (tranquillo).

While the Prosecco DOC region offers a broader range of styles, the Conegliano Valdobbiadene DOCG stands as the pinnacle of prosecco vs champagne, embodying the essence of this iconic sparkling wine through its unique terroir and meticulous production methods.

Effervescence and Sweetness Levels

Prosecco's effervescence and sweetness levels are integral to its alluring character, offering a range of styles to suit every palate. The prosecco industry meticulously categorizes these wines based on their residual sugar content and level of fizz or 'perlage.'

Sweetness Spectrum

Prosecco is available in six distinct sweetness levels, ranging from the driest Brut Nature to the sweetest Demi-Sec. This spectrum caters to diverse preferences, allowing enthusiasts to savor the wine's nuances:

Sweetness Level

Residual Sugar (g/l)


Brut Nature


Bone dry

Extra Brut


Very dry




Extra Dry


Medium dry (dry with a hint of sweetness)



Medium sweet




Interestingly, the term 'Extra Dry' can be confusing, as it denotes a sweeter style than 'Brut.' Mass-produced prosecco wine often falls into the Extra Dry category, with a touch of extra sugar to enhance its taste. However, higher-quality Proseccos from artisan wineries tend to favor the drier Brut and Extra Brut styles, showcasing the grape's natural elegance.

Effervescence Levels

The level of effervescence, or 'perlage,' is another defining characteristic of prosecco vs champagne. Prosecco can be either frizzante (lightly sparkling) or spumante (fully sparkling), with the latter being the most common and celebrated style. Within the spumante category, three levels of fizz are recognized:

  1. Spumante (Most bubbly)
  2. Frizzante (Moderately bubbly)
  3. Tranquillo (Still)

The Bella Principessa Premium prosecco brut is renowned for its exceptional quality, refined bubbles, and delightful apple, pear, and white peach notes, exemplifying the harmonious balance of effervescence and flavour that prosecco cocktails enthusiasts seek.

Unique Styles: Col Fondo

Among the diverse styles of prosecco, the artisanal Col Fondo method stands out as a true expression of tradition and craftsmanship. This unique approach, which translates to "with sediment," harks back to the ancient Roman practice of refermentation in the bottle, resulting in a complex and distinctive sparkling wine.

The Col Fondo Process

  1. Base Wine Fermentation: The journey begins with the gentle pressing of the Glera grapes, followed by the initial fermentation to produce the base wine.
  2. Refermentation in the Bottle: Unlike the Charmat-Martinotti method, Col Fondoprosecco wine undergoes its second fermentation directly in the bottle, where the spent yeast cells remain, contributing to the wine's distinctive character.
  3. Aging and Riddling: The bottles are then aged sur lie (on the lees) for an extended period, typically ranging from several months to a year or more. During this time, the bottles are periodically riddled (rotated) to collect the sediment in the neck of the bottle.
  4. Disgorging and Finishing: Finally, the sediment is disgorged (removed), and the bottle is topped up with a small amount of the same wine, creating a cloudy, slightly effervescent sparkling wine with a unique, yeasty aroma and flavour profile.

Col Fondo prosecco cocktails offer a distinct and captivating experience, appealing to enthusiasts who appreciate the nuances of traditional winemaking methods and the depth of flavours imparted by extended lees contact. While less common than the Charmat-Martinotti style, this unique approach showcases the versatility and heritage of the prosecco tradition.
