Prosecco, the renowned and highly popular Italian sparkling wine, has captured the hearts and palates of wine enthusiasts worldwide. This light and refreshing bubbly is often associated with celebration and joyous occasions. However, have you ever wondered what grape variety is used to make this beloved wine?

Prosecco is primarily made with the Glera grape, which is indigenous to northeastern Italy, specifically the Veneto and Friuli Venezia Giulia regions. Glera is a white grape with high acidity, making it an ideal choice for sparkling wine production. This grape variety has been cultivated in the Prosecco region for centuries, contributing to the unique character and flavor profile of this exquisite wine.

While Glera is the main grape used in Prosecco production, regulations allow for the inclusion of other local grape varieties in small percentages, such as Verdiso, Bianchetta Trevigiana, and Perera. These additional grape varieties can enhance the complexity and acidity of the final product, adding subtle nuances to the overall flavor.

It is worth noting that Prosecco can be produced in two different regions of Italy: the larger Prosecco DOC area and the smaller, more prestigious Conegliano Valdobbiadene DOCG region. Within the Conegliano Valdobbiadene region, the Prosecco Superiore designation is used for wines that adhere to stricter rules, indicating higher quality.

Now let’s explore the winemaking process for Prosecco. After the grapes are harvested, they undergo a gentle pressing to extract the juice. The must, or grape juice, is then transferred to stainless steel tanks for fermentation. Unlike other sparkling wines, Prosecco undergoes a second fermentation in a stainless steel tank, rather than in the bottle. This process is known as the Charmat method or the tank method.

During the Charmat method, a specific strain of yeast is added to the tank to initiate the second fermentation. This yeast consumes the sugar present in the grape must, producing carbon dioxide, which is trapped inside the tank. The result is the characteristic effervescence and delicate bubbles of Prosecco.

After the second fermentation, the wine is left to rest on its lees, the dead yeast cells, for a period of time. This lees aging contributes to the wine’s complexity and adds subtle flavors and aromas. Depending on the desired style of Prosecco, the aging period can vary from a few months to several years.

Once the aging process is complete, the winemaker filters out the lees and adds a small amount of sugar, known as dosage, to balance the acidity and enhance the wine’s aromatic profile. The final step involves bottling the wine under pressure to preserve its effervescence and release it to consumers.

The result is a delightful and versatile sparkling wine with a straw yellow color, lively bubbles, and delicate floral and fruity aromas. Prosecco typically exhibits notes of green apple, pear, citrus, and white flowers on the palate, with a crisp and refreshing finish. It is known for its light to medium body and lower alcohol content compared to other sparkling wines, making it perfect for casual gatherings, brunches, and aperitivos.

In conclusion, Prosecco is primarily made with the Glera grape, along with small percentages of other local grape varieties. Its production follows the Charmat method, characterized by the second fermentation taking place in stainless steel tanks. The result is a lively and elegant sparkling wine that has become a symbol of celebration and joy. So, next time you raise a glass of Prosecco, you can appreciate the craftsmanship and meticulous winemaking process that goes into creating this beloved Italian sparkling wine.
