Classic Method

Classic method

The production of wine using the Classic Method represents an ancient art based on a natural and complex fermentation process.

The Classic Method, also known as the Traditional Method or Champagne Method, is widely used in the production of high-quality sparkling wines.

One of its distinctive features is the secondary fermentation that occurs in the bottle, giving the wine its fine and persistent bubbles. During this process, a special yeast called liqueur de tirage is added to the base wine, initiating fermentation inside the bottle.

The interaction between the yeast and the wine produces carbon dioxide, which dissolves into the liquid, forming the precious bubbles. After this bottle fermentation, the wine rests on the lees for a variable period of time, ranging from months to years. It is during this phase that aromas and complexities develop, contributing to the fascinating character of the final wine.

At the end of the aging period, the lees are removed through a process known as disgorgement, which clarifies the wine, making it clear and transparent.

Finally, a small amount of dosage liquid is added, which can be a mixture of wine and sugar, to adjust the level of sweetness and complete the wine.

Charmat Method

The production of wine using the Charmat method, on the other hand, represents a modern and popular technique for producing sparkling wines.

This method, also known as the Martinotti method, is based on fermentation in autoclaves, offering numerous advantages in terms of efficiency and cost.

During the production process, the base wine is transferred to an autoclave, where sugar and yeast are added to initiate fermentation. During this phase, the carbon dioxide gas produced dissolves into the wine, creating the lively bubbles that characterize sparkling wines. Once fermentation is complete, the wine is clarified and filtered to remove yeast residues.

The Charmat method is appreciated for its ability to preserve the delicate aromas of the grapes used and for producing fruity and fresh sparkling wines. Furthermore, it allows for greater consistency in the quality of the final product, making it a popular choice for both producers and consumers.

Differences between the Classic Method and Charmat Method

The main differences between the Classic Method and the Charmat Method in the production of sparkling wines include the fermentation process, aging time, aroma and complexity of the wine, as well as production costs.

The Classic Method offers a traditional and lengthy process, ideal for those seeking complexity and rich aromas. The Charmat Method, on the other hand, is a practical and efficient choice that produces lively and fruity sparkling wines. The choice between the two methods will depend on personal preferences and the occasion in which you want to enjoy these excellent bubbles.

In the Classic Method, the base wine rests on the lees for a variable period of time, which can last several years. This process imparts greater aromatic complexity, character, and depth to the wine. However, it requires more time and care in production.

In the Charmat Method, fermentation occurs in autoclaves. The base wine is mixed with sugar and yeast inside a large sealed container. The carbon dioxide gas produced during fermentation dissolves into the wine, creating the bubbles. The duration of this process is generally shorter compared to the Classic Method, ranging from a few weeks to a few months. Wines produced with the Charmat Method often exhibit a fresh fruity aroma and immediate drinkability.

Lastly, production costs are generally higher for the Classic Method due to the extended aging period and technical complexities involved. The Charmat Method, on the other hand, is more cost-effective and allows for larger-scale production.

Gastronomic pairings: when to choose the classic method and when to choose the charmat method?

abbinamenti gastronomici

Discovering the ideal gastronomic pairings for the Classic Method and the Charmat Method is a delight for the palate and a unique sensory experience.

The Classic Method, with its elegance and complexity, pairs magnificently with refined and sophisticated dishes such as fresh oysters, fish carpaccio, or tartare-based appetizers. Its fine and persistent bubbles and enveloping aromas harmonize beautifully with the delicate flavors of seafood.

On the other hand, the Charmat Method, with its fruity and fresh sparkling wines, is perfect for accompanying informal aperitifs, appetizers, and lighter fish dishes. Enjoying a Charmat Method wine with vegetable crudités or fresh cheeses can enhance its pleasantness and drinkability. Furthermore, its lively bubbles and fruity flavor combine wonderfully with dishes such as sushi or tempura.

Whether you choose the Classic Method for special occasions or the Charmat Method for a more casual experience, both offer a wide range of culinary pairings, making every moment an unforgettable opportunity for taste and pleasure.
