The stages of champagne production

Champagne production is a complex process that unfolds in several distinct stages. Each stage of champagne production requires meticulous attention and expertise acquired over many years. Here is an overview of the main stages that transform grapes into champagne.

Grape harvest: Harvesting the grapes is the first key stage. It is usually done by hand to preserve the integrity of the bunches.

Pressing: The grapes are gently pressed to extract the juice without crushing the seeds, in order to avoid bitterness.

Fermentation: The juice obtained is fermented to turn it into wine. This stage is crucial for the development of aromas.

Blending: Wines from different vintages and years are blended to create a unique profile.

Secondary fermentation: The wine is bottled with sugar and yeast to undergo a second fermentation, creating the characteristic bubbles.

Ageing: The champagne is left to mature in the cellar for several years to develop its aromatic complexity.

Disgorging: The sediment is removed from the bottle, and a dosage is added to adjust the final flavour.

Every stage, from harvest to bottling, is essential to guarantee the quality and finesse of the champagne. Adherence to these stages of champagne production ensures the preservation of tradition and the excellence of the final product.

The grape varieties used in champagne production

Grape varieties play a decisive role in champagne production, influencing its taste, aroma and texture. The Champagne region is renowned for its three main grape varieties: Pinot Noir, Pinot Meunier and Chardonnay. Each contributes unique characteristics to the champagne.

Pinot Noir is often used for its structure and richness. Grown mainly in the Montagne de Reims, it gives champagne notes of red fruit and a lovely complexity. This grape variety is also prized for its ability to add depth and body to the wine.

Pinot Meunier, meanwhile, is known for its roundness and freshness. It is mainly grown in the Marne Valley. This grape variety brings fruity and floral aromas, contributing to the overall balance of the champagne. It is often used in the blend to soften and refresh the flavour profile.

Finally, Chardonnay is the white grape variety that brings elegance and finesse to champagne. Grown mainly in the Côte des Blancs, it offers notes of white flowers, citrus and, at times, minerality. Chardonnay is essential for champagnes of great purity and fine ageing potential.

The art of champagne-making lies in the careful selection and blending of these grape varieties, thereby creating perfect harmony and a unique flavour profile.

The grape harvest: the first key stage

The harvest is one of the most crucial stages in the production of champagne. It marks the start of the process of transforming grapes into wine. In Champagne, the harvest is generally carried out by hand, a tradition that helps to preserve the integrity of the bunches and select only the very best quality grapes.

Choosing the right time to harvest is essential to ensure the grapes reach optimal ripeness. Winegrowers closely monitor the sugar content and acidity of the grapes to determine the ideal time to harvest. This moment is crucial as it influences the final quality of the champagne. Grapes that are too ripe or not ripe enough can have a significant impact on the taste and balance of the wine.

During the harvest, the atmosphere is often cheerful and collaborative. It is a time of celebration for the winegrowers and their teams, as it marks the start of a new production season. It is also a period of intense and meticulous work, during which each bunch of grapes is carefully harvested and transported to the press for the next stage in the champagne-making process.

Fermentation: transforming juice into wine

Fermentation is a fundamental stage in the production of champagne, during which grape juice is transformed into wine. This complex process takes place in two distinct phases: alcoholic fermentation and malolactic fermentation.

Alcoholic fermentation is the first stage. It involves converting the sugars present in the grape juice into alcohol, through the action of natural or added yeasts. This conversion also produces carbon dioxide, which is released at this stage. It is during this phase that the wine acquires its initial aromas and basic structure.

After alcoholic fermentation, malolactic fermentation may take place. This stage is not always carried out but is often used to soften the wine and reduce its acidity. It converts malic acid, naturally present in the grapes, into lactic acid, which is milder. This process contributes to the aromatic complexity and balance of the champagne.

Mastering these fermentation processes is essential for the development of champagne’s flavour characteristics. Every choice and every adjustment made by the winemaker during these stages has a direct impact on the wine’s final profile. It is a delicate balance between science and art that few wine-growing regions master as well as Champagne.

Blending: the art of combining cuvées

Blending is a key stage in the production of champagne, where the winemaker’s artistry comes into its own. It involves blending wines from different cuvées, vintages and grape varieties to create a balanced and harmonious final product. This stage is often compared to composing a symphony, where every note must blend perfectly with the whole.

The aim of blending is to ensure the consistency and quality of the champagne from one year to the next. Reserve wines, set aside from previous harvests, are often used to enrich the blend and add further complexity. The winemaker’s expertise is evident in their ability to predict how the wines will develop together and to create a unique flavour profile.

During the blending process, each wine is carefully tasted and assessed to determine its potential contribution to the final blend. Characteristics such as acidity, aroma, texture and colour are taken into account. This process is often the result of many years’ experience and a refined palate. Blending is truly the heart and soul of champagne production, transforming the diversity of the cuvées into a sparkling work of art.

Malolactic fermentation: an essential stage

Malolactic fermentation is an optional but crucial stage in champagne production, which influences the drink’s taste and texture. This process involves converting malic acid, naturally present in wine, into the milder lactic acid. This conversion is carried out by specific lactic acid bacteria.

One of the main benefits of malolactic fermentation is that it reduces the wine’s acidity, making it smoother and rounder on the palate. This is particularly important in cooler regions such as Champagne, where the grapes can be naturally more acidic. By lowering the acidity, this fermentation contributes to the overall balance of the champagne and its sensory profile.

As well as softening the wine, malolactic fermentation adds further aromas and flavours, such as notes of butter and cream. These characteristics are particularly appreciated in certain styles of Champagne, where richness and complexity are sought after. The decision on whether or not to carry out malolactic fermentation is therefore a strategic one, depending on the style of champagne the winemaker wishes to produce.

Secondary fermentation: the secret of the bubbles

Secondary fermentation is the magical stage in champagne production, where the characteristic bubbles form. This process, also known as the second fermentation, takes place in the bottle and is crucial to the development of the champagne.

To initiate the second fermentation, a ‘liqueur de tirage’ – a mixture of sugar and yeast – is added to the still wine. The bottle is then sealed with a temporary cap. The yeast consumes the sugar and produces carbon dioxide, thereby creating the fine, persistent bubbles for which Champagne is renowned. This process generally lasts from several weeks to several months.

The secondary fermentation is followed by a period of ageing on the lees, during which the champagne remains in contact with the dead yeast cells, known as fine lees. This period is essential for the development of the champagne’s complex aromas and creamy texture. The longer the wine remains on the lees, the greater its depth and richness. This stage is a perfect example of the patience and expertise required to produce champagne, transforming the drink into a unique sensory experience.

Ageing: maturation and the development of aromas

The ageing of champagne is a crucial stage that allows its aromas to develop and its flavours to mature. After the second fermentation, the bottles are stored in cool, dark cellars, often for several years, to achieve optimal complexity and finesse.

During ageing, the champagne rests on its lees, which contributes to the enrichment of its aromas and the improvement of its texture. The aromas evolve, shifting from fruity and floral notes to more complex notes of toast, nuts and honey. The duration of ageing depends on the style of champagne being produced, with some ageing for over ten years.

Ageing on the lees is enhanced by the riddling process, in which the bottles are regularly rotated and tilted so that the lees gradually settle in the neck of the bottle. This stage prepares the champagne for disgorgement, allowing the deposits to be removed without affecting the clarity of the wine. Ageing is one of the reasons why champagne is so highly prized, offering a depth of flavour and complexity that can only be achieved over time.

Disgorging and dosage: putting the finishing touches to the creation

Disgorging is a fascinating stage that marks the end of the champagne-making process. This operation involves removing the lees that have accumulated in the neck of the bottle. It is traditionally carried out by freezing the neck of the bottle, followed by the expulsion of the ice plug containing the sediment. This technique ensures a crystal-clear and brilliant champagne.

After disgorging comes dosage, a stage at which a ‘liqueur d’expédition’ – a mixture of wine and sugar – is added to adjust the champagne’s final flavour. Dosage determines the level of sweetness in the champagne, ranging from brut nature (no added sugar) to demi-sec (sweeter). The choice of dosage is crucial, as it influences the balance and perception of the champagne’s aromas.

Disgorging and dosage are pivotal moments in champagne production, as they determine the final character of the product. These stages require exceptional precision and expertise to ensure that every bottle offers an unforgettable tasting experience. It is the culmination of years of hard work and passion, resulting in a drink worthy of the greatest celebrations.

Contemporary challenges in champagne production

Today, champagne production faces several contemporary challenges, which are driving winemakers to innovate whilst preserving traditions. Among these challenges, climate change is one of the most pressing, affecting the ripening cycles of the grapes and the quality of the harvest.

Temperature fluctuations and unpredictable weather conditions are forcing producers to adapt their viticultural practices. Some are exploring new sustainable viticulture techniques to protect the vines and preserve the ecological balance. The search for more resilient grape varieties and experimentation with new cultivation methods are among the strategies being implemented to adapt to these changes.

Furthermore, the growing demand for organic and sustainable products is prompting Champagne producers to review their production methods. More and more estates are turning to organic or biodynamic viticulture, reducing the use of chemicals and promoting environmentally friendly practices. These initiatives meet consumer expectations whilst preserving the quality and authenticity of champagne.
