Stages in the champagne-making process
Champagne-making is a complex process involving several distinct stages. Each step in the champagne-making process requires meticulous attention and expertise acquired over many years. Here is an overview of the main stages that transform grapes into champagne.
HarvestGrape harvesting is the first key stage. It is generally done by hand to preserve the integrity of the bunches.
Pressing: The grapes are gently pressed to extract the juice without crushing the seeds, to avoid bitterness.
Fermentation: The resulting juice is fermented to turn it into wine. This stage is crucial for the development of aromas.
Blending: Wines from different cuvées and vintages are blended to create a unique profile.
Secondary Fermentation: The wine is bottled with sugar and yeast to trigger a second fermentation, creating the characteristic bubbles.
Ageing: Champagne is left to age in the cellar for several years to develop its aromatic complexity.
Riddling: The sediment is removed from the bottle, and a dosage liqueur is added to adjust the final flavour.
Each stage, from harvesting to bottling, is essential to guarantee the quality and finesse of champagne. Adhering to these steps in the champagne-making process ensures the preservation of tradition and the excellence of the final product.
Grape varieties used in champagne production
Grape varieties play a key role in champagne production, influencing taste, aroma and texture. The Champagne region is renowned for its three main grape varieties: Pinot Noir, Pinot Meunier and Chardonnay. Each brings unique characteristics to Champagne.
Pinot Noir is often used for its structure and richness. Grown mainly in the Montagne de Reims region, it lends Champagne its red fruit notes and complexity. This grape is also prized for its ability to add depth and body to the wine.
Pinot Meunier is known for its roundness and freshness. It is mainly grown in the Marne Valley. This variety brings fruity and floral aromas, contributing to the overall balance of Champagne. It is often used in blends 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 region, it offers notes of white flowers, citrus and, at times, minerality. Chardonnay is essential for Champagnes of great purity and longevity.
The art of champagne-making lies in the judicious selection and blending of these grape varieties, creating perfect harmony and a unique flavour profile.
Harvesting: the first key stage
The harvest is one of the most crucial stages in the champagne-making process. It marks the beginning of the process of transforming grapes into wine. In Champagne, harvesting is generally done by hand, a tradition that preserves the integrity of the bunches and allows us to select only the best quality grapes.
The timing of the harvest is essential to ensure the grapes reach optimum ripeness. Winegrowers closely monitor the sugar content and acidity of the grapes to determine the ideal moment for harvesting. This is crucial, as it influences the final quality of the champagne. Over-ripe or under-ripe grapes can have a significant impact on the taste and balance of the wine.
During the harvest, the atmosphere is often joyful and collaborative. It is a time of celebration for the winemakers and their teams, as it marks the start of a new production season. It is also a time of intense, meticulous work, when each bunch 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 champagne-making process, 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 develops its initial aromas and basic structure.
Following 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 milder lactic acid. This process contributes to the aromatic complexity and balance of Champagne.
Mastery of these fermentation processes is essential to the development of Champagne’s flavour characteristics. Every choice and adjustment made by the winemaker during these stages has a direct impact on the wine’s final profile. It is a delicate balance of science and art that few wine regions master as well as Champagne.
Blending: the art of mixing cuvées
Blending is a key stage in Champagne production, where the winemaker’s art truly comes into its own. It involves blending wines from different cuvées, vintages and grape varieties to create a balanced, harmonious final product. This stage is often compared to composing a symphony, where each note must blend perfectly into 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 complexity. The winemaker’s expertise is evident in their ability to predict how the wines will evolve together and 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 years of experience and a refined palate. Blending is truly the soul of champagne-making, transforming the diversity of base wines into a sparkling work of art.
Malolactic fermentation: an essential stage
Malolactic fermentation is an optional but crucial stage in champagne production, influencing the drink’s taste and texture. This process involves converting malic acid, which is naturally present in the wine, into 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 softer and rounder on the palate. This is particularly important in cold regions such as Champagne, where grapes can naturally be more acidic. By lowering acidity, this fermentation contributes to Champagne’s overall balance and sensory profile.
As well as softening the wine, malolactic fermentation adds further aromas and flavours, such as buttery and creamy notes. These characteristics are particularly appreciated in certain styles of Champagne, where richness and complexity are sought after. Whether or not to carry out malolactic fermentation is therefore a strategic decision, depending on the style of Champagne the winemaker wishes to produce.
Creating the foam: the secret of the bubbles
The ‘prise de mousse’ is the magical stage in the champagne-making process, when the characteristic bubbles are formed. This process, also known as secondary fermentation, takes place in the bottle and is crucial to the development of champagne.
To initiate the formation of bubbles, a liqueur de tirage, made up of sugar and yeast, is added to the still wine. The bottle is then sealed with a temporary capsule. The yeasts consume the sugar and produce carbon dioxide, creating the fine, persistent bubbles for which Champagne is renowned. This process generally lasts from several weeks to several months.
This 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 champagne’s complex aromas and creamy texture. The longer the wine remains on its lees, the greater its depth and richness. This stage is a perfect example of the patience and expertise required to make Champagne, transforming the drink into a unique sensory experience.
Ageing: maturation and development of aromas
Champagne ageing is a crucial stage in the development of aromas and the maturation of flavours. After the second fermentation, bottles are stored in cool, dark cellars, often for several years, to achieve optimum complexity and finesse.
During ageing, champagne rests on its lees, contributing to the enrichment of its aromas and an improved texture. Aromas evolve from fruity and floral notes to more complex hints of toast, nuts and honey. The duration of the ageing process depends on the style of champagne, with some wines ageing for more than ten years.
Ageing on the lees is enhanced by the riddling process, in which bottles are regularly turned and tilted so that the lees gradually settle in the neck of the bottle. This step prepares the champagne for disgorging, allowing the deposits to be removed without affecting the wine’s clarity. 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 deposits 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 cork containing the sediment. This technique ensures that the champagne is crystal-clear and brilliant.
After disgorging comes the dosage stage, when liqueur d’expédition – a mixture of wine and sugar – is added to adjust the champagne’s final flavour. The dosage determines the champagne’s level of sweetness, 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 each bottle offers an unforgettable taste experience. It is the culmination of years of work and passion, resulting in a drink worthy of the greatest celebrations.

Today, champagne-making faces a number of contemporary challenges, prompting winemakers to innovate whilst preserving traditions. Among these challenges, climate change is one of the most pressing, affecting grape ripening cycles and harvest quality.
Fluctuations in temperature and unpredictable weather conditions are forcing growers to adapt their viticultural practices. Some are exploring new sustainable viticulture techniques to protect the vines and preserve the ecological balance. Research into more resilient grape varieties and experimentation with new growing methods are among the strategies being implemented to adapt to these changes.
In addition, 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.
