Champagne is a sparkling wine associated with luxury, celebration, and tradition. Unlike regular wines, champagne undergoes a unique production process that gives it its distinct effervescence and flavor. In this article, we will explore the step-by-step process of how champagne is made, from harvesting grapes to the final bottling stage. Understanding this process can deepen appreciation for one of the world’s most beloved beverages.
1. Grape Selection and Harvesting
The first step in champagne production begins in the vineyard. Champagne is primarily made from three types of grapes: Chardonnay, Pinot Noir, and Pinot Meunier. These grapes thrive in the cool climate of the Champagne region in France, which is why true champagne can only be produced there.
The grapes used in champagne must be picked carefully and quickly to ensure they are at the perfect level of ripeness. The grape harvest, called vendange, typically takes place in September. Only hand-picking is allowed to prevent the grapes from being damaged, which could affect the quality of the wine.
2. Pressing the Grapes
Once the grapes are harvested, they are taken to the press house. Champagne production requires gentle pressing to ensure only the purest juice, known as cuvée, is extracted. The goal is to avoid any bitter compounds from the skins, seeds, and stems of the grapes, especially since two of the main grapes, Pinot Noir and Pinot Meunier, are red-skinned. The first pressing produces the highest quality juice, while subsequent pressings result in lesser-quality juice called taille.
3. Fermentation
The pressed grape juice, also called must, undergoes its first fermentation. This process usually takes place in stainless steel tanks, although some champagne producers use oak barrels for added complexity. During this stage, the natural sugars in the grape juice are converted into alcohol by the yeast.
This initial fermentation lasts a few weeks, and once complete, the resulting wine is called base wine. At this point, the wine is still flat and acidic, quite different from the sparkling champagne we know.

4. Blending (Assemblage)
One of the most critical steps in making champagne is the blending process, or assemblage. In this stage, winemakers blend base wines from different vineyards, grape varieties, and sometimes even different vintages to create a consistent and balanced final product. The skill of the winemaker is essential here, as they decide which combinations will result in the best flavor profile.
In the case of non-vintage champagne, wines from several years are blended to maintain a consistent house style. Vintage champagne, on the other hand, is made from grapes harvested in a single exceptional year.
5. Bottling and Secondary Fermentation
After blending, the wine is bottled with a mixture of yeast and sugar, known as the liqueur de tirage. The bottle is then sealed with a temporary cap, and the wine undergoes a second fermentation inside the bottle. This secondary fermentation is what gives champagne its bubbles. The yeast converts the sugar into alcohol and carbon dioxide, creating the sparkling characteristic.
This stage, called prise de mousse, lasts for several weeks or months. As the yeast consumes the sugar, it leaves behind tiny bubbles of carbon dioxide. The bottles are stored horizontally in cool, dark cellars during this period to allow the champagne to age and develop complexity.
6. Aging
Once the second fermentation is complete, the champagne is allowed to age on its lees (dead yeast cells). This process can last anywhere from 15 months for non-vintage champagne to three years or more for vintage champagne. The longer the champagne ages, the more complex its flavors become, with notes of toast, brioche, and nuttiness developing over time.
7. Riddling (Remuage)
After aging, the yeast cells need to be removed from the bottle. This is done through a process called riddling, or remuage in French. The bottles are placed on special racks, called pupitres, at a 45-degree angle. Over several weeks, the bottles are gently rotated and tilted so that the dead yeast cells settle in the neck of the bottle.
This task was traditionally done by hand, but modern champagne houses often use machines called gyropalettes to speed up the process.
8. Disgorging (Dégorgement)
Once the yeast sediment has collected in the neck of the bottle, it’s time for disgorging, or dégorgement. The neck of the bottle is dipped into a freezing solution, causing the yeast sediment to freeze into a solid plug. The bottle is then uncapped, and the pressure inside forces the frozen sediment out.
This step ensures that the champagne is clear and free of any leftover yeast particles, but it also causes a small amount of wine to be lost in the process.
9. Dosage and Corking
After disgorging, the bottle is topped off with a mixture of wine and sugar syrup, called liqueur d’expédition. The amount of sugar added at this stage determines the sweetness level of the champagne. For example, Brut champagne has little to no added sugar, while Demi-Sec champagne is sweeter.
The final cork is then inserted into the bottle, and a wire cage, known as a muselet, is placed over the cork to prevent it from popping out due to the pressure inside the bottle.
10. Labeling and Packaging
After corking, the champagne is ready for labeling and packaging. Champagne bottles are often adorned with elegant labels and foil wraps to highlight the luxury of the product. At this stage, the champagne is also given time to rest and recover from the disgorging process before it’s shipped out to consumers.
Sweetness Levels of Champagne
Champagne comes in various levels of sweetness, and the amount of sugar added during the dosage process determines this. Below are the common sweetness levels of champagne:
- Brut Nature (0-3 grams of sugar per liter)
- Extra Brut (0-6 grams of sugar per liter)
- Brut (0-12 grams of sugar per liter)
- Extra Dry (12-17 grams of sugar per liter)
- Sec (17-32 grams of sugar per liter)
- Demi-Sec (32-50 grams of sugar per liter)
- Doux (50+ grams of sugar per liter)
Champagne Production Regulations
Champagne production is governed by strict regulations set by the Appellation d’Origine Contrôlée (AOC) in France. To be labeled as champagne, the wine must meet specific criteria, such as being made in the Champagne region, using approved grape varieties, and following traditional production methods.
Conclusion
The process of making champagne is intricate and time-consuming, involving multiple steps from the vineyard to the bottle. Each stage is essential in crafting the perfect champagne, ensuring its quality, taste, and signature bubbles. Whether you prefer a Brut or Demi-Sec, the next time you raise a glass of champagne, you can appreciate the skill and tradition behind its creation. Cheers!
