Discover the Art of Champagne Disgorgement
Champagne production is a meticulous and time-honored process built around nine essential stages: harvesting, pressing, vinification, blending, bottling (tirage), aging, riddling, disgorgement, and dosage.
Among these stages, disgorgement represents the culmination of years of expertise, cellar work, and patient maturation. It marks the transition between lees aging and dosage—the final step that defines the Champagne’s ultimate expression and style.
What Is Champagne Disgorgement?
Disgorgement is the process of removing the natural sediment that has accumulated in the neck of the bottle during riddling.
During lees aging, yeast cells created during fermentation gradually settle inside the bottle. These deposits form after the second fermentation, when the wine develops its signature effervescence. To preserve the Champagne’s clarity, purity, and aromatic balance, these sediments must be removed with precision. This is the essential purpose of Champagne disgorgement.
Disgorgement is a decisive moment in the evolution of the wine, revealing its full character while preparing it for its final stage of production.
Disgorgement: A Key Stage in Champagne Production
By ending the prolonged contact between the wine and its lees, disgorgement signals the completion of cellar aging—a period during which the cuvée develops much of its aromatic complexity. It is also the first time, after many months or even years of maturation, that the wine is exposed to oxygen, contributing to the evolution of its balance and sensory profile.
It is during cellar aging that Champagne develops its distinctive aromas and complex notes of brioche, dried fruits, toasted nuts, and honey. By selecting a precise disgorgement date, Champagne houses can achieve the ideal balance between freshness and aromatic richness.
Depending on the desired style, some bottles may benefit from late disgorgement, intentionally extending cellar aging to enhance complexity, depth, and aromatic intensity.
To preserve the full potential of the wine, disgorgement must be carried out with exceptional care and expertise.
Ice Disgorgement vs. Manual Disgorgement: Modern and Traditional Methods.
There are two main methods of Champagne disgorgement:
- 1 - Ice Disgorgement (Disgorgement à la glace)
- 2 - Manual Disgorgement (Disgorgement à la volée)
Ice Disgorgement
Today, ice disgorgement is the most widely used method in Champagne production. The neck of the bottle is immersed in a refrigerated solution at approximately -25°C (-13°F). The sediment collected during riddling becomes trapped in a frozen plug formed inside the bottle neck.
When the bottle is opened, the natural internal pressure expels the frozen plug, ensuring the clean and precise removal of the lees while minimizing wine loss.
Manual Disgorgement
Now less common, manual disgorgement—known as disgorgement à la volée—is a traditional technique historically practiced by Champagne growers. This highly skilled method involves opening the bottle by hand without prior freezing. As the bottle is uncapped, the natural pressure forces the sediment out. The cellar master quickly covers the bottle opening with a finger to minimize wine loss. More demanding and artisanal, this technique is still reserved for certain prestige cuvées and large-format bottles, preserving the heritage of traditional Champagne craftsmanship.
After Disgorgement: Champagne Dosage
Following disgorgement, a small amount of wine is inevitably lost during the removal of the lees. The bottle is then topped up with the liqueur d’expédition, also known as the dosage liqueur.
Made from reserve wines and a carefully measured amount of sugar, this blend determines the final style of the Champagne—from the exceptionally dry Extra Brut to the richer and more indulgent Doux style.
This stage, known as dosage, is the final touch in Champagne production before corking and wirehooding the bottle.

How Can You Find the Disgorgement Date of a Champagne?
Some Champagne Houses indicate the disgorgement date on the back label of their bottles. While optional, this information helps wine enthusiasts better understand the history and evolution of a particular cuvée.
Especially valued for vintage Champagnes and prestige cuvées, the disgorgement date serves as a valuable reference point for assessing the duration of cellar aging and the wine’s stage of development.
At Champagne Canard-Duchêne, for example, this information is available for the vintage cuvée V2012.
