Unlike a common misconception, Champagne is not made solely to be enjoyed immediately: vintage cuvées and Champagnes from great terroirs can gain complexity over several years when stored in the right conditions, ideally at 10–12°C and away from light. Non-vintage Brut Champagnes, on the other hand, are generally designed to be enjoyed when they are released from the cellars.
While Champagne is renowned for its brilliance, delicate effervescence and freshness, behind this youthful character lies a long and precise winemaking process, as well as a fascinating capacity for ageing. Although Champagne is often seen as a wine to be enjoyed without delay, certain cuvées are capable of evolving over many years, gradually revealing a new personality.
Like fine wines, Champagne continues its journey long after bottling. Slowly, in the cool darkness of the cellars, the bubbles become more refined, the aromas evolve and the personality of the cuvée takes shape before it is finally enjoyed.
This raises an important question: how long can Champagne be kept, and how should it be stored?
Are All Champagnes Equal When It Comes to Ageing?
First of all, it is important to understand that, unlike in some other wine regions, Champagne has a minimum ageing period that must be respected before bottles can be released for sale: a minimum of 15 months for non-vintage cuvées and 36 months for vintage Champagnes. This legal requirement ensures sufficient ageing time and allows the wine to develop its aromas.
In practice, ageing periods are often considerably longer: generally between 2 and 3 years for non-vintage cuvées and between 4 and 10 years for vintage Champagnes. This reflects the patience and precision involved in crafting each cuvée.
At Canard-Duchêne, all our Champagnes are aged for a minimum of 2 years in our cellars, with at least 3 years for our Iconic cuvées, and at least 6 years for our vintage Champagnes.
Not all cuvées are designed and crafted to respond to the passage of time in the same way:
Non-vintage Brut Champagnes (NV) are generally created to express freshness, fruit and vibrancy. They are therefore intended to be enjoyed relatively soon after the ageing period defined by the Maison or grower. However, they can still be kept for several additional years without losing their personality, provided they are stored in suitable conditions.
Champagnes from great terroirs or outstanding vintages, meanwhile, are often made from carefully selected grapes with greater structure and more pronounced ageing potential.
The choice of blend can also influence a Champagne's ageing capacity. Chardonnay brings tension, finesse and consistency, giving the wine strong ageing potential, while Pinot Noir, with its depth and structure, gradually reveals its full expression over time. Whether used individually or together, these grape varieties can therefore give Champagne excellent ageing potential.
How Does Time Transform the Aromas of Champagne?
One of the most fascinating aspects of ageing in the cellar is the transformation of a wine's aromatic profile. Over the months and years, Champagne gradually moves away from its most youthful aromas to reveal a more complex and nuanced expression.
Depending on the blend, citrus, fresh fruit and white flower notes gradually give way to dried fruit, honey, brioche and pastry aromas, sometimes accompanied by notes of forest floor and truffle. This natural evolution enriches the wine without erasing its original identity or the freshness that characterises Champagne.
On the palate, the effervescence often becomes more delicate, the texture silkier and the expression deeper, creating a particularly harmonious experience sought after by lovers of great Champagne wines.
At Champagne Canard-Duchêne, this expression of time can be experienced in our prestige V2012 cuvée. After ten years of ageing in the cellars, it reveals a richly layered aromatic profile, where depth, finesse and complexity come together with elegance. On the nose, this Champagne offers brioche and toasted notes alongside aromas of ripe fruit. On the palate, ageing has brought out cedar wood notes, a saline touch and a hint of grapefruit, balanced by intense freshness and a long, delicate finish. It is a tangible illustration of the way time can reveal the full dimension of a great Champagne.

What Factors Influence the Ageing of Champagne?
While time plays a central role in Champagne maturation, it is never the only factor. Several elements determine a cuvée's ability to evolve favourably over the years.
The wine's style is key: the blend, grape varieties, acidity and overall balance all directly influence its ageing potential. Cuvées with good acidity and harmonious structure generally have a greater capacity for ageing. Acidity acts as a natural preservative, helping to preserve freshness and aromas while limiting oxidation over time.
The choice of dosage also plays a role. Low-dosage Champagnes, such as Extra Brut and Brut Nature, often reveal greater aromatic purity, which can support their ageing and development over time.

The winemaking method can also influence a Champagne's ageing potential. Careful management of both alcoholic and malolactic fermentation helps shape the wine's style and preserve its acidity.
Storage conditions are equally important. A stable temperature, controlled humidity and protection from light allow Champagne to continue evolving under the best possible conditions.
Finally, the length of time spent ageing on the lees before disgorgement contributes significantly to the wine's future richness. Prolonged contact with the yeast encourages the development of aromatic complexity, one of the defining characteristics of great Champagne wines.
How Should You Store a Bottle of Champagne?
Every bottle of Champagne deserves to be stored in suitable conditions to allow it to express its full potential over time without compromising its personality.
Ideally, bottles should be stored in a cool, dark place at a constant temperature, preferably between 10 and 12°C. This stability allows the wine to evolve slowly and harmoniously. Sudden temperature fluctuations should be avoided, as they can accelerate the wine's evolution and disturb its balance. Direct light should also be avoided, as it can affect the aromatic qualities of Champagne. Whenever possible, bottles should be stored horizontally to help keep the cork moist and maintain a good seal.
These are the same conditions found in the historic cellars of Canard-Duchêne, carved into the chalk in the 19th century. All the Maison's Champagnes are aged in this natural environment, in the heart of the Montagne de Reims terroir.

When Does Champagne Reach Its Peak?
Every Champagne has its own rhythm. Like a great wine, it goes through different stages before reaching what is known as its peak maturity. This is the moment when freshness, aromatic complexity and texture reach their ideal balance. The wine fully expresses its character, offering a harmonious and complete tasting experience.
In general, Champagne Houses and growers choose to release their cuvées when they have reached their ideal drinking window.
For a non-vintage Champagne, you can then keep the bottle for three to five years before enjoying it, provided it is stored under suitable conditions.
Vintage Champagnes, meanwhile, can sometimes continue to evolve for up to ten years, provided they are kept away from light at a stable temperature between 10°C and 12°C.
How Should You Taste an Aged Champagne?
Tasting a mature Champagne invites you to slow down and pay particular attention to its finer details.
Unlike younger cuvées, it is recommended to serve mature Champagne slightly warmer, at 10–12°C rather than the usual 8–10°C, allowing its full aromatic expression to emerge. Serving temperature acts as a true sensory revealer, helping to bring out the wine's complexity and depth.
The bottle should be opened gently in order to preserve the finesse of the effervescence. Once in the glass, the wine gradually reveals its most subtle nuances, gaining depth as it opens up and offering a tasting experience that unfolds in several stages.
At the table, mature Champagnes can be enjoyed much like great still wines, naturally pairing with refined dishes such as white meats, fine fish, truffle-based dishes, mature cheeses and gastronomic creations.

How Can You Tell If a Champagne Is Past Its Best?
A bottle that has been poorly stored or has exceeded its ageing potential will often show several tell-tale signs: weakened effervescence when opened, less precise aromas and a gradual loss of freshness. Pronounced oxidative notes may also appear, disrupting the wine's balance.
By contrast, a well-stored Champagne will retain its vitality while developing a more complex aromatic profile. Notes of dried fruit, brioche, honey and candied fruit are generally signs of successful ageing.
Ultimately, it is not simply the length of time a bottle has been stored that determines the quality of its evolution, but above all the conditions in which it has been kept.
