Most champagne is meant to be enjoyed within months of purchase. But the best bottles, the ones worth your attention and investment, can age beautifully for decades, developing complexity and nuance that young champagne cannot touch.
Understanding which champagnes improve with age, how to store them properly, and when to open them is the difference between drinking a bottle at its peak and drinking it past its prime, or worse, opening it too early and missing the magic entirely.
At The Champagne Fox, we work with growers who make champagnes built to age. This guide will teach you how to approach aging, which bottles to cellar, and how to know when a champagne is ready to drink.
Non-Vintage Champagne: Fresh and Ready
Most champagne sold is non-vintage (NV). This means the wine is a blend of multiple vintages, typically combining reserve wines from several harvests with younger wine from the current year.
Non-vintage champagne is designed for immediate drinking. When you buy a bottle, it is usually ready to open right then. The blending is precisely done to create a balanced, approachable wine that does not need time.
Storage Duration
Non-vintage champagne will keep for 3-5 years in proper storage conditions (cool, dark, on its side). It does not improve with age. It can become slightly more complex after a year or two, but this is marginal. It deteriorates after about 5 years.
When to Open
Open non-vintage champagne within 1-2 years of purchase, ideally within the first year. You are not aging it; you are simply enjoying it.
Vintage Champagne: Built to Age
Vintage champagne is made in exceptional years when the harvest is so good that the producer decides to bottle a vintage champagne. This happens perhaps 3-4 years per decade in Champagne.
A vintage champagne contains grapes from a single year, making it a snapshot of that specific vintage. Every bottle reflects the weather, the sunshine, the rainfall, the decisions made by the grower that year.
Vintage champagnes are built to age. The aging process in bottle, contact with the lees, and development over time create complexity that young champagne does not have.
Which Vintages Are Worth Aging
Not all vintage years are equal. Some produce lighter, more delicate wines that are best drunk younger. Others produce powerful, structured champagnes that improve for decades.
Generally, older vintages with more concentration and fuller body age better than light, delicate ones. A 2012 from a cold year will be lighter than a 2008 from a warmer year.
Ask your producer or our team about the aging potential of a specific vintage. They know how the year played out and can advise whether a bottle is built for immediate drinking or long-term aging.
Storage Duration
Vintage champagne will keep beautifully for 10-20+ years in proper storage. Some exceptional bottles from great years can age 30+ years. The older it gets, the more likely the cork begins to deteriorate, but many well-made vintage champagnes drink beautifully at 20 years old.
When to Open
This depends on the vintage and your preference:
Young vintage (0-5 years old): Still relatively fresh, with primary fruit notes. Enjoyable now, but will improve.
Mature vintage (5-15 years old): In the sweet spot. Primary fruit has mellowed into secondary notes of brioche, toast, dried fruit, minerals. Complexity has developed. This is usually when a vintage champagne is at its most interesting.
Aged vintage (15+ years old): The wine is developing tertiary notes. Colour is deepening. The wine becomes more delicate, sometimes more austere. Beautiful if you enjoy aged champagne, but no longer fruit-forward.
If you are unsure when to open a vintage, ask us. We know when bottles peak.
Prestige Cuvées: The Ultimate Aged Champagnes
Prestige cuvées are the flagship bottles from a producer, typically made from their best vineyards in exceptional years. They are the most expensive, most exclusive, and absolutely built to age.
Dom Pérignon, Krug Clos d'Ambonnay, and similar big-house prestige cuvées are designed for 15-30 years of aging. Prestige cuvées from grower producers similarly develop beautifully over time.
These are bottles worth holding. A prestige cuvée at 15 years old tastes nothing like it did at 5 years old. The development is remarkable.
How Champagne Develops With Age
The First 3-5 Years
Immediately after release, a champagne (especially a vintage or prestige cuvée) is still showing primary fruit: citrus notes, green apple, stone fruit. The champagne is vibrant, fresh, youthful.
The cork takes a few months to settle. After 3-5 months, the champagne has mellowed slightly as the new-wine notes settle. This is when it becomes very enjoyable to drink.
5-10 Years
Primary fruit notes begin shifting into secondary notes. The wine develops brioche, toast, nuts, dried stone fruit. The minerality becomes more apparent. The champagne becomes more complex, less obviously fruity.
This is when many champagnes enter the sweet spot: still vibrant enough to have energy, complex enough to reward attention.
10-20 Years
The champagne continues deepening. Tertiary notes develop. Honey, caramel, leather, tobacco leaf, dried flowers. The wine becomes denser, more layered. The acidity softens slightly.
For someone who loves aged wines, this is peak. For someone who prefers fruit and freshness, the champagne may now be too developed.
20+ Years
The wine is now elderly. It still tastes like champagne, but it is fragile. The cork may be deteriorating. The fizz may be diminishing. The colour is gold or deeper.
If the storage was impeccable and the bottle is well-sealed, the champagne can be beautiful. But it is at risk. This is when you open a bottle not to age further, but to finish it.
Storage: The Foundation of Aging
Proper storage is absolutely essential. Improper storage will ruin a champagne in months, no matter how good it is.
The Ideal Environment
Temperature: Between 10-13 degrees Celsius is ideal. Consistency matters more than the exact number. Temperature fluctuations age champagne prematurely. A cool cellar at steady 10-13°C is perfect. A room that swings from 5°C to 20°C is harmful.
Darkness: Keep champagne away from sunlight and bright artificial light. UV light degrades wine. A dark cellar or covered wine cabinet is ideal.
Position: Store on its side. The cork must be in contact with the wine. If stored upright, the cork dries out, shrinks, and allows air inside. Over time, the champagne oxidizes.
Humidity: Some humidity is helpful to prevent cork deterioration, but excessive moisture ruins labels. 50-70% relative humidity is ideal. A wine fridge typically maintains this.
Stillness: Keep bottles away from vibrations. Constant movement and vibration accelerate aging. A quiet cellar is better than a living room near speakers.
Storage Solutions
A wine cellar: If you have a basement or spare room, maintain it at 10-13°C and 50-70% humidity. Install minimal lighting. Store bottles on their side. This is the gold standard.
A wine fridge: A dedicated wine refrigerator is expensive but reliable. You control the temperature precisely, it maintains humidity, it is dark, it is stable. For serious collectors, this is the practical choice.
A cool closet: A closet away from windows, away from heat sources, away from direct sunlight can work if it stays cool enough. Not ideal, but acceptable.
Under the stairs: Traditionally used, but temperature stability can be an issue.
A wine storage service: Professional storage facilities maintain perfect conditions. You pay a yearly fee, but your bottles are absolutely safe. This is ideal if you do not have good storage at home.
When to Drink: The Gamble of Timing
Deciding when to open an aged champagne is part intuition, part science.
Signs a Champagne Is Ready
The nose opens. When you smell the bottle, does it smell open, complex, developed? Or does it smell young and primary?
The colour deepens. A champagne that has aged for 15 years should have deepened from pale gold to richer gold. If it is still pale, it is probably not ready.
The occasion justifies it. You do not need to wait for a monumental reason, but opening a 20-year-old champagne should feel intentional, not casual.
Signs to Open Now, Not Later
The cork is deteriorating. If you see signs of mould, discolouration, or cork creep (wine seeping from under the cork), the bottle may be compromised. Open it sooner rather than later.
The storage has been questionable. If you are unsure whether the champagne was stored properly, open it sooner. Better to drink it now than risk it being corked.
You cannot stop thinking about it. This is not a scientific measure, but if you keep wondering what it tastes like, open it. Life is short.
The Reality of Aging Champagne
Aging champagne is not an investment scheme or a financial speculation. It is a patient practice for people who love the wine and want to understand how it develops.
Most people drink non-vintage champagne fresh, for immediate pleasure. This is correct. Most champagne is designed for this.
But for the bottles worth aging, for the vintage champagnes and prestige cuvées, patience reveals layers of complexity that young wine cannot show. A 15-year-old champagne from an independent grower tastes like nothing the same champagne tasted like at 3 years old.
If you have a bottle worth aging, store it properly, mark the year, and open it years from now. You will understand why people age champagne.
Frequently Asked Questions
How can I tell if a champagne is built to age?
Vintage champagnes and prestige cuvées from exceptional years are built to age. Non-vintage champagne is not. Ask your producer or our team about a specific bottle.
Can I age champagne in a regular wine rack at room temperature?
No. Room temperature (18-20°C) is too warm and too variable. You need cool, consistent conditions.
What happens if champagne gets too warm while aging?
Exposure to warmth accelerates aging and oxidation. The champagne may develop prematurely, become flat, or turn to vinegar.
How do I know if an old bottle is still good?
Look at the wine level (cork creep indicates leakage), check for mould on the cork, smell for off odours. When in doubt, open it and taste.
Can I age champagne in a wine fridge on my kitchen counter?
If the fridge is away from direct sunlight and maintains steady temperature, yes. Just avoid opening the door frequently (this causes temperature fluctuations).
Is a 30-year-old champagne still drinkable?
Maybe. It depends on storage and the bottle's condition. Some 30-year-old champagnes are beautiful. Others are oxidized or corked. You cannot know until you open it.
Should I age champagne horizontally or at an angle?
Horizontal (lying on its side) is ideal. Angled is acceptable if horizontal is not possible. The key is cork contact with wine.
What is the point of aging champagne if I can just buy a newer vintage?
Aged champagne develops complexity you cannot get from young champagne. A 15-year-old bottle tastes fundamentally different (often better) than the same champagne at 3 years old.
