How Long Does Champagne Last? A Complete Guide to Shelf Life & Ageing

There's a certain thrill in discovering a forgotten bottle of Champagne tucked away in a cupboard or gifted years ago. But before you pop the cork, one question inevitably surfaces: is this Champagne still good to drink?

Unfortunately, the answer isn't as straightforward as checking a best-before date, and understanding how long Champagne lasts depends on several factors – from whether it's vintage or non-vintage to how it's been stored.

At Sip, we are often asked about cellaring Champagne, so we thought it was high time we took a look at this popular topic.

How Long Does Unopened Champagne Last?

The shelf life of an unopened bottle varies significantly based on style:

Non-Vintage Champagne: 3-4 Years

Most non-vintage (NV) Champagnes are designed to be enjoyed within a few years of purchase. These wines are blended for immediate pleasure, crafted to deliver consistent style without requiring further ageing.

That said, many grower Champagnes are made with more complexity than their grande marque counterparts and some NV cuvées may evolve beautifully for five years or more. A good rule of thumb is take a look at how long the wine has spent 'on lees' as the lees (dead yeast cells) act as a protective barrier against oxidation, preserving the wine's freshness, while also allowing it to mature slowly.

Vintage Champagne: 5-10+ Years

Vintage Champagnes – made entirely from grapes harvested in a single exceptional year – are built for longevity. These wines typically have more structure, complexity, and ageing potential.

A well-stored vintage Champagne can easily last a decade, with prestige cuvées from exceptional years holding their quality for 20 years or longer. The key is patience and proper storage. 

Prestige Cuvées: 10-25+ Years

The finest prestige cuvées from grower producers can rival (and often surpass) the ageing potential of famous grandes marques. These are wines for collectors and special occasions, rewarding those who wait with extraordinary complexity. They will also often be singled out by producers for their ageing potential (so there is less guess work involved). For instance the limited edition 'Vinotheque' range by Caillez Lemaire were specifically held on lees for 10+ years before initial release.

How Long Does Champagne Last After Opening?

Once you've popped the cork, the clock starts ticking more urgently:

With a Champagne Stopper: Up to a week

A quality Champagne stopper can preserve your bubbles for a few days with no issue and, if the bottle is fairly full and kept still and refrigerated, in our experience they will usually retain freshness for up to a week. The key to success is minimising air exposure – seal the bottle immediately after pouring if you know you wont be finishing it in one sitting.

Without a Stopper: 4-6 Hours

Without a proper seal, Champagne loses its effervescence within hours. In the initial hour or two you will likely see the wine improve as it warms and opens, but after a few more hours it will become increasingly flat. Some people enjoy still Champagne (it's called 'Champagne tranquille'), but this transforms the experience entirely.

The Silver Spoon Myth

You may have heard that placing a silver spoon in the bottle neck preserves bubbles. Unfortunately, this is pure myth – scientific studies have thoroughly debunked it. Invest in a proper stopper instead.

What Affects Champagne Shelf Life?

Several factors determine how well your Champagne ages:

Storage Conditions

Temperature stability matters most. Champagne should be stored at roughly 10-12°C (50-54°F) in darkness, humidity and away from vibration. This is the reason that 100 bottles of 19th-century Champagne discovered in a shipwreck at the bottom of the Baltic Sea were perfectly preserved – it's near optimum conditions for Champagne storage (although not very practical!) – and some producers have gone so far as to sink their bottles in the channel for better ageing...

Bottle Size

Larger formats age more gracefully. Magnums (1.5L) are considered ideal for long-term ageing because the ratio of wine to air in the bottle neck is more favourable (double the amount of liquid to air compared to 75cl), whilst for half-bottles it is the opposite and they should, therefore, be consumed sooner.

Dosage Level

Dosage – the sugar added before final corking – affects ageing. Historically, higher dosage wines (Brut and above) have been considered better for long-term ageing because the sugar helps to balance high acidity and aids in the development of complex, toasty, and caramel-like notes. However, low dosage (Extra Brut or Brut Nature) wines can also age beautifully. The key is that the wine is well made, with high quality fruit and appropriate dosage to balance the cuvée. Without these elements, low or no dosage wines can become overly dry, acidic, or oxidise too quickly.

Production Quality

Grower Champagnes, with their attention to vineyard expression and minimal intervention, often age more interestingly than mass-produced alternatives. The wine's personality develops rather than simply fading over the years.

Signs Your Champagne Has Gone Bad

How do you know if a bottle has passed its prime? Watch for these indicators:

• Flat or diminished bubbles – Some loss of effervescence is natural with age and, indeed, very old Champagne (40+ years) can be nearly flat, but a complete flatness suggests the seal has failed

• Deep amber colour – Slight gold development is normal; dark amber or brown indicates over-oxidation

• Off aromas – Musty, vinegar-like, or cardboard notes suggest the wine has turned

• Cork damage – A dried, crumbly, or leaking cork often means compromised contents

When in doubt, open the bottle. Champagne that's past its peak but not spoiled is still perfectly safe to drink – it simply won't deliver the experience it once promised.

Does Champagne Improve With Age?

This is where high quality Champagnes truly shine. While most mass-produced Champagnes are made for immediate consumption, artisan bottles from small producers often reward patience.

Aged Champagne develops:

• Deeper complexity – Primary fruit gives way to secondary notes of brioche, honey, and toasted notes

• Creamier texture – The mousse becomes finer and more integrated

• Savoury character – Umami notes emerge, making aged Champagne magnificent with food

• With further ageing styill, secondary flavours make way for tertiary notes of mushrooms, truffle and forest floor (although this profile is not for everyone!)

The grower Champagnes in our Vintage Exploration Case offer an excellent introduction to aged Champagne's pleasures.

Frequently Asked Questions

Does Champagne go bad if not refrigerated?

Champagne won't immediately spoil at room temperature, but long-term storage in warm conditions accelerates ageing and can damage the wine. For best results, store at consistent, cool temperatures. Refrigerate before serving, not for long-term storage.

Can you drink 10-year-old Champagne?

Absolutely – if it's been well-stored. Vintage Champagnes and prestige cuvées are designed for this kind of ageing. Non-vintage Champagne may have lost some vibrancy but can still be enjoyable.

How long does Champagne last in the fridge?

Unopened, Champagne can stay in the fridge for several months, though it's not ideal for long-term storage (too cold, potential vibration). Opened with a stopper, expect at least 1-3 days.

Is it safe to drink old Champagne?

Yes – old Champagne won't make you ill. At worst, it may taste flat, oxidised, or unpleasant, but it's safe to consume.

The Bottom Line

How long Champagne lasts depends on the wine itself and how you store it. Non-vintage grower Champagnes offer three to five years of drinking pleasure; vintage bottles can reward patience for a decade or more. Once opened, enjoy within a few days – preferably sooner.

The best approach? Buy Champagne you're excited to drink, store it properly, and don't save it so long that the occasion never arrives. Great Champagne is made to be shared and enjoyed.
