How to store an open bottle of Champagne? 5 essential tips
Why does opened Champagne lose its quality so quickly?
Wine oxidation
As soon as it is opened, Champagne comes into contact with the air. This causes oxidation, which alters its flavour and reduces its freshness.
Loss of bubbles and pressure
Champagne loses its fizz as the carbon dioxide escapes. This is why the wine quickly becomes ‘flat’.
The effect of temperature
Champagne left at room temperature loses its liveliness more quickly than a bottle kept chilled.
How long can you keep Champagne open?
With a special Champagne stopper
Up to 48 hours in the fridge, whilst retaining its fizz.
With the original cork
Storage is limited to just 12 to 24 hours, as the cork does not provide an airtight seal.
Without a stopper or any protection
The Champagne goes flat in just a few hours.
The best ways to store an opened bottle of Champagne
Use a special airtight stopper designed for sparkling wines
This is the most effective method: this type of stopper maintains the pressure and preserves the bubbles.
Put the bottle in the fridge
The cold slows down the evaporation of carbon dioxide.
Keep the bottle upright
When standing upright, the surface area in contact with the air is reduced, which limits oxidation.
Alternative tips if you don’t have a special stopper
Use a small silver spoon (myth or fact?)
This tip is very common, but tests show that it has no real effect.
Cover the neck of the bottle with cling film
This limits the amount of air entering the bottle, although it is less effective than a proper stopper.
Transfer to a small bottle
Less air = better preservation. Handy if you have a suitable container.
Mistakes to avoid at all costs
• Never leave the bottle open and unprotected.
• Avoid storing at room temperature.
• Do not store an opened bottle lying on its side.
What to do with a flat bottle of Champagne?
Use it in cooking
Flat Champagne can be used in sauces, risottos or stews.
Use it in cocktails
Add it to fruit juices or liqueurs to create original Champagne-based cocktails.
Waste-reduction tip
It can also be used to poach fruit or deglaze meat.
How long does an opened bottle of Champagne keep in the fridge?
With a suitable stopper: about 2 days. Without a stopper: just a few hours.
Can you drink Champagne without bubbles?
Yes, it’s not harmful, but it will have lost its charm and liveliness.
Does the spoon stopper really work?
No, it’s an urban myth with no scientific basis.
Should you put the metal cap back on?
No, it doesn’t maintain the pressure. Only an airtight stopper is effective.
Can opened Champagne be dangerous?
No, it doesn’t become toxic, but it loses its flavour.
Conclusion: store opened Champagne properly to keep the party going
The best way to store an opened bottle of Champagne is to reseal it with a special airtight stopper and keep the bottle upright in the fridge. This will preserve the bubbles and aromas for up to 48 hours.
👉 But remember: Champagne is a celebratory drink, meant to be enjoyed quickly and shared.
