How to store unopened champagne?
Quick answer
Store champagne on its side in a cool (10-12 °C), dark, vibration-free spot with around 70% humidity. Non-vintage champagne is best enjoyed within 3-5 years of purchase. Vintage or prestige cuvées can age 10-20 years if stored properly. Don't keep champagne in the fridge long-term — the vibrations and dry air will do more harm than good.
Detailed answer
Many people store champagne in the fridge for months — and it's one of the most common wine storage mistakes. Your fridge is too cold (3-5 °C), too dry, and the compressor vibrates constantly. Fine for chilling a bottle overnight before a party, terrible for long-term storage.
The ideal conditions are the same as for any fine wine: steady temperature around 10-12 °C, 70% humidity, darkness, and no vibration. A proper wine cellar or a good wine fridge (not your kitchen fridge) is perfect.
Store champagne bottles on their side. While the internal pressure (5-6 atmospheres) does keep the cork moist from the gas side, having the wine touch the cork gives extra protection against drying.
Light is champagne's worst enemy. UV rays cause 'light-strike,' giving the wine unpleasant wet-wool or cabbage aromas. This happens faster with clear glass bottles (some rosé champagnes use them), so keep all champagne in the dark.
How long can you keep it? Non-vintage (NV) champagne — the standard offering from most houses — is blended to be ready on release. It's at its best within 3-5 years of purchase. It won't go bad after that, but the bubbles soften and the freshness fades.
Vintage champagne is a different story. Made only in exceptional years, it has the structure and complexity to age 10-20 years, developing gorgeous toasty, nutty, and honeyed notes. Prestige cuvées (think Dom Pérignon, Krug, Cristal) can be stunning at 15-25 years old.
Pro tip: when you're ready to drink, chill the bottle in the fridge for 3-4 hours (or 20 minutes in an ice bucket with water). Serve at 8-10 °C in a white wine glass — not a coupe — to appreciate the aromas and the fine bead of bubbles.
