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.
