Despite persistent internet claims, dangling a spoon in the neck of an open bottle of Champagne does absolutely nothing to preserve carbonation. A proper Champagne stopper costs a few dollars and actually works by creating a seal. Invest in one.
How to Store Champagne (Opened)
Reseal with a Champagne stopper or hinged bottle stopper immediately after pouring. The spoon-in-the-bottle trick does not work; it is a myth. Store upright in the refrigerator. The carbonation dissipates quickly once opened.
How to Tell if Champagne (Opened) Has Gone Bad
Look for these signs that champagne (opened) has spoiled: flat (lost all carbonation), vinegar smell, brownish color, unpleasant sharp taste
The Professor's rule: When in doubt, throw it out. No meal is worth food poisoning.
The Bottom Line
Properly stored champagne (opened) stays safe for 1–3 days in the fridge. Always store in airtight containers, refrigerate within 2 hours of purchase or preparation, and trust your senses. If something looks, smells, or feels off, discard it regardless of how many days it has been.
