For long-term storage, champagne is best stored laying on its side in a cool, dark place with consistent temperature (ideally between 10–13 °C; max 15 °C) and humidity.  Do not store champagne in the refrigerator long term: the lack of humidity can cause the cork to dry out, potentially allowing the wine to oxidise, altering its flavour profile. Do not store champagne in natural sunlight or artificial light: this will heat the wine and cause it to become stale. Store champagne in an undisturbed space: frequent vibrations will agitate the wine and affect its flavour profile and ageing potential. For champagne bottles that are delivered in orange cellophane wrapping, do not remove this protective wrapping when storing. It is an anti-UV cellophane wrapping used to protect against lightstrike for clear glass bottles. If you are faced with the problem of not being able to finish a bottle, it can be kept fresh in the fridge for a day or two with a champagne stopper.
