Champagne should typically be stored in a cool, dark area standing upright. However, for long-term storage, it is best stored on its side to prevent the cork from drying out and oxidising. The ideal temperature for champagne storage is between 8-10°C (47-50°F). If you live in a humid place like Hong Kong, it’s important to keep humidity levels low because high humidity can cause damp corks and risk ruining the champagne over time. Lastly, make sure your bottles are stored out of direct sunlight as this can heat up your bottles and age them prematurely.
