How do I store Dom Perignon?
While the temperature inside a typical fridge is not ideal, it is suitable for short-term storage to chill the Dom Perignon before drinking. Dom Perignon is most-affected by light and when possible, it should be put in a cellar where it is completely dark. To chill before serving, place the entire bottle in a bucket of ice for about 15 minutes until chilled. Source: domperignon.com
