Pour the peach nectar or juice into the cup with the mulled mint. Make sure the peach nectar is well refrigerated. Let it sit for about 15 minutes absorbing the mint juices.
Strain the mint out of the peach juice. Pour one half of the peach juice in a champagne glass (you can also use a wine glass or a tall glass) and add champagne as desired. The best combination is one part champagne and one part mint peach juice.
Use a mint leaf and any fruit as garnish and enjoy!
