For Simple Syrup: Place all of the ingredients in a small saucepan and bring to a boil. Turn down to a simmer and cook uncovered for 20 minutes, stirring occasionally, until the fruit is totally collapsed. Pour the mixture into a fine mesh strainer, or a regular strainer lined with a cheesecloth, and gather the syrup into a bowl or jar. Put it into the refrigerator to chill, then put the fruit puree into a sealed container and save for breakfast!
For Fizz: Pour the sparkling wine into your champagne flute, add the simple syrup, and brandy, if using, and then give it a very gentle stir to combine. Celebrate!
