In the bottom of a large pitcher, muddle the lemon slices with the flavored brandy until the lemons have released some juice. Add in the lemonade concentrate and white wine and chill for four hours.
Lightly stir in the Prosecco and serve over ice. Use some of the fruit from the pitcher for garnish.
Notes
Add extra sliced fruit like strawberries, peaches, blueberries, or mango to change the flavor profile.
