Step 1Puree the raspberries, blackberries and simple syrup in a blender. Pour the puree into a glass bowl.
Step 2Crush the torn basil and mint leaves with your hands and stir into the pureed berries in the bowl. Cover and let stand 2 to 3 hours for the flavors to meld.
Step 3Strain the berries, pressing on the solids to extract all of the juices, and pour the strained syrup into a tall pitcher. Add the bottle of chilled wine. Stir in the Cinzano.
Step 4Top it off with a bottle of club soda and stir in lime slices, 6 raspberries and 6 blackberries and ice cubes just before serving.
