Combine all ingredients in a large pitcher, stirring until sugar is completely dissolved. Serve immediately, or if making in advance, refrigerate up to 24 hours, and then add the club soda just before serving.
Notes
You can add any combination of fruit you like, think blueberries, oranges, apple slices, berries, pineapple, grapes, melon, kiwi or even mango. Beforehand, place some extra fruit in the freezer. When ready to serve, put a few pieces of fruit into each glass.I recommend using a dry and acidic white wine like a Sauvignon Blanc or a Pinot Grigio. You still want to use a good quality wine for this recipe so the final result is balanced in flavour.
