Combine your Sauvignon Blanc, liqueur and sugar in a large container. Juice one orange and add to wine mixture. Slice one medium-sized orange and one lemon, and add fruit rounds to mixture. Refrigerate 6-12 hours. When it's time to serve, pour fruit-infused mixture into a glass of your choice over ice. Top with club soda and enjoy! You can choose to garnish with fresh fruit or fruit from the mixture or not at all.
