1/4 cup sugar
2 750-milliliter bottles cabernet sauvignon (or other red wine of choice)
1 cup orange juice
1/4 cup orange liqueur such as Grand Marnier or Triple Sec
24 ounces club soda chilled
2 oranges, thinly sliced (plus additional for garnish)
1 cup fresh blackberries, plus additional for garnish
Bring sugar and 1 1/4 cups water to a boil in a saucepan over medium-high heat, stirring occasionally, until sugar is dissolved. Remove from heat, and let stand 10 minutes.
Combine sugar mixture, red wine, orange juice, and liqueur in a large container; cover and chill 4 hours. Stir in club soda, oranges, and blackberries just before serving. Serve over ice.
