Sangria is known as the summer drink of choice in Spain and Portugal. This drink is a party favorite because it can be prepared up to 5 hours in advance—plenty of time to get everything ready and mingle with guests!
Stir together wine, apricot nectar, oranges and lemons in a pitcher. (This may be prepared up to 5 hours ahead; keep covered at room temperature.)
To serve, add plums and grapes, stir in seltzer, and pour sangria over ice in glasses.
