Sangria is a wine punch typical of Spain.  You start with a cheaper red table wine and can play with the other ingredients such as the fruit juices or carbonation using ginger ale, Sprite or club soda.  Here is a great recipe  to use as a guideline:

Ingredients
1/2 cup brandy
1/4 cup lemon juice
1/3 cup frozen lemonade concentrate
1/3 cup orange juice
1  bottle dry red wine
1/2 cup triple sec
1 lemon, sliced into rounds
1 orange, sliced into rounds
1 lime, sliced into rounds
2 cups club soda, sprite or ginger ale. (optional)
8 STAR maraschino cherries

DIRECTIONS:
1. In a large pitcher or bowl, mix together the brandy, lemon juice, lemonade
concentrate, orange juice, red wine, and triple sec. Float slices of lemon,
orange and lime, and maraschino cherries in the mixture. Refrigerate overnight for
best flavor. For a carbonated sangria, add club soda, sprite or ginger ale just before serving

Sit back and enjoy!
