I've only had Sangria once...maybe they didn't make it right 
Probably not 
It's supposed to be made with rum. A lot of people add white soda. That's not Sangria. Kinda sweet, but refreshing on a hot, summer day. * 1/2 cup white sugar 1/2 cup white sugar

1. Have the fruit, rum, wine, and orange juice well chilled. Slice the lemon, lime and orange into thin rounds and place in a large glass pitcher. Pour in the rum and sugar. Chill in refrigerator for 2 hours to develop the flavors.
2. When ready to serve, crush the fruit lightly with a wooden spoon and stir in the wine and orange juice. Adjust sweetness to taste.
