Classical Spanish Sangria-always cool and slightly curl the head)

A classic recipe for a famous drink. In principle, you can add any fruit, but apples or pears absorb all the rum. In classic sangria do not add lemonade or other carbonated drinks.
1 lemon
1 lime
1 orange
1½ cups of rum
½ cup sugar
1 bottle (750 ml) of dry red wine
1 glass of orange juice
Fruits, rum, wine and orange juice should be cold. Slice the lemon, lime and orange with thin slices and put in a large glass jug. Add rum and sugar. Put in the fridge for 2 hours, so that the mixture is infused.
Before serving, remember the fruit with a wooden spoon and mix the wine and orange juice. Add sugar to taste.
