Sangria - the classic Spanish cooler

Wash the fruits thoroughly, dry them, and place them in the refrigerator to chill well.

Slice the lemon and orange thinly, then place them in a large glass pitcher. Halve the apple, remove the core, slice it thinly, and add it to the pitcher as well. Sprinkle with cane sugar and pour in the rum. Let it mature in the refrigerator for at least 2 hours.

Gently press the fruits in the pitcher with a wooden spoon to release their flavors. Pour in the red wine, orange juice, and sparkling mineral water. Mix thoroughly, then add plenty of ice cubes.
