Start with a bottle of red wine, not too expensive, not too cheap. Or use some leftover wine... Preferably a full bodied red wine.
1 lemon cut in wedges
1 orange cut in wedges
Pour wine in pitcher. Squeeze out the juice in the wine and toss the wedges in the pitcher. Add some sugar or honey according to taste.
Cool the mixture in a fridge for at least a couple of hours or overnight.
Just before serving add ice cubes and (optional) some carbonated soda.
Add apple, peach, berries, pineapple, melon, grape, or mango to make it less of a drink and more of a fruit punch..
Sangria blanca: use Sauvignon Blanc instead of red wine.
Zurra: sangria made with peaches and nectarines. Add some lemon zest and cinnamon.
