This recipe is best at the height of summer, when berries like raspberries, blueberries, strawberries, blackberries or gooseberries are at their peak. The alcohol in the wine and orange liqueur quickly and efficiently draw out the flavor of the vanilla and the lemon balm in the syrup.
Halve vanilla bean lengthwise and remove seeds with a small knife.
Place seeds in a bowl with remaining ingredients, except the fruit.
Stir, then cover with plastic wrap and let rest a few hours.
Clean fruit and gently stir into the wine infusion.
Refrigerate 45 minutes. Remove fruit from fridge a few minutes before serving.
