Combine the brandy, sugar and half of the raspberries in a medium saucepan over medium heat and cook, stirring, until the sugar dissolves, 2 to 3 minutes. Add the red wine, vinegar and cinnamon stick and cook until the wine reduces by half, 8 to 10 minutes. Transfer to a bowl set over a bowl of ice to chill it quickly. Once the wine is cool, stir in the coconut water, apples and tangerine slices. Discard the cinnamon stick. If too strong, add some cold water.
