Combine in a shaker with ice:

The juice of 1/2 orange
The juice of 1/2 lime
The juice of a lemon

half oz of brandy
sweet syrup to taste

Add a nice fruit-forward red wine (jammy cabernet blends work well)

Shake to chill, serve in a margarita glass with plain soda or ginger ale, garnish with orange and lemon slices plus berries and mint sprigs
