Into a cocktail shaker (or mason jar / make-shift shaker), squeeze fresh juice from half a grapefruit and half a lemon.
Add a handful of muddled mint leaves. If you don't have a muddled, rub the leaves together in your hands to help release the flavor.
Add wine, vodka, limoncello, and syrup. Shake well.
If you can find fresh passion fruit or fresh lychee, add.
Serve in a fancy glass and enjoy!
