Combine the diced peaches, the orange juice and the simple syrup in a blender and blend until smooth.
Add in the Metaxa and stir until well combined.
Place 4 - 5 ice cubes in a glass and pour the drink over the ice.
Garnish your glass with a slice of peach and serve immediately.
Enjoy!
Notes
We used 12 stars Metaxa for this drink, but you can use a different Metaxa if that is what you have. You can learn more about the various forms of Metaxa by visiting their website.
