In a blender, add the frozen strawberries, blackberries and blueberries.
Top with wine, brandy, orange juice and ice.
Blend until combined and the mixture reaches a slushy consistency. If you prefer a thicker consistency for frozen drinks, add more ice and blend again.
Serve in wine glasses or rocks glasses with straws. Garnish it with fresh mint, an orange slice or flash-frozen berries.
Notes
You can use any dry red wine you enjoy. However, the most flavorful ones for any red wine sangria recipe are fruity, dry, full-bodied Spanish wines like Rioja, Tempranillo and Garnacha. You can also use a Cabernet Sauvignon or Merlot.
You can use frozen fruit or fresh fruit in this recipe, but if you use fresh, you may need to add more ice.
Enjoy it right away, as the ingredients will settle. However, if you do have leftover, you can blend it up with a little more ice.
