Gather all the ingredients and equipment needed for the slush.

In your blender, combine the wine and frozen fruit. Blend until smooth.

Pour in the fruit juice and simple syrup. Blend again until everything is thoroughly mixed.

Adjust the consistency by adding ice if the mixture is too thick or more frozen fruit if it's too thin.

Taste the slush and add more simple syrup if needed, then blend again.

For best texture, chill in the freezer for about 30 minutes.

Scoop the slush into glasses and garnish with fresh fruit or mint.
