Step 1

Add wine, lemonade concentrate, powdered sugar and 4 cups of ice cubes in a blender. Blend until slushie consistency is reached. Add up to 2 more cups of ice if needed (I used all 6 cups).

Step 2

Pour into 4 wine glasses and add a lemon slice to the rim. Serve with straws for sipping. Pour any leftovers into a freezer bag and freeze. When ready to drink again, dump into blender and blend, adding a little water if needed.
