For a kid-friendly version, substitute 3 cups chilled club soda for the wine. When adding the wine or soda, pour slowly down the edge of the glass to tame the foam.
Place first 5 ingredients in a blender; process until smooth (about 1 minute). Pour about 1/2 cup strawberry mixture into each of 6 glasses. Slowly pour about 1/2 cup wine into each glass; gently stir to combine. Garnish with whole berries, if desired.
