Dip peaches, 1 at a time, into boiling water to cover 1 minute. Plunge peaches immediately into ice water to stop the cooking process; drain and slip skins off. Cut peaches into quarters.
Bring sugar and 1 cup water to a boil in a large saucepan over medium heat. Reduce heat, and add peach quarters; cover and simmer 5 minutes. Cool.
Process peach mixture in batches in a blender until smooth, stopping to scrape down sides.
Stir together peach mixture, whipping cream, wine, and lemon rind; chill. Garnish, if desired. Chill 2 hours.
Prep: 15 min., Cook: 5 min.
