Add water, 2 cups strawberries and sugar to a medium saucepan. Bring to a boil and reduce to a simmer. Simmer 10 minutes and use a potato masher or fork to smash the strawberries. Simmer another 5 minutes. Cool.
Push mixture through a fine sieve, reserve the liquid and toss anything you couldn't get through the sieve.
Add strawberry mixture, wine, vodka and remaining 2 cups of sliced strawberries to a large pitcher. Let sit for one hour.
Just before serving, add sparkling water and raspberries. Serve over ice.
