In a large zip bag, combine the wine, garlic, and 1 teaspoon rosemary. Sprinkle the fish with salt and pepper; place fish in the zip bag with the marinade. Zip and chill in the refrigerator at least 1 hour. Remove the fish from the marinade; discard the marinade.
Coat grill with grill spray or rub with oil. Grill fish, covered with grill lid, over high heat 4 to 5 minutes on each side.
Combine the remaining 1 teaspoon rosemary, lemon juice, and olive oil. Spoon over individual servings of fish, and serve immediately with lemon wedges, if desired. Garnish with rosemary sprigs.
