Whisk together the wine, lemon juice, olive oil and rosemary in a small shallow baking dish. Add the halibut and turn to coat. Marinate in the refrigerator for 1 hour, turning once. Preheat grill. Remove fish from marinade and season with salt and pepper to taste. Grill the steaks for 3 to 4 minutes on each side or to desired doneness.
