Place the turkey wings, turkey neck (if using), onion, carrot and celery in a roasting pan and add olive oil. Mix together. Add the white wine and enough water to cover bottom of pan. Roast in 425° oven for 1 to 1 1/2 hours or until wings are a deep golden brown. Check occasionally during roasting to be sure the bottom of the pan is covered in liquid so as not to burn. If not, add more water.
