Reduce the heat to 350 and cook another couple of hours. The USDA has an informative page
on how to thaw and cook turkeys or check the cooking directions on your turkey. It all varies depending on how large a turkey you have and what temperature you decide to use. Use a meat thermometer at the end to verify. Baste the turkey every 30 minutes, squirting the butter and wine onto the cheesecloth until it's gone. Once it's gone, use the pan juices. If there are none, pour water in the pan and then use that.
