Maple Gravy

Pour drippings from turkey roasting pan into a fat separator, and set aside. Place pan on 2 burners over medium-high heat. Add wine and 1 cup stock to pan, then bring to a boil, scraping up browned bits with a wooden spoon. Boil 2 minutes, then add 1 1/2 cups stock and defatted drippings (you should have about 1 cup); bring to a boil. Reduce heat, and simmer 5 minutes. Whisk flour into remaining cup stock, and add to gravy. Simmer until thickened, about 3 minutes. Pour through a fine sieve into a serving dish or gravy boat. Serve hot.
