Combine chicken stock, vegetable stock, and with wine in a large pot. Toss in apples, oranges, lemons, pear, garlic, and onion. Tie rosemary, thyme, and sage together with kitchen twine; add to the pot. Stir in 1 cup water, salt, sugar, dried peppers, vegetable flakes, peppercorns, and bay leaves. Bring to a boil; stir to dissolve salt and sugar. Remove brine from heat and let cool to room temperature. Store in the refrigerator. Combine brine with 1 gallon of heavily iced water 1 to 2 days before serving the turkey. Place thawed turkey in an extra-large turkey bag and pour in enough brine to cover completely. Refrigerate. Remove turkey from the brine and rinse inside and out with cold water. Discard brine and start cooking.
