Remove the turkey from the brine and dry well with paper towels, both inside and out. Repeat this several times, to get as much of the moisture removed. This will help the browning of the skin, as moisture will steam the skin instead of roast it. Place the turkey, back side down, in a roasting pan fitted with a rack. Place the bunch of sage inside the cavity, as the herbs will release their aroma into the meat as it roasts. Let the turkey sit at room temperature for 2 hours prior to being cooked. This will let the turkey warm up, allowing it to cook more evenly. Discard the brine, as it has done its purpose and not safe to re-use.
