Rinse turkey and pat dry with paper towels. Sprinkle all over with salt, working some under the skin on breast and thighs. Put in a roasting pan, cover with foil or plastic wrap, and chill for at least 24 hours and up to 3 days.
Preheat oven to 400°. Unwrap turkey, discard any juices that have collected in pan, and pat turkey dry. Set aside. In a spice mill or clean coffee grinder, finely grind juniper berries, mustard seeds, and peppercorns. Rub spices all over turkey and set aside. In a small bowl, mix butter, thyme, sage, and rosemary until well combined. Massage mixture all over turkey and place bird in a large stovetop-safe roasting pan. Lay bacon slices over breast and drumsticks. Pour wine and 1/2 cup water into bottom of pan.
Roast turkey 1 hour, turning pan 180° halfway through. Reduce heat to 350° and roast, turning pan every 30 minutes, until a thermometer inserted straight down through the thickest part of breast to bone registers 155°, 1 to 1 1/2 hours.
Transfer turkey to a carving board, loosely cover with foil, and let rest 30 minutes to 1 hour. Pour pan drippings into a glass measuring cup for Pine Nut Gravy, reserving pan to make gravy. Carve turkey and serve with gravy.
