For the hard cider brine, in a large brining bag or in a large stock pot, add hard cider, cider, kosher salt, bay leaves, onion, Worcestershire sauce, peppercorns, and parsley. Add the turkey to brine and cover with water. Refrigerate overnight.
Preheat oven to 450°F and align a rack in the lower third of the oven.
Remove the bird from the brine and pat dry with paper towels. Drizzle with EVOO and season with salt and pepper and place into the oven. Check on the turkey after 40 minutes and tent with foil if getting too dark. Roast until the turkey reaches 160˚F, about an hour and a half. Set aside to rest.
