It currently is owned by Cadbury-Schweppes, true, but it wasn't always. Many years ago when local franchises were awarded, they went to many different bottlers, some of which were aligned with Coke, some with Pepsi, some with other products. Independant franchises don't change when the parent company changes. And local ownership of those franchises may be sold, and changed, but in many places the origanal alignments are still in place - so it's possible that in one county you'll find that Pepper is bottled by Coke, and the next county over it's by Pepsi, and then across the state it might be a 3rd tier bottler.
