The process to make never concentrated orange juice logistically viable involves removing all the oxygen from the juice so it stores well. Now you can take a seasonal product like oranges and sell the juice the entire year around. Unfortunately removing the oxygen also removes most of the flavor. so what the bottlers do is add an engineered "flavor package" when they bottle the juice to add the flavor back.

I am halfway convinced that flavor wise frozen concentrated orange juice is "closer to the tree" than the "never concentrated" stuff. Nothing on fresh squeezed. But that is the price we pay to have a non-seasonal product.
