Do you have a source for that? Not that I don't believe you; it's just surprising. My understanding was that orange juice ships poorly, even among fruit juices, which is why the concentrate market was still large.
Edit: I found a survey from 2009[1] where non-reconstituted orange juice was over 50% of the market. So I'm completely wrong about this!
"Not from concentrate" juice is still pasteurised and stored in tanks for months or years before being packaged into the final supermarket packaging, with vitamins, minerals and flavourings added to revive it. It's not any healthier than concentrate, but it is more expensive to store and transport as the water isn't removed.
