I think most Tropicana in the US is from concentrate. "Pure Premium" is their sub-brand for NFC (not-from-concentrate) at the moment; they've previously called it "Tropicana Natural" but were sued since even NFC orange juice requires significant processing to make it last more than a few days.
(Which goes to the other point: most store brand orange juice comes from your local Dole, Minute Maid, or Tropicana distribution center, which is bottling/filling the cartons from concentrate. It's all the same supply chain, the only thing that's different is the brand tax.)
Edit: Weakened the claim about how much is from concentrate, because I'm having trouble finding a statistic.
Second edit: I'm wrong, the majority of orange juice sold in the US is NFC. So this is a market distinction I wasn't aware of.
