Ah I see. It depends on where/which country you are I guess. As a couple examples, if you're somewhere with a Target, Simply Orange [1] claims to be pasteurized, whereas Tropicana does not [2], and neither is from concentrate. Although it's possible they both are pasteurized and the labeling isn't required... I don't know if it is.

However, if your next-best option is pasteurized juice, that sounds... just fine, if not even better? I mean I hope you're not finding pasteurization a horrifying Big Ag conspiracy of some sort. And pasteurization seems like a pretty plausible explanation of the difference you see compared to what you squeeze yourself... so then what's the huge worry?
