A bit like pressurized, carbonated prune juice.

That's prune?

(well, in French 'prune' means 'plum', but I checked out, and apparently in English 'prune' is what we call 'pruneau', dried plums)

Wow, I would have never guessed that the only time I tasted.

Correct. However, because prunes have a bit of a bad reputation in the US, they are sometimes marketed as dried plums as well. Here, they are associated with old people trying to keep their digestion regular.
