And yet the flavors are different. Reconstituted raisin water, which I've used in baking, tastes quite different from grape juice. Prune juice doesn't taste like plums either. I'd guess oxidation and perhaps other processes are altering the flavors. I haven't had it in a while, but I think I used to get more of a fresh plum flavor in Serbian plum brandy. Don't know how it's made.
