I’ve always wondered. Then, some years back, I assumed that they simply slice open the prunes and boil them in water, thus diluting the inside mushy stuff with water. But then I took a closer look at the label of prune juice and read, I’m not making this up: “NO WATER ADDED”(!).
So how exactly do they make prune juice? Does anyone know?
Plum juice and prune juice don’t taste the same. My WAG is that the drying process changes the sugars in the artists-formerly-known-as-plums. As for the no-water-added thing, I think there is a standard recipe for making prune juice and no water added means “no water above that called for in the recipe.”
Incidentally, I’ve seen prunes labeled as “dried plums” lately. Must be a new government ruling.
I read that it was a ploy to get more people to eat prunes. The prune industry has determined that the word prune carries a negative connotation (i.e., old people eat them). Dried plums have no negative connotation. Sorry, no cite.

Plum juice is available but hard to get - the few times I’ve seen it is usually as some East Asian branded drink, eg Korean.
It’s like cherry juice - that seems to be appearing a bit more now, but generally when I find a carton it come from Hungary or Eastern Europe or somewhere.
Here (as well as fresh apricot) they also drink dried apricot juice, presumably made in a similar way to prune juice. It tastes much as you’d expect, like dried apricots. Pleasant, but without the wonderful tang of fresh apricot juice (maybe that’s from the Vitamin C before it breaks down, or added Vit C for preservative?) This dried apricot juice is a traditional drink at iftar (the breaking of fast at sunset during the month of Ramadan). They also have a tamarind juice, which may be made from dried tamarinds as well.
My guess is that it’s some USDA restriction that the end water weight of the prune juice must be equal to or less than the initial water weight of the prunes.
But there is no specific provision for the words “water added” or “no water added.” If the prune juice contains less that 18.5 percent by weight of water-soluble solids extracted from dried prunes, then it simply ceases to be prune juice. The use of the label declaration “no water added” is somewhat questionable. Almost like they are trying to say they have more prunes in their prune juice than other brands, when actually they all must conform to the regulation.
