I made plum wine last year and didn't use enough fruit per gallon (about 20lbs for 6 gal). It is still in the carboy so I am now going to experiment. I just bought some pure prune juice and am going to try and reduce to make a stronger f-pack. Hopefully it will give more of that plummy taste. If not, I have some very sweet blueberry that I might try doing some trial blends and see if that gives it some more body
