My first Surinam Cherry - can't wait for it to ripen

Here's my little 2 year old, 2 foot tall Surinam Cherry (Eugenia Uniflora) grown from seed.

I can't wait for it to ripen. See, I bought red and black seeds. After tasting some red ones (grown as a hedge) on my morning walk, I'm hoping its the black one, apparently they taste much better. The red one I tasted, tasted like a mixture of sugar, tomato, turpentine and resin. Unfortunately, only one of the black seeds germinated, but all three red seeds germinated. I have planted all four plants and don't know which one is the black one anymore - moral of the story, label your plants and pots well. Fortunately its a beautiful little shrub (or tree if left to grow), so I intend on keeping the red ones even if they taste horrible. (I might remove them later when some of my other seedlings are large enough to plant, i.e. feijoa's).
