I had black currant juice when I was in Poland in April. It's much healthier for you than artificial grape in a plastic tube, and you get the black currant syrup in a bottle here. So I found some at my local deli and I've been drinking it for almost 2 months without making a dent in the bottle. I think of it as adult kool-aid, good to drink, good as mix, good on ice cream, healthy. Clearly, this is what you seek.
