I like grape juice particularly Concorde grape juice. It seems to me to be slightly more digestible than standard white grape juice.
I also like pomegranate juice but it is awful expensive compared to grape juice.
pomegranate juice is suppose to be very good for you, but it is spendy.
Grape juice is also suppose to be very good for you (anitoxidents) and much more affordable.
There is nothing as great tasting as white grape juice tho, and mixed with a bit of 7-up is quite yummy as well for a treat.
