I really, really like the Summer Plum. This is the first straight fruit flavor I have ever tasted (I've been looking) that doesn't have even the slightest trace of funky, artificial perfume-like taste. It tastes like very ripe, fresh fruit. It seems like there is just a very slight sweetness, and no tartnesss. It's unusual (in a good way) that there is no tartness, since it seems a lot of fruit juices have that added tartness to help cover up the weird perfume flavor. I would definitely order this flavor but I might add extra flavor - that's just me.
