Sour Apple flavor is pretty accurate. I don't like sour flavors, so I mix mine with the Vital Reds which makes it taste better to me. I like sugary sweet things and mixing these two together makes the taste fruity, so I have no idea that there is anything plant related inside the drink. I tried the drink mix with just water when I first received it, and the flavor was too healthy tasting to me. I could tell it was a veggie drink.
Bottom Line: Yes, I would recommend this to a friend
