In short - blech.
The taste was overly citrusy and had the annoying ability to stick to the tongue so even when you were done with it, the taste was stuck to your palate. It took a lot of water to wash this down. The concentrated flavor might be due to how dense it is (not squishy like a Clif Blocs) but who knows. I have the other two flavors to try out (Fruit Slpash and Berry Blast) and since I tend to like those types of flavors more than citrus, who knows.
