It was a sparkling lemonade/soda with zero sugar or calories, but still tasted sweet enough and highly refreshing when cold. Would also accept a replacement for the non-diet version, which in my region of the US was unavailable even before they got rid of the diet version.
They are still a little sweet, and a liquid will go a long way to make them more in line with what you might want.
Anyways have a nice day!
