black carrot and hibiscus?

Today for lunch I popped out to M&S, which is a supermarket in the UK.

With my combo meal I got an M&S Cola. Right on the front it claims “no artificial colours”. And based on the ingredient list, I’ll go along with agreeing.

However, near the end of the ingredient list is ‘fruit and vegetable concentrate (black carrot and hibiscus)”. I never would have thought of putting either into a Cola, but it doesn’t taste bad. I’ve heard of both being in teas, but never a soda.

Who knew such a variety of sources can be utilized for flavoring?
