Stevia is not sweet to everyone. To a small portion of the population with a genetic quirk, it tastes bitter. I am one of those with the quirk, so nothing with stevia tastes good to me. I have had people try to sneak stevia into my food because tehy are sure that if I just don't know it is there, it will be sweet and I will like it. It usually upsets them quite a lot when I spit whatever it is out and ask why they put stevia into it.
