The Stevia extract I have tasted (Whole Foods) has - to me - an intolerable nasty bitter after-taste (that is not JUST bitter but a very unpleasant bitterness).
I did taste a Stevia fresh leaf (part of one :-) ) and did NOT notice this bitterness.
So I am wondering - is Stevia intrinsically bitter - or what? Any experience/comments?
(Could the extraction process be causing this bitterness?)
