For me Stevia leaves a mildly bitter aftertaste. I’ve lately been experimenting using a Monk Fruit sweetener mix (available in a mix with erythritol, the main ingredient in Swerve). It’s extremely sweet with no bitter aftertaste I can notice. But drinking unsweetened coffee, tea, and water only, I use any sweetener rarely, for things like Christmas cookies or Thanksgiving pumpkin pie and whipped cream.
Monk Fruit is good, but use it sparingly. It has unpleasant side effects. You probably know what they are.
I drink my coffee dark roast black no sugar. You get used to it.
Stevia leaves a strong black licorice aftertaste for me.
While I rarely enjoy a small amount of black licorice I never want that flavor in anything I am sweetening.
Can’t use it for anything.
