I wished the stuff wasn’t so overwhelmingly bitter to me no matter what I have tried to use for a sweetener.
The bitterness is called “sweetness” to Coffee people. I drink dark roast because less acid and caffeine.
Put a vrty small pinch of kosher salt in your coffee. This cuts bitterness.
Sweetener covers the bitterness, but actually increases bitterness it overlays.
Note I said kosher salt. Iodized salt has a flavor you can taste.
