In this case, phenylketonuria is the first condition I ever heard of where it could affect your taste buds. I ran into this in high school, when my best friend could taste the slightest amounts of phenylalanine, but no one else in the school could. Our science teacher was very pleased to have him in the class, because he could now dive deeper on genetic conditions, with a real world example right there in the room.

And, as it just so happens, cilantro does taste like soap to me, and I have been a subscriber to nocilantro.com for many years.

And so now, I've been wondering if there's a similar problem with Stevia, where I am again affected negatively. And so I mentioned phenylketonuria as the poster child for that pattern.

Maybe I need to see if there is a nostevia.com domain that I can subscribe to, or create one if not?

Stevia is just fine for me kind of sweet if you don't over do it, but I have known others with the same reaction as yours. I also like licorice, but cilantro barely tastes like anything to me a garnish with nothing to distinguish it from random yard clippings.

I’ve never noticed an aftertaste.

Anything with aspartame in it seems to make me immediately feel nauseous. Not sure if I’m an outlier here.

When Coca Cola released their Stevia sweetened "Coca Cola Life", I thought this was a great compromise between taste and calories. I drank quite a lot of that stuff, and suddenly, from one day to the other, the taste absolutely disgusted me. It just felt horribly artifical, and until today it sends a shiver down my spline just seeing those bottles in the supermarket. No idea what made my brain switch.

Definitely not the only one. Stevia instantly and completely ruins the taste of anything it's in for me, so when I'm looking at energy or hydration drinks I always have to check the labels carefully. Gives me a bit more empathy for people with more serious allergies and sensitivities, I guess.

A percentage of people get a bitter taste from stevia. It depends on the person. I think that’s a big reason why it hasn’t replaced standards like sucralose.

No it takes awful to me as well.

I hate it, it has a terrible aftertaste for me.

It seems to work a lot better when a big company's flavor chemists handle it with other flavors, versus when I try to do it at home. Like MyProtein's vanilla/chocolate stevia-flavored soy protein. Beats the pants off of my own attempts with unflavored soy protein.

Wait... Are you using 100% clean stevia? I thought it is sold in a mix with eritrol, where stevia is a small percent of that mix, because it is 400% more sweetness compared to sugar and to prevent bitter
