Let’s start with the Wikipedia page on it. Unfortunately, a lot of good info of the different types of supertasters has been edited out. So it seems there is only one type if that was all you had to go on.
The current version has a really weird line: “Subsequently, salt has been replaced with a non-oral auditory standard.” WTF?
I am a double supertaster. In addition to the usual hate for bitter things like broccoli and it’s kin, I am sensitive to alcohol and fats. So for me beer is doubly bad: bitter plus the alcohol. But other supertasters might have less an aversion or none at all to beer.
People have falsely accused me of being a picky eater. I routinely eat many foods that I don’t like much at all. But if something is really awful, forget it. And that “Well, you’ve never had X that was prepared right.” Uh, nope.
It’s like having regular color vision in a world dominated by people with red-green colorblind. If you’re sight/taste/hearing isn’t as good as someone else’s, that doesn’t mean there is something deficient with the other person.
OTOH, you have no idea how great chocolate tastes to me. It is amazing. (If the fat content isn’t too high.)
