I know I am a supertaster or maybe a super-supertaster, although the latter classification was not used in the late '80s when I was part of a study at UCLA.
I can taste the difference between filtered tap water and bottled waters in a blind tasting. The bottled waters ALL have a faint taste that to me is like silicone smells, or hot plastic.
I have had people try to fool me and I can catch it every time.
I don't drink alcohol because I have a severe allergy to it but I do cook with it. I make a meat pie made with Guinness which had, when cooked long enough and with the right ingredients, a hint of bitterness that is good. Raw or not cooked enough, it is like touching my tongue to the base metal on a spoon where the silver plating has worn off. It makes me shudder.
