Actually supertasters have palettes that are more sensitive than others, but they tend to be picky eaters. I would be surprised to see a supertaster who likes to vape coffee or chocolate flavors and the like where the real life food or drink counter part is bitter.
This +100%
Picky eater here. Maybe that's why I have a hard time with juices. I can tell that they don't capture the exact flavor. Apple is the worse for me. They all taste like imitation. With food, I can almost duplicate a dish because I can pick out the seasonings used. With juice I sometimes get what they are trying for. But god forbid if there is a nasty note to it, I will find it.
Edit to add: some of my favorite juices are those that I don't have a clue what the 'real life' flavor tastes like. So I don't have a base to compare it with.
