Could also just say different - children also have an unlimited tolerance for things that are sweet. Some adults I think never get past it much & have what I call super smellers too. But yea it’s like they can also lack the tastebuds that’d help them appreciate bitter things later in life, like most adults do. Could just be natural that our tastebuds from when were kids change or die off sorta, which allows for the fuller palate.

Tbh though I can’t stand bitter & earwax level IPAs. Just gives me headaches.
