Why is clean water tasteless?


What is unique about water alone that has a flavour that registers in our head as tasteless?

In: Biology

Most of our taste comes from smell. Water simply doesn’t produce an aroma, so the taste is pretty much “nothing”.

Water is the default solvent for terrestrial life. You have in all the time on your mouth and on the taste receptor cells. So that is the default state and you filter it out as no taste.

Even your own saliva when it is in your own mouth do not taste anything even if it contains other stuff then water for the same reason.
