Hi Teo

I suggest that in future you refer to a dictionary instead of asking why.

A bitter taste is not sweet, while something that is sweet contains a lot of sugar. Black coffee is bitter. To make it sweet, you must add sugar to it.

Something hot has a high temperature, while something cold has a low temperature.
Cold Cool Moderate Warm Hot

Hot and Cold tend to be paired as opposites.

Warm and Cool can be paired as opposites.

I honestly don't think you can differentiate between bitter and sour as a "better" opposite for sweet.

Some children seem to love these sour candies that are so popular now, while others prefer sweet. Some people prefer bitter chocolate, some prefer the sweet taste of milk chocolate.

Not every adjective has a pure opposite.

I had the same doubts as GG on this one.

I agree that the opposite of 'sweet' can be either 'sour' or 'bitter' although The New Oxford Dictionary of English defines 'bitter' as 'having a sharp, pungent taste or smell; not sweet'.
The five taste sensations are sweet, sour, salty, bitter, and umami (savory).

The set of tastes is like the set of colors (red, blue, yellow, green, etc.) in that there are no true opposites, rather like the list of the planets (Mercury, Jupiter, ...) or the list of days (Monday, Tuesday, ...) contains no pairs that are opposites.

I would say that warm and cool are opposites, and so are hot and cold.
