Explanation:

Taste is a subjective sense because it depends almost completely on the person doing the tasting. Because taste cannot be numerically measured, what each taster perceives in a flavor is what gives tastes its uniqueness and score.

If taste were objective, everyone would detect exactly the same taste in even the most complex of flavors. Thousands of people would be able to try the same soup and they would assign it the exact same taste score. This is not the case since individual taste buds and experience also dictate how something will taste.
