Common sense of Coffee Why doesn't coffee smell good?

For a long time, many friends have the same question: why does coffee smell good, but it doesn't seem to taste so good?

This is usually the answer to them:

This answer is summarized from a research report by Barry Smith, a professor at the University of London in the UK.

① because we have two odors when we drink coffee, "one is when we inhale from the external environment, and the other is when the smell is exhaled through the nasal cavity."

② the aroma we feel when we drink coffee is that the aroma of coffee is transmitted from the mouth to the nasal cavity after we swallow the coffee, which stimulates the brain to produce a secondary sense of the smell of coffee, but the feeling is not as strong as the smell of coffee when inhaled from the nasal cavity. Although we have taste buds on our tongues, 80% of our tastes are sensed through the olfactory receptors in the nasal cavity.

Another reason for the change in taste may be that 300 of the 631 chemicals that make up the taste of coffee are killed by saliva, which can also lead to a change in the taste of coffee before we swallow.

These are the two reasons why coffee smells good, but it doesn't smell so good when you drink it.
