Is it okay to brew coffee for too long?

　　cook coffee Is it too long?

　　Coffee should not be boiled for a long time. Because the steam generated when brewing coffee will take away some of the aromatic substances in the coffee and gather it on the surface of the coffee to form foam. The denser the foam, the stronger the aroma of the coffee. If you continue to boil the coffee after it has been boiled, the foam will burst, the aromatic substances in the coffee will evaporate with the steam, and the bitter taste of the coffee will increase.

　　Similarly, it is best to drink coffee immediately after it is brewed. If you wait until it cools down before drinking it, the foam will be destroyed and the aroma will be lost.
