Do you wake up in the morning because of the pleasant coffee aroma? Well most of us do!Coffee provides us a “pick me up” we need every morning, but did you know that aroma is not just about the smell? Aroma is responsible for all the coffee attributes other than the mouthfeel and sweet, salt, bitter, and sour taste that is perceived by the tongue. Therefore, aroma might consider as the most important component of specialty coffee.
Roasting triggers the chemical process within the beans causing the development of volatile compounds that contribute to the aroma profile. But not all coffee beans provides a strong scent like the green coffee beans which have a limited aroma that is often described as providing green or musty notes.

2. It can be taste through our mouth by swallowing, and aromatic volatile compounds drift upward into the nasal passage.
