Why do newly bought coffee beans have no aroma?

Coffee is a must-have drink for many people every morning. It not only refreshes the mind, but also has a unique aroma. However, when we buy fresh coffee beans and find that they do not have the expected aroma, we may be confused. So why do newly bought coffee beans have no aroma?

First, we need to understand the changes that coffee beans may undergo during production and transportation. Freshly roasted coffee beans usually have a rich and fragrant aroma. However, during long-term storage or transportation, these aromas may gradually dissipate.

Secondly, the roasting process will also have an impact on the coffee beans. Different degrees and times of roasting will cause the coffee beans to release different types and intensities of aroma. If you buy lightly roasted or darkly roasted coffee beans with a longer time (such as low temperature and slow fire), the aroma may be relatively weak.

In addition, during the cooling and packaging process, coffee beans may also lose some of their aroma. During the cooling process, heat will gradually dissipate, which may cause the loss of aroma. During the packaging process, if no sealing measures are taken or the packaging bag is not tight enough, air and humidity will enter the packaging bag, further affecting the aroma of the coffee beans.

Finally, before using your newly purchased coffee beans, make sure you store them properly. Coffee beans should be stored in a dry, cool, dark, and odor-free environment. If exposed to humidity or high temperatures, coffee beans can easily become damp and deteriorate, and lose their original flavor.

In summary, if you buy fresh coffee beans and find that they do not have the expected aroma, it does not mean that these coffee beans are inferior or problematic. On the contrary, a variety of factors may cause their aroma to be lost or weakened. In order to get a better taste and experience, please make sure to store and use the fresh coffee beans you buy properly.
