What do coffee bean seeds look like?

Coffee beans are a common raw material for making coffee. They are seeds picked from coffee trees. After being processed and roasted, these seeds become the coffee beans we are familiar with. So, let's take a look at what coffee bean seeds look like.

First of all, the appearance of coffee beans is an oval or egg shape. Usually, they are slightly larger than ordinary peas and have a smooth and shiny surface. This appearance feature makes it easy for people to identify them.

Secondly, in terms of color, unroasted coffee beans appear light green or dark green. However, after being roasted, they turn into varying degrees of brown or dark brown. This color change is caused by the reaction of internal chemicals at high temperatures.

In terms of texture, freshly picked coffee cherries contain two seeds that are connected and tightly bound together (what we call the "pulp"). When processed, the "pulp" is removed and the remaining seeds are washed and fermented. These seeds are then dried to form the coffee beans we are familiar with.

Finally, coffee beans have a thin, hard outer shell called the "pericarp". During processing, the "pericarp" is also removed. This shell is an important layer that protects the coffee bean from the outside environment.

In summary, coffee beans are seeds picked from coffee trees. They are oval or ovoid in shape and have a smooth and shiny surface. They are light green or dark green when unroasted, and become different shades of brown or dark brown after roasting. In addition, they also contain a hard and easy-to-peel shell. The "pulp" is connected and tightly combined with the seeds, which is removed during processing.

By understanding what coffee bean seeds look like and their characteristics, we can better understand the various steps required from the farm to the cup, and appreciate the effort and care behind every cup of fragrant and delicious coffee.
