What do coffee beans look like? Uncover the true face of coffee beans!

Coffee beans are one of the most common foods in our daily life. They are the raw material for making coffee. So, what do coffee beans look like? Next, let's reveal the true face of coffee beans.

First of all, coffee beans are oval or ovoid in appearance. They usually have two smooth and shiny surfaces and a certain degree of curvature. This special shape makes them easier to separate and handle during processing.

Secondly, in terms of color, mature coffee beans usually appear dark brown or dark brown. Different types and varieties of coffee beans may have slight differences, but generally have this color characteristic.

In addition, in terms of texture, the skin of the coffee beans is relatively hard and covered with a layer of fatty oil. When you press it gently with your fingers, you can feel the hard and firm texture.

In addition, there are important changes in the internal structure. Before roasting, the original coffee bean is wrapped in a thin and sticky layer of pectin, which is formed during the ripening process of the coffee bean. After roasting, the pectin will be completely removed, leaving the coffee bean we are familiar with.

Finally, in terms of size, coffee beans come in all sizes. Generally speaking, larger beans tend to be more popular because they are easier to control during processing and roasting. However, not everyone likes large beans, as small beans can also produce a rich and delicious cup of coffee.

To sum up, in the original state, coffee beans are oval or egg-shaped, dark brown or dark brown in color, with a hard skin covered with a layer of fatty oil. After being roasted, the hard texture is retained but the sticky pectin is lost. There are differences in size. These are the rich and aromatic coffee beans that we see in their true original appearance after the secret is revealed.
