What do coffee beans look like?

Coffee beans are seeds from the coffee tree that are commonly used to make coffee beverages. They have a unique appearance and morphology, characteristics that are important in determining their quality and taste.

First of all, the appearance of coffee beans is usually oval or flat. This depends on the different varieties of coffee trees and the growing environment. In most cases, oval beans are considered high-quality beans and are more popular in the market.

Secondly, in terms of color, mature coffee beans appear dark brown or black. This is due to the rich soluble substances and oils inside, which produce aroma and flavor after the roasting process. However, in some special cases, such as after brandy or red wine processing, other color changes can also be seen.

In addition, a fine and evenly distributed wrinkled texture can be seen on the surface. This texture is called "lace" and is an important indicator of the freshness of the beans and whether the storage conditions are good. Fresh coffee beans usually have clear lace, while aged or damp beans will lose this feature.

Finally, coffee beans also have certain size and shape differences. Generally speaking, large beans are considered a symbol of high quality and are preferred when making full-bodied coffee. However, in some cases, small or irregularly shaped beans can also produce special flavors and tastes.

In short, coffee beans attract people's curiosity about quality and taste with their unique appearance. Whether it is oval, dark brown, with lacy texture or different sizes, these appearance characteristics are closely related to the experience of drinking coffee in the cup.
