The shape characteristics of coffee beans revealed: from small and round to oval and flat, their secrets are here!

Coffee beans are an indispensable part of our daily life. Whether it is a morning pick-me-up or a companion to afternoon tea, we cannot do without them. However, have you ever wondered why coffee beans come in various shapes? Today we will reveal this question.

1. Small and round

Small, round coffee beans are often called "pearls" or "balls." They appear as a perfect, smooth, uniform sphere. This shape is often seen in Arabica coffee, as the Arabica variety is more focused on taste and aroma.

So why do some coffee beans appear small and round? There are two main reasons. First, they are exposed to good environmental conditions and sufficient sunlight during the growth process, allowing the fruits to grow evenly. Second, these coffee beans are strictly screened during the picking and processing process, and only the most perfect beans can be selected.

2. Oval flat

The opposite of the small and round shape is the oval and flat shape of the coffee beans. This shape is usually called "cake" or "plate". Oval and flat coffee beans are mainly found in the Robusta variety, which focuses more on richness and bitterness.

So why do some coffee beans appear oval and flat in shape? The reasons can also be attributed to two points. First, during the growth process, they were exposed to poor environmental conditions and insufficient sunlight, which prevented the fruit from growing evenly. Second, during the picking and processing process, they were not strictly screened, resulting in some imperfectly shaped beans being retained.

3. Intermediate state

In addition to small and round and oval and flat, there are also some coffee bean shapes in between. These beans are neither completely round nor completely flat, but are oval or oval. This intermediate state of coffee beans is often called "egg-shaped".

So why do some coffee beans take on an intermediate shape? The reason can be attributed to two aspects: environment and selection. During the growth process, these coffee beans are subject to a certain degree of environmental influence, with both good conditions and certain restrictions. During the picking and processing process, they undergo a certain degree of selection, but there is no strict requirement to keep only the most perfect beans.

4. Influencing factors

In addition to the environment and selection, there are other factors that affect the shape of coffee beans. The first is the variety difference. There are obvious shape differences between different varieties. The second is the processing method. Different methods used in the processing process will also lead to different shapes. Finally, the roasting level. Mastering the right temperature and time during the roasting process can also change the appearance of coffee beans.

In summary, the shape characteristics of coffee beans are the result of the interaction of many factors. Whether it is small and round, oval and flat, or in between, each shape has its own unique charm and taste. I hope that through this article, you can have a deeper understanding of the shape of coffee beans.
