Why do people eat coffee beans? Is eating coffee beans beneficial or detrimental to the body in any way? Does it contain caffeine? These are the answers this article shall be providing.


Coffee Beans

A part of a coffee tree consists of the plant and the seed. The plant can be categorised as a tree since it can grow to about 9 meters long. But farmers cut it short on the farm so it can be easy to harvest. So, when you enter a coffee farm, you will think the coffee plant is just a bush.

The coffee plant consists of Branches, Leaves, flowers, cherries and seeds.

After about three to four years of having primary, secondary, and tertiary horizontal branches, small, delicate white flowers grow at the leaves and branches meeting point. Green cherry-like fruits appear on the flower areas after about six to eight weeks. The cherries change colours and taste from sour to sweet as they grow older.

Each cherry has two tiny peanut-like seeds unless there’s a case of Peaberry. These seeds are the coffee beans that go through a lot of processes for you to get that delicious daily dosage of caffeine.


Types of Coffee Beans

Coffee plants have over a hundred species with different growing methods, caffeine levels and tastes. The most common types of coffee beans include;

  • Arabica
  • Robusta
  • Liberica

Arabica Coffee Beans

Arabica beans are the most popular of all coffee beans and are considered to be of the best quality. These beans take over 60% of coffee beans produced in the world.

Arabica beans are known to have special needs such as a high-altitude environment to grow, plenty of shade and steady rainfall. However, they are delicate to deal with and can be affected by environmental inconvenience.

The beans are well known for their distinct flavour and aroma, among other coffee beans.

Robusta Coffee Beans

Robusta coffee beans have a smooth texture and a slightly chocolatey taste, making them go well with sugar and milk.

These beans have twice the amount of caffeine in Arabica and give a more robust flavour.

Liberica Coffee Beans

Liberica beans are scarce to come by. They are highly smoky, floral and fruity with a unique aroma.

Liberian beans have an irregular shape compared to other coffee beans. They are also more significant than the rest.

Excelsa Coffee Beans

Excelsa coffee beans are productive and resilient beans that require extensive care to get the best of them. The leaves and flowers are often leathery and large.

These beans grow best in vertical space and altitudes between 1000 and 1,300 m.a.s.l.
