Is instant coffee made of real coffee? How do you get coffee beans?

First of all, instant coffee is really made by coffee. But coffee beans are not "beans", but seeds.

Coffee is a kind of fruit, which is often called "coffee cherry" because of its round red appearance. Usually a fruit has two seeds, and a small number of those with only one seed are called Peaberry. After harvesting the fruit, coffee farmers will carry out a series of treatments, and the difference depends on how to remove the pulp from the outer layer of the seed. Different treatments will affect the flavor of coffee. Then it will be dried and baked before a cup of coffee can be made.

At this stage, there is a difference between instant coffee and coffee beans.
