Coffee bean is a seed from a coffee plant. The fruits of the coffee plant have two stones with flat sides together. Coffee beans have endosperm which contains from 0.8 to 2.5% caffeine. This caffeine cultivates coffee plants.

Coffee beans are the number one export products for almost all countries all over the world. Coffee plants come from five species: coffea Arabica, coffea benghalensis, coffea canephora, coffea liberica and coffea stenophylla.

Each species produces slightly different characteristics. Coffea Arabica comprises 70% of world's coffee trade. Coffea canephora (synonym of Coffea robusta) cultivates in places where coffea arabica is not thriving. Coffea liberica and coffea excelsa grows in very limited lands.

There are already many varieties of coffee beans anywhere in this world. More and more coffee companies develop newer flavors of coffee beans. There are herbal coffee beans developed also.

Arabica and robusta beans are the two most popular coffee beans. As earlier stated, Arabica comprises 70% of coffee all over the world. This is the highest quality of coffee, and consequently also the most expensive.

There are already different varieties of Arabica that produce a very wide range of taste. Sweet to tangy and soft to sharp, these varieties have already been produced. Even their unroasted smell is like sweet blueberries. While they are roasted, the smell is so sweet and fruity.

These kinds of coffee are delicate ones. They need higher elevation of land about 600 to 2000 meters to grow. It needs cool and subtropical climates. It needs more rain and humidity. It also needs good kind of soil and away from too much heat. It needs a good mix of sun and shade. They are very vulnerable to any kind of pest.

On the other hand, Robusta beans taste from neutral to harsh. They are the grainy type of coffee. It has the type with oatmeal flavor that people love. Its unroasted smell is like raw peanuts.

It is rare to find high quality robusta beans. They are mostly reserved for espressos. Most Italian coffee brands use Robusta.

Robusta is a hard and tough kind of plant. These can be grown in the altitude of 200 to 800 meters. They continue to flourish in this kind of elevation. They can stand rougher handling and are more resistant to pests. Because of these reasons, they yield more finished products at lower production costs. They also contain twice the caffeine Arabica beans have.

The processing of coffee starts with the conversion of raw material to commodity green coffee. It is only the coffee fruit or bean itself that is used in the plant. The seed is separated then dried.

Adding flavor to the coffee bean is varied. There is a wet, dry and semi-dry process.
