Qianjie-A brief introduction to the types and ingredients of coffee beans

What are the varieties of coffee beans?

Arabica species (Arabica)

The Arabica species, which originated in the Ethiopian plateau, was originally used as medicine and formed the habit of baking in the 13th century, until it was introduced into Europe through Arabia in the 16th century and became a popular drink throughout the continent. It then followed in the footsteps of European colonists and became one of the most popular drinks in the world.

Robusta species (Robusta)

Robusta is a species found in the African Congo. It has a strong resistance to leaf rust, but because of its strong smell, few people drink it directly.

Usually, as long as a cup of coffee is mixed with 34% robusta beans, the whole cup of coffee will taste like robusta coffee.

Laiberian species (Liberica)

Leibiria is mainly produced in West Africa, and it is highly adaptable to the environment, but it is unable to resist leaf rust, and its flavor is not as good as that of Arabica, so it is only traded in West African countries, including Libya and Ivory Coast. it is difficult to find traces of the Laiberian species in the international market. The appearance is spoon-shaped.

Coffee bean composition

Water protein, fat sugar (sucrose), chlorogenic acid, caffeine, amino acids, these are the main factors affecting the coloring, aroma and flavor of coffee beans.

Knowledge expansion: caffeine accounts for 0.9% Mel 1.4% in Arabica: Carneflari usually accounts for 2%, more than 3% in more cases
