There are two varieties of coffee: Arabica and Robusta.

At present, the main varieties of coffee grown in the world come from two original varieties: Arabica and Robusta. The planting methods, growth environment and other conditional characteristics of the two are different, and even the caffeine content is quite different.

Arabica

Robusta

Mostly found in tropical Central and South America

Of Madagascar in west-central and eastern Africa and Indonesia in Asia

Planted on an alpine slope at an altitude of 900 mi 2000 meters.

Planted on an alpine slope at an altitude of 200 Mel 600 meters above sea level

Need a high degree of manual intensive care

By contrast, it doesn't take much manpower.

The taste is rich.

The taste is poor and bitter.

Low caffeine content

The caffeine content is about twice that of Arabica.

The price is higher

The price is lower

The shape of the bean is small, the front is long oval, the middle crack is narrow and tortuous, and the arc on the back of the bean is smooth.

The bean shape is larger, the front is gradually round, and the back is round and straight, a bit like barley seed.

Since coffee fruits are not ripe on the same tree at the same time, high-quality coffee must be picked by hand. About 75 per cent of the world's coffee is Arabica, but only 10 per cent is coffee that can be used in high-end coffee shops. If coffee beans produced from one country or region have not been mixed with other coffee beans, we call them single-source coffee beans.

The types of Arabica coffee trees include: Bourbon,Typica,New modern nybrids caturra, Catimor and Variedad Colobiana.

Growing environment: coffee grows in a treeless climate with medium rainfall and plenty of sunshine. The main coffee growing regions in the world are the Americas, Africa, the Arab region and Indonesia. Coffee is grown in about 80 countries in these regions.

Coffee tree fruit will show a bright red after ripening, commonly known as "coffee cherry fruit (Coffee cherry)", after picking the fruit, you can go to the "cherry fruit" coffee beans, usually a fruit covered with two oval raw beans.

The opposite side of two raw beans in the fruit is called flatbean. The fruit of some coffee trees is covered with only one raw bean, which is called single-bract bean or round bean (peabery).

In botany, coffee trees belong to the evergreen trees of the subgenus Rubiaceae, and coffee beans, commonly known as coffee beans, are actually the seeds of the fruit of coffee trees. They are called coffee beans only because they are shaped like beans. Climate is the decisive factor in coffee cultivation. Coffee trees are only suitable for growing in the tropics or subtropics, between latitudes of 25 degrees south and north.
