Different Kind of Coffee Beans

Arabica (As a rule of thumb) is the most popular coffee bean.  It is also the most commercially used. 80% of all the global coffee harvest is Arabica. It is due to mainly two reasons. First, Arabica has the highest yield, which makes it a lucrative harvest for farmers. On the other hand, the end consumers, knowingly, or unknowingly, prefer Arabica coffee beans as it has a sweet and mild flavor.

As far as Robusta is concerned, hardcore coffee lovers prefer this bean, as it has 2.5% more caffeine than any other bean. It tastes earthy, nutty, and buttery.

When the Arabica beans are ripe, the fruit smells like blueberries. 

What are Robusta Coffee Beans?

Robusta Coffee might often be called Vietnamese coffee.

It is because Vietnam is the largest exporter of them. The Natives there prefer Robusta coffee, which explains why they mainly grow this variant of coffee.

Other nations that produce Robusta coffee beans include Indonesia, India, and Uganda.

Robusta coffee plants do not require the extensive care and nurturing that other coffee types need. 

They can grow on sloped land with low soil quality. Most lands that grow Robusta aren’t high enough; thus, rainwater gets trapped on top of them, which ultimately affects the Robusta beans’ taste.

There are two more reasons why Robusta tastes bitter.

First, these plants do not have many nutrients. They grow on impoverished soil, and farmers voluntarily let them grow naturally, without pruning or taking proper care of them. 

Second is, their beans contain higher caffeine as a defense mechanism.

Robusta plants are a wild variant. Over the centuries, they have evolved to produce bitter cherries. This bitterness deters herbivorous animals from devouring all the cherries when they ripen.
