The types of coffee or the coffee varieties are the derived subspecies from the coffee plants. They are either selectively bred or naturally selected. Coffee plants can be either cultivated or wild. And only a few wild varieties are considered as commercially important because of presence of characteristic traits such as fruit yielding trait and disease resistance trait.
There are mainly 2 types of coffee beans that are available commercially.
- Coffee Arabica
- Coffee Robusta
Both the beans have different kinds of taste and this taste depends upon how they have been grown and where they have been grown. People can also use a combination of both the beans to produce a unique taste.
