Coffee espresso beans have two most important types-Arabica and Robusta that affect the flavor of the coffee significantly.

Coffee espresso beans play the most important and significant role in the coffee making process. The term is misleading, as these are not actually beans but the seeds of the fruit of coffee plant and can be extracted by either wet or dry methods. If measured money wise, coffee has become the second most commonly traded produce and a widely popular drink.

There are two kinds of coffee beans, which are used for commercial purpose. One is ‘Arabica’ and the other is ‘Robusta’. In order to prepare good coffee, Robusta is considered as a bad choice as the caffeine content in it is twice the more than that of ‘Arabica’. On the other hand Arabica is known to have a good flavor and aroma, though its susceptibility to diseases is greater. You just need to choose the best Arabica bean to get a tasteful, fresh and magnificent coffee.

Arabica beans are considered to have the best flavor in the coffee world. These beans are produced in many countries, especially in those where weather, soil and climatic conditions are favorable for these coffee beans. The fact that Robusta can be cultivated in certain environments where Arabica cannot, makes it a cheap replacement for Arabica.

Robusta coffee beans are bitter than Arabica beans and has undesirable flavor. But even Robusta is used in some of the espresso blends to get good froth, if they are of good quality. It also reduces the cost. This is the reason that Robusta has been considered responsible for the pricing crisis during the initial years of 21st century. Robusta coffee is mainly supplied in those countries, where people like to drink dark-roasted and strong coffee. There are certain companies, which are involved in eliminating unwanted flavors from Robusta beans on mass level for marketing purpose.

Nowadays, it is found that green coffee market is full of Robusta beans. Actually, these Robusta coffee beans are being accepted by people and chosen by big industries because of its comparatively low cost. Coffee beans collected from different places have different flavor, caffeine content, body and acidity. All these factors depend on the harvesting conditions, processing and the genetic quality of the coffee beans.

Another coffee bean is called, Caracoli that produces coffee cherry. Generally, Caracoli coffee is produced in all parts of the world but these beans are the most expensive ones.
