Introduction
Coffee is a diverse and complex beverage, with different flavors, aromas, and textures depending on the type of coffee bean used. While there are over 120 species of coffee plants, only a few are cultivated for commercial production. The four main types of coffee beans—Arabica, Robusta, Liberica, and Excelsa—each have unique characteristics that influence the taste and quality of the coffee.
In this article, we will explore the differences between these coffee beans, their flavor profiles, and the best ways to enjoy each one.

Arabica vs. Robusta: Which One Is Better?
The choice between Arabica and Robusta depends on personal preference and how you like your coffee.
