What is a coffee bean?

A coffee bean is the seed found inside the fruit of the coffee plant, known as a coffee cherry. After the outer skin and pulp of the cherry are removed, the seed is dried, processed, and later roasted to develop the flavors and aromas we associate with coffee. Although called a “bean,” it is not a true bean but a seed that contains the natural compounds responsible for coffee’s taste, caffeine, and aroma. Once roasted and ground, coffee beans are brewed with water to create the beverage enjoyed around the world.

There are several species of coffee beans, each offering distinct characteristics in flavor, aroma, and growing conditions. Arabica is the most widely consumed species, known for its smooth taste, pleasant acidity, and complex aromas. Robusta has a stronger, more bitter profile with higher caffeine content, making it popular for espresso blends and instant coffee. Liberica is rarer and stands out for its bold, smoky, and woody flavors, while Excelsa, a variety of Liberica, adds fruity and tart notes that enhance blends. Together, these species contribute to the wide diversity of coffee experiences enjoyed around the world. Arabica, Robusta, Liberica, Excelsa, Coffea stenophylla, Coffea eugenioides, Coffea racemosa, Coffea charrieriana, Coffea kapakata, Coffea humilis are common.
