The Different Types of Coffee Beans There are four primary types of coffee beans grown worldwide with Arabica and Robusta being the most popular. Arabica beans are known for their smooth mild flavor and aromatic complexity while Robusta beans have a stronger more bitter taste with higher caffeine content. Lesser known varieties like Liberica and Excelsa offer unique flavor profiles and are prized in specific regions. The type of bean plays a crucial role in the final taste of the brew influencing its aroma body and acidity.
The Process from Bean to Brew Coffee beans begin as seeds inside the cherries of the coffee plant. Once harvested the cherries undergo processing methods such as the washed or natural process to extract the beans. These are then dried milled and roasted to perfection. Roasting is a critical step as it determines the flavor depth and aroma of the coffee. From light roasts highlighting floral and fruity notes to dark roasts offering bold smoky flavors the process shapes the coffee experience before it reaches the cup.
