What are the 4 types of coffee beans?
There are four different types of coffee beans, those being Robusta, Arabica, Liberica, and Excelsa. However, the Arabica coffee bean is the most common, making up about 60% – 70% of the coffee that is produced globally. Robusta is also a more common coffee bean used in coffee. Coffee Type — Robusta coffee contains around twice the amount of caffeine as arabica beans. Caffeine helps promote bowel movements so opting for a 100% robusta coffee or a blend may be better for constipation than 100% arabica. Brewing Method — If you want to use coffee to promote bowel movements, brew a strong coffee.
