The three main beans
Known as one of the most popular and well known types of coffee bean, Arabica beans are the most commonly produced variety and are considered higher quality beans. In fact, over 60% of the coffee beans in the world that are produced are Arabica variety.
As the name hints, the Robusta bean is both hardy and is also immune to a variety of diseases too. Compared to Arabica beans, those that grow on the Robusta plant have double the amount of caffeine in them, meaning that they are an excellent choice for a real boost and offer a more harsh flavor.
One of the hardest types of coffee bean to come by is the Liberica bean. They are larger than the other beans and is the only one in the world that is known to have an irregular shape. Liberica beans are also unique in their aroma and some say that they are not only smoky, but they are fruity and floral too.
