Of all the coffee varieties in the world, there are three distinct types that have earned a reputation as being the best types of coffee. The beans are differentiated from the flavour and aroma they take on when roasted. Plus, these varieties are known to produce sub-varieties of coffee. The 3 main types of coffee beans are Robusta, Liberica, and Arabica. Robusta has a higher percentage of caffeine than other varieties and a strong flavour. Liberica is the second variety of coffee but offers the lowest yield in comparison to the other two. Arabica is the most popular and superior variety of coffee distinguished for its aroma and flavour. Arabica and Robusta are used to produce 80% of the world's coffee supply. In fact, some of the best brands of coffee capsules Sri Lanka has to offer are made from the Arabica bean and are the perfect match to Nespresso Capsules. Sri Lanka too, a nation of tea drinkers, is seeing an increase in coffee drinkers.
