The Two Main Coffee Species You Should Know

If you’ve ever wondered why some coffees taste bright and complex while others are harsh and bitter, part of the answer lies in the species of the coffee bean itself. With over 60 known coffee species, most people drink just two—but knowing which ones can transform how you choose, brew, and enjoy coffee.

There are at least 66 identified coffee species, but only two dominate global production: Arabica accounts for roughly 65% of the world’s coffee market, and Robusta makes up about 35%. A third species, Liberica, contributes less than 5% of global output.

What Are the Main Coffee Species?

Coffee drinkers encounter mainly three species: Arabica, Robusta, and Liberica. Arabica is celebrated for its nuanced flavours, higher acidity, and sweeter profile. Robusta, on the other hand, is stronger, more bitter, and contains nearly double the caffeine. Liberica is rare, with a distinctive woody, smoky flavour and an irregular bean shape.

Why Arabica and Robusta Dominate

Arabica dominates around 65% of the specialty and commercial coffee markets due to its preferred flavour profile and suitability for higher altitudes. It is grown in regions like Latin America, East Africa, and parts of Asia. Robusta, accounting for approximately 35%, is valued for its hardiness, disease resistance, and high caffeine content, making it common in espresso blends and instant coffee. With less than 5% of global production, Liberica is grown in niche areas such as Malaysia and the Philippines, but rarely exported on a large scale.

How These Species Influence Your Coffee

The species of coffee bean directly impacts flavour, aroma, body, and caffeine level. Arabica beans typically produce a smoother, more acidic cup with notes of fruit, berries, floral, or chocolate depending on origin and processing. Robusta offers a heavier body, more bitterness, and a pronounced earthy or nutty character, often used to add crema and strength to espresso. Liberica, when available, delivers a unique, smoky taste with a full body, but its irregular cultivation limits its role in the global market.

Frequently Asked Questions

What are the three main coffee species?

The three main coffee species are Arabica, Robusta, and Liberica. Arabica makes up around 65% of global production, Robusta about 35%, and Liberica under 5%. Arabica is known for its nuanced, often sweeter flavour, while Robusta is stronger and more bitter with higher caffeine. Liberica is rare and has a distinctive woody, smoky taste.

Which coffee species is better for espresso?

Robusta is commonly used in espresso blends for its bold flavour, heavy body, and high caffeine content, which contribute to crema. However, many espresso blends include a percentage of Arabica for balance and complexity. Some specialty espressos use 100% Arabica, depending on desired flavour profiles.

Why is Arabica more popular than Robusta?

Arabica is more popular due to its smoother, more complex flavour profile with higher acidity and fruity or floral notes. It is generally considered to produce a more refined cup, especially in specialty coffee. Robusta is stronger and more bitter, often used for its caffeine kick and crema in traditional espresso.

Does Liberica coffee still exist today?

Yes, Liberica coffee still exists but makes up less than 5% of global production. It is grown in limited regions, primarily Malaysia and the Philippines, and is rarely exported. Its unique smoky, woody flavour and irregular bean shape make it a niche offering in the coffee world.

What’s the difference between Arabica and Robusta beans?

Arabica beans are known for their higher acidity, complex flavours (often fruity, floral, or sweet), and lower caffeine content. Robusta beans are more bitter, have a heavier body, higher caffeine (almost double), and are more disease-resistant. Arabica grows at higher altitudes and is more delicate, while Robusta thrives in lower, hotter regions.
