What Is Arabica Coffee? The World’s Most Popular Coffee Bean

If you’ve ever wondered why some coffees taste bright and complex while others taste harsh or bland, the answer often starts with the coffee plant itself. Not all coffee is created equal—and much of what makes the best-tasting cups possible comes down to the species of coffee tree it comes from.

The vast majority—about 70%—of the world’s high-quality coffee beans come from just one species: Coffea arabica, or Arabica. That includes famous coffees like Jamaican Blue Mountain and Yemeni Mocha. But what makes Arabica so widely loved, and how does it differ from the other main coffee species?

What Is the Arabica Coffee Tree?

Arabica coffee originates from Ethiopia, the birthplace of coffee cultivation. It is the dominant coffee species worldwide, responsible for roughly 70% of global production. Iconic coffees such as Blue Mountain and Mocha are almost exclusively Arabica. These trees thrive at higher altitudes—ideally between 500 and 2,000 meters above sea level—and produce better quality beans the higher they grow. They prefer cooler temperatures, well-drained soil, and partial shade, but are more delicate than other species.

How Arabica Compares to Other Coffee Species

While Arabica dominates the specialty market, it isn’t the only coffee species grown. Two other major species are Robusta and Liberica, each with distinct characteristics.

Robusta Coffee Trees

Originating in the Congo region of Africa, Robusta makes up about 20–30% of the world’s coffee production. These trees are far hardier than Arabica and can grow at low elevations—below 500 meters. They tolerate poor soils, resist pests and diseases, and require minimal care. However, Robusta beans produce a harsher, more bitter cup with less nuanced flavor. Because of their resilience, Robusta plants are often used for instant coffee and are common in commercial blends found in many diners and fast-food chains. They yield more coffee per plant and are cheaper to produce overall.

Liberica Coffee Trees

Liberica comes from Liberia in West Africa and has a much shorter cultivation history. It accounts for less than 5% of global production. This species is grown in only a few places, including Liberia, Suriname, and Guyana. Liberica trees do well at low altitudes and produce beans with an intense, strong aroma and a distinctly bitter taste. Though rare, Liberica offers a uniquely bold profile compared to the more common Arabica and Robusta.

Why Altitude Matters for Arabica Flavor

One of the biggest factors influencing the taste of Arabica coffee is altitude. The ideal growing range is 500–2,000 meters, and within that range, the higher the elevation, the better the potential cup quality. At higher altitudes, the temperature is cooler and the growth cycle slows, allowing more complex sugars and acids to develop in the coffee cherry. This results in a more vibrant, aromatic, and nuanced cup. That’s why high-altitude regions like Ethiopia’s Yirgacheffe or Jamaica’s Blue Mountains are famed for producing some of the world’s most distinctive Arabica coffees.

Frequently Asked Questions

What is the most popular type of coffee bean in the world?

The most popular and widely produced high-quality coffee bean is Arabica, accounting for approximately 70% of global coffee production. It is favored for its smoother, more complex flavors compared to other species.

What are the main coffee species?

The three main coffee species are Arabica, Robusta, and Liberica. Arabica makes up around 70% of global production, Robusta about 20–30%, and Liberica less than 5%.

Where does Arabica coffee grow best?

Arabica coffee grows best at higher altitudes between 500 and 2,000 meters, in regions with cool temperatures, well-drained soil, and moderate sunlight with some shade. Higher elevations generally produce better flavor profiles.

Why is Robusta coffee cheaper than Arabica?

Robusta coffee is cheaper because it is easier and cheaper to grow. The plants are hardy, resistant to pests and disease, grow at lower altitudes, and produce higher yields per plant. They also require less manual care and can be harvested by machine.

What does Liberica coffee taste like?

Liberica coffee has a very strong, bold aroma and a distinctive bitter flavor. It is much less common than Arabica or Robusta and is mostly grown in parts of West Africa and South America, including Liberia, Guyana, and Suriname.

Does altitude affect coffee flavor?

Yes, altitude significantly affects coffee flavor. Higher altitudes tend to produce slower fruit maturation, leading to greater sugar development and more complex, nuanced flavors in the coffee beans, especially in Arabica varieties.
