5 Main Types of Coffee Species Explained

Ever wonder why your favorite pour-over tastes floral and bright while instant coffee is harsh and bitter? The answer lies in the species of coffee bean—something most drinkers overlook, but that shapes every aspect of your cup.

There are over 5,000 coffee varieties within 500+ species in the Coffea genus, but for drinking purposes, coffee falls into five main types. Of those, Arabica accounts for more than 70% of global production, while Robusta makes up most of the rest.

What Are the Five Main Coffee Species?

From a drinker’s point of view, coffee species can be grouped into five broad types. Two are familiar: Arabica and Robusta. The others—Liberica, Excelsa, and a small number of wild or less-cultivated species—are far rarer in commercial trade.

Arabica and Robusta dominate the global coffee supply chain, with Arabica leading by a wide margin. Each species has traits that affect how it’s grown, processed, roasted, and brewed—and ultimately, how it tastes.

Why Arabica Is King: Flavor, Altitude, and Care

Arabica (Coffea arabica) makes up over 70% of the world’s coffee production. It grows best at higher elevations—typically above 900 meters—such as in Central and South America, East Africa, Southeast Asia, Hawaii, and other tropical highland regions.

These conditions produce Arabica’s signature complex flavors: bright acidity, floral and fruity notes, and a generally pleasant aroma. But those qualities come at a cost. Arabica plants require stable temperatures, careful cultivation, and are sensitive to pests and climate shifts. That sensitivity, along with the difficulty of high-altitude farming, drives up both price and quality potential.

Within Arabica, there are numerous cultivars and varieties, such as:

• Bourbon – an old, respected variety known for balanced sweetness and body
• Typica – one of the earliest cultivated Arabica varieties, often used as a baseline
• Catuai and Catuaí – high-yield, disease-resistant hybrids with good cup quality
• Sumatra – a unique local type grown only on the island of Sumatra
• Ethiopian landraces – traditional, region-specific varieties that form the genetic basis of many modern Arabicas

Many producing countries plant a mix of varieties within a single farm or cooperative, then blend the harvested cherries to create complex regional profiles. For example, Ethiopia’s coffee genetic diversity is unmatched, and many of today’s sought-after specialty varieties trace back to Ethiopian heirloom types.

Robusta: Bitter, Caffeinated, and Hardy

Robusta (Coffea canephora) is much easier to grow and more resilient than Arabica. It thrives at lower altitudes—between 200 and 600 meters—and demands minimal care. It’s also far more resistant to pests and diseases, thanks to its higher caffeine content: 2 to 3 times that of Arabica.

But that toughness comes at a flavor cost. Robusta beans typically produce a harsh, bitter cup with earthy, rubbery, or burnt rubber notes. Its strong, bitter profile makes it common in instant coffee and some commercial blends, especially where cost outweighs cup quality. That said, when expertly handled, certain Robustas can add body and crema to espresso blends.

Other Coffee Species: What About Liberica and Excelsa?

Beyond Arabica and Robusta, two other species appear occasionally in specialty and regional markets:

• Liberica (Coffea liberica) – Grown mostly in Southeast Asia, it has a unique smoky, woody flavor and an irregular bean shape. It makes up less than 1% of global production.
• Excelsa (often classified under Liberica or as a subspecies) – Known for tart, fruity profiles, it grows mainly in Southeast Asia and is sometimes used to add complexity to blends.

These species are rarely seen in mainstream coffee shops but may appear in niche offerings or traditional markets. Most commercial coffee—especially specialty-grade—still comes from either Arabica or Robusta.

Frequently Asked Questions

What are the main types of coffee species?

The five main coffee species are Arabica, Robusta, Liberica, Excelsa, and various lesser-known wild types. Arabica and Robusta make up over 99% of global production, with Arabica alone accounting for more than 70% due to its preferred flavor profile.

Why is Arabica more popular than Robusta?

Arabica is more popular because it has a sweeter, more complex flavor with higher acidity and aromatic qualities. It’s grown at higher altitudes and is more delicate, which increases production costs but results in a more desirable cup for specialty coffee drinkers.

What’s the difference between Arabica and Robusta?

Arabica grows at higher altitudes, has a smoother, more nuanced flavor with notes of fruit and flowers, and contains less caffeine. Robusta grows at lower altitudes, is hardier and more pest-resistant, has a harsh, bitter taste, and contains 2–3 times more caffeine than Arabica.

Does altitude affect coffee flavor?

Yes. Higher-altitude regions (like those where Arabica is grown) tend to produce slower-maturing coffee cherries with more complex sugars and acids, resulting in brighter, more nuanced flavors. Lower-altitude coffees (like Robusta) usually have stronger, simpler, and more bitter profiles.

Are there other coffee species besides Arabica and Robusta?

Yes, but they’re rare. Liberica and Excelsa are occasionally found in traditional or regional markets. Liberica has a smoky, woody flavor and irregular beans, while Excelsa offers tart, fruity notes. Neither plays a major role in the global specialty market.
