Types of Coffee Trees and What They Mean for Your Cup

If you’ve ever wondered why some coffee tastes bright and fruity while others are bold and bitter, the answer starts with the tree. There are at least 12 known species of coffee plants, but only two make up nearly all the coffee you drink. What defines these trees—and how do they shape your morning brew? Here’s what every coffee drinker should know.

Only two coffee tree species—Arabica (Coffea arabica) and Canephora (Coffea canephora, commonly called Robusta)—account for over 99% of global coffee production. Arabica makes up 70%+ of the market, while Canephora covers just under 30%. The other 10 species (like Liberica, Excelsa, and Dewevrei) are either rarely grown or unused in commercial coffee.

The Biology of Coffee Trees

Coffee trees belong to the kingdom Plantae, phylum Magnoliophyta, class Magnoliopsida, order Gentianales, family Rubiaceae, and genus Coffea. That’s the scientific lineage—but what matters to drinkers is how this genus splits into usable (and mostly unusable) species. Most coffee trees naturally grow tall—up to three meters—but in farms, growers prune the tops once the trees hit that height. This keeps them shorter and easier to harvest by hand.

Arabica vs. Canephora: The Core Two

Practically, the coffee world revolves around two species derived from the main types: Arabica (from Coffea arabica, once called “small-bean coffee”) and Robusta (from Coffea canephora, once “medium-bean coffee”). These two are planted in different regions, develop unique flavors, and require distinct processing. Knowing their differences is the foundation of understanding quality coffee.

Arabica: The Global Favorite

Arabica coffee comes from Coffea arabica, originally native to Ethiopia. It dominates the market with over 70% global production. These trees thrive in cooler, high-altitude environments—between 800 to 2,000 meters above sea level—and prefer temperatures from 15°C to 25°C. Arabica plants demand well-drained, fertile soil (volcanic soils are ideal) and indirect sunlight. In regions like Yunnan, where cloud cover is common, farmers skip shade planting and still achieve strong yields. The beans are known for delicate, nuanced flavors: think fruit, nuts, chocolate, and floral notes. Arabica is usually more expensive due to its preferred taste profile and more delicate growing needs.

Canephora (Robusta): Strong and Stark

Canephora, known as Robusta in the cup, hails from the Congo and makes up under 30% of global coffee. These trees grow in hotter lowland areas (24°C to 29°C) and at lower altitudes than Arabica. They tolerate direct sun, resist pests better, and produce higher yields. But the trade-off is flavor: Robusta beans often taste harsh, earthy, or even rubbery, with a heavier body and more bitterness. While Robusta has long been dismissed as inferior, carefully selected beans can surprise with strong, bold profiles. It’s commonly used in espresso blends for added crema and caffeine kick—or in budget blends. Its lower market price reflects its reputation, though not always its potential.

Liberica, Excelsa & the Forgotten Species

Beyond Arabica and Canephora lie eight other species: Liberica, Excelsa, Dewevrei, Khasiana, Arnoldiana, Abeokutae, Wightiana, Bengalensis, Travencorensis, Racemosa, Salvatrix, Congensis, Kapakata, Stenophylla, and Eugenioides. Most are untouched for commercial coffee and grow wild, mainly in Ethiopia’s rainforests, where the government protects them. Among them, Liberica (the so-called “large-bean coffee” from Liberia) is occasionally cultivated in Malaysia but rarely seen in global markets due to its unappealing taste. Excelsa (sometimes classified separately) also falls outside the mainstream. Many of these species remain untapped resources for future coffee innovation—if breeders can unlock their potential.

Growing Conditions Dictate Flavor

Where a coffee tree grows shapes not just its survival, but your cup’s flavor. Arabica thrives in cooler highlands with filtered light and rich volcanic soil. Shade-grown Arabica (on the “shady side” of mountains or intercropped with bananas) often yields sweeter, more complex beans—even if the effect is subtle. In contrast, Robusta loves heat, full sun, and lowland fields. These environmental differences don’t just affect yield—they change the chemical compounds in the beans, leading to dramatically different tastes after roasting.

Flavor Profiles: Why It Matters

Arabica beans produce bright, nuanced cups: think citrus, berries, stone fruit, caramel, or floral hints. The variety of flavors makes Arabica ideal for single-origin offerings and specialty brewing methods. Robusta, meanwhile, tends toward harsh, bitter, and earthy profiles—with notes some describe as rubbery or burnt. That’s why Arabica commands higher prices and is favored for pour-over, Aeropress, and even high-end espresso. Yet in traditional Italian espresso blends, Robusta is often added for body and crema. Your brewing method, roast level, and origin all interact with these base flavors—so knowing whether your beans are Arabica or Robusta is the first step to understanding your coffee.

Frequently Asked Questions

What are the main species of coffee trees used for drinking coffee?

Only two species are widely used for commercial coffee production: Coffea arabica (Arabica) and Coffea canephora (Robusta/Canephora). Arabica accounts for over 70% of global production, while Canephora makes up under 30%. The other known species (like Liberica, Excelsa, and 10 more) are either rarely grown or not used for making drinkable coffee.

Why is Arabica more popular than Robusta?

Arabica is valued for its smoother, more complex flavors—often featuring fruit, nuts, chocolate, or floral notes. It grows best in cooler, high-altitude regions and is more sensitive to growing conditions. Robusta, while stronger and more bitter, is hardier, pest-resistant, and grows at lower altitudes, but its harsher profile has historically made it less desirable. However, top-quality Robusta can still surprise coffee experts.

What’s the difference in growing conditions for Arabica and Robusta?

Arabica prefers altitudes of 800–2,000 meters, temperatures of 15–25°C, and indirect sunlight. It thrives in fertile, often volcanic soils and is often shade-grown. Robusta grows at lower altitudes (typically below 1,000 meters), tolerates warmer temperatures (24–29°C), and thrives in full sun. It also resists pests better and requires less maintenance.

Are there other coffee tree species besides Arabica and Robusta?

Yes, there are at least 10 other known species, including Coffea liberica (Liberica), Coffea excelsa (Excelsa), Coffea dewevrei, and several others. Most are not used for commercial coffee production and are either wild or grown in limited regions like Ethiopia. Some, like Liberica, are occasionally cultivated but have niche or poor flavor appeal.

Does the coffee tree type affect the flavor of my cup?

Absolutely. Arabica beans generally produce bright, nuanced flavors suited for specialty coffee. Robusta beans tend to be harsher, more bitter, and earthy. Even within species, origin, altitude, and processing change the cup profile—but the tree species sets the baseline for taste, aroma, and body.
