How Many Coffee Bean Varieties Exist Worldwide?

You’ve seen bags labeled ‘Arabica’ and ‘Robusta,’ but have you ever wondered just how many actual coffee bean varieties exist around the world? Whether you’re curious about what grows in Ethiopia or why some beans taste wildly different, the answer starts with understanding the sheer diversity of the coffee plant itself.

Worldwide, there are more than 70 identified coffee species. Of those, only around three to five are commonly cultivated in China, with global commercial production focused on just two: Arabica and Robusta.

What Are the Main Coffee Species Grown Around the World?

Coffee plants fall under the genus Coffea, and more than 70 species have been documented. However, the coffee industry revolves primarily around two: Coffea arabica (Arabica) and Coffea canephora (Robusta). A third, Coffea liberica (Liberica), also exists but is far less common. These three species make up nearly all coffee consumed globally, with Arabica leading in specialty markets due to its preferred flavor profile.

Which Coffee Varieties Are Grown in China?

In China, coffee cultivation focuses on a small selection of species suited to local climates. The primary ones include:

• Small-Bean Variety (Coffea arabica, Typica-like): Also called 'Arabic coffee' or ',' this is the classic Arabica type originally from Ethiopia. It’s grown in Taiwan, Fujian, Guangdong, Guangxi, Yunnan, and Sichuan in China. Plants reach 4–6 meters, with high branches, thin leaves, and either green or bronze-tipped young shoots (earning them nicknames like 'Green Top' and 'Red Top'). The cherries are small, thick-skinned, and relatively easy to process. This variety is aromatic, moderate in yield, cold- and drought-resistant—but prone to disease.
• Medium-Bean Variety (Coffea canephora, Robusta-like): Known as '' or ',' this is the robusta-type coffee native to the Congo rainforest. It thrives at low elevations within 10° latitude north and south, mainly in Southeast Asia. In China, it’s grown on Hainan Island, with limited past cultivation in Xishuangbanna, Yunnan. It’s a small evergreen tree (5–8 meters), with large, thick leaves. Fruits are flat or oval, turning purple-red when ripe. The bean is bold, with thin fruit and seed coatings that stick together. This variety resists pests well but doesn’t tolerate wind or drought. Its cup is bold, bitter, and highly stimulating.
• Large-Bean Variety (Coffea liberica, Liberica): Called '' or ',' it originates from Liberia’s lowland forests. It’s planted at low elevations in tropical zones and is rarely grown outside of West Africa. In China, it’s found only in small plots on Hainan. The trees grow up to 10 meters with broad leaves. The cherries are very large, light red when ripe, with thick, tough skins and pulp. The plants have deep roots, resist drought and wind, and tolerate cool better than other species—but are highly vulnerable to leaf rust. The cup profile is strong, harsh, and generally considered lower quality.

Why Do Only Two Coffee Species Dominate the Global Market?

Despite dozens of coffee species existing, just two dominate the international coffee trade: Arabica (Coffea arabica) and Robusta (Coffea canephora). Here’s why:

• Arabica beans are elongated, flatter, and typically deeper green. They thrive in cooler, seasonal climates of 15–24°C and at higher altitudes—between 800 and 2000 meters. Arabica is prized for its complex acidity, sweetness, and aromatic qualities. It’s more susceptible to pests and diseases, especially leaf rust, and requires volcanic soils rich in nutrients. Arabica commands higher market prices and is the foundation of specialty coffee.
• Robusta beans are rounder, thicker, and lighter in color. They grow in warmer, stable equatorial climates (24–29°C) and at lower altitudes—around 500 meters. Robusta offers stronger bitterness, higher caffeine content, and more intense body. It resists pests better than Arabica but is more vulnerable to cold. Because of its strong flavor and lower cost, Robusta is widely used in instant coffee and espresso blends for crema and body enhancement.

Both species need consistent sunlight, water, and well-drained, fertile soil. Altitude plays a crucial role: Arabica performs best at elevation, where temperatures are moderate, while Robusta thrives in hotter, lowland conditions. Volcanic soils are ideal for both, supplying essential minerals.

What Determines Coffee Plant Survival and Cup Quality?

Several environmental factors dictate where coffee can be grown and how it tastes:

• Temperature: Arabica prefers 15–24°C; Robusta needs 24–29°C year-round.
• Altitude: Arabica grows best at 800–2000 meters; Robusta at around 500 meters.
• Soil: Volcanic soils are optimal, offering rich nutrients and good drainage.
• Moisture & Rainfall: Both require ample, well-distributed rainfall without extreme dry spells.
• Disease Resistance: Arabica is vulnerable to leaf rust and other pathogens; Robusta has stronger natural resistance but lower cup complexity.

These variables influence not just survival, but also the flavor, aroma, body, and acidity of the brewed coffee.

Frequently Asked Questions

How many coffee bean species exist in the world?

More than 70 coffee species have been identified scientifically, though only a fraction are cultivated commercially. The vast majority of these species are wild or grown in very limited regions and not used in mainstream coffee production.

What are the two main coffee species in the global market?

The two primary coffee species are Arabica (Coffea arabica) and Robusta (Coffea canephora). Arabica makes up most specialty coffee and is valued for its flavor complexity, while Robusta is more bitter, higher in caffeine, and mostly used in commercial and instant coffee.

Which coffee species are grown in China?

In China, the cultivated species include the small-bean Arabica type (commonly grown in Yunnan and other southern provinces), the medium-bean Robusta-like variety (mainly on Hainan), and a very limited amount of the large-bean Liberica coffee (also on Hainan). Only three to five species are commonly grown domestically.

Why is Arabica more popular than Robusta in specialty coffee?

Arabica is favored in specialty coffee for its nuanced flavors, brighter acidity, and aromatic complexity. It grows at higher altitudes, develops slower, and generally has a more desirable cup profile—though it’s also more delicate and prone to disease compared to Robusta.

What’s the difference between Arabica and Robusta beans visually?

Arabica beans are typically longer, flatter, and darker green, with an oval shape. Robusta beans are rounder, thicker, and lighter in color. These physical differences reflect their distinct growing conditions and processing results.

Can coffee grow in low-altitude regions?

Yes, but mainly Robusta and Liberica species are suited to low-altitude cultivation (around 500 meters). Arabica requires higher altitudes (800–2000 meters) for optimal flavor development and disease resistance.
