The Five Main Coffee Species by Botanical Classification

When you take a sip of your favorite cup of coffee, have you ever wondered what exact plant it came from? While dozens of coffee plants exist in nature, not all make it to your cup—and not all are created equal. So, what are the real, commercially and botanically recognized types of coffee plants, and where do they come from?

According to Chinese national standards, there are five officially recognized coffee species: Arabica (small-seed), Robusta (medium-seed), Liberica (large-seed), Excelsa (also called Ethereal), and Arabusta (a hybrid). But only three—Arabica, Robusta, and Liberica—are widely known, while the others are rare or not cultivated in China at all.

What Is Coffee, Botanically Speaking?

Coffee is classified botanically as a perennial evergreen shrub or small tree in the genus Coffea, family Rubiaceae. This classification covers all coffee plants—but not all plants in this genus produce the beans we roast and brew. Within Coffea, just a few species dominate global coffee production.

The Five Official Coffee Species in China

Under the Chinese national standard system, coffee is divided into five primary varieties:

• 1. Small-seed Coffee (Arabica): Also known as Arabian coffee. Originally from Ethiopia, this is the most widely grown coffee in the world, covering about 70% of global production. In China, it’s mainly planted in Yunnan and the Zhanjiang area of Guangdong. It tolerates cold and drought relatively well, produces aromatic and high-quality cups, but is highly susceptible to leaf rust disease.

  

• 2. Medium-seed Coffee (Robusta): Commonly called Robusta. Originally from the tropical rainforests of the Congo in Africa, it’s the second-most cultivated species, making up around 30% of global production. In China, it’s primarily grown in Hainan. Robusta doesn’t tolerate strong light, wind, drought, or cold well, but it resists disease effectively—including leaf rust—and creates a bold, more bitter cup.
• 3. Large-seed Coffee (Liberica): Originating from Liberia in Africa, this variety is rarely cultivated globally. In China, it’s found in limited amounts in Hainan. It thrives in low-altitude, hotter regions but is not widely adopted due to its specific growing needs and smaller market presence.
• 4. Excelsa (Ethereal Coffee): From the Chari River basin in West Africa. This species is not cultivated in China. It’s less common in the global market and not a major commercial variety.
• 5. Arabusta: A man-made hybrid developed in 1962 by the French Coffee and Cocoa Research Institute. It resulted from crossing tetraploid Robusta with Arabica using colchicine. This variety is also not grown in China. It was bred to combine traits of both species but hasn’t seen widespread adoption.

Which Coffee Species Grows Best in China?

In China, the most suitable coffee species for cultivation is Arabica (the small-seed variety). Yunnan province, in particular, provides ideal conditions for Arabica, which accounts for nearly all of the country’s specialty coffee production. Other species like Robusta are grown in Hainan, but they occupy a much smaller share of both planting area and market relevance.

Why These Five Species?

The division into these five species reflects both botanical differences and practical farming considerations in the Chinese context. While over 60 coffee species exist in nature, only these five have been officially categorized within China’s national standards. Of those, just Arabica, Robusta, and Liberica are grown—each selected for climate adaptability, disease resistance, and cup quality in local conditions.

Frequently Asked Questions

What are the five official coffee species according to Chinese standards?

The five recognized coffee species in China are: Arabica (small-seed), Robusta (medium-seed), Liberica (large-seed), Excelsa (Ethereal), and Arabusta (a hybrid). Only the first three are grown in any significant capacity, with Arabica being by far the most common and suitable for China’s conditions.

Which coffee species makes up 70% of the world’s coffee?

Arabica, also known as the small-seed or Arabian coffee, accounts for approximately 70% of global coffee cultivation. It originated in Ethiopia and is prized for its cup quality, though it is vulnerable to leaf rust.

What is Robusta coffee, and where is it grown in China?

Robusta, or medium-seed coffee, makes up about 30% of the world’s coffee. It’s mainly grown in Hainan, China. It’s hardier than Arabica, resistant to rust, but produces a stronger, more bitter brew and is less popular for specialty coffee.

Is Liberica coffee grown in China?

Yes, Liberica (large-seed coffee) is grown in very small amounts in Hainan, China. It originated in Liberia, Africa, and is suited to hot, low-altitude regions, but it isn’t widely cultivated anywhere due to limited demand and specific growing needs.

Does China grow the Arabusta hybrid coffee?

No, China does not cultivate Arabusta, which is a hybrid created in 1962 by crossing Robusta and Arabica using colchicine. It was developed in the Ivory Coast but hasn’t been adopted in China or elsewhere at scale.
