The 5 Main Coffee Species Classified by Chinese Standards

If you’ve ever wondered why some coffees taste bright and nuanced while others are bold and bitter, part of the answer lies in the species of the coffee plant itself. With over 60 known coffee species, commercial production focuses on just a few—but how are they actually classified? The answer isn’t always straightforward, especially when looking at national standards.

Under China’s national coffee classification system, coffee is officially divided into five main species: Arabica , Robusta , Liberica , Excelsa , and a hybrid called Arabusta . These categories reflect differences in origin, growing conditions, flavor, and resistance to disease.

What Is Arabica Coffee? The World’s Favorite Coffee Species

Arabica coffee—known as or 'small-seed' coffee—is the most widely cultivated coffee species in the world, covering around 70% of global coffee-growing areas. Native to Ethiopia, it’s grown in regions like Yunnan and Guangdong’s Zhanjiang in China. Arabica plants tolerate cooler temperatures and drought better than other species, producing a cup that’s aromatic and well-balanced. However, they are highly susceptible to coffee leaf rust .

What About Robusta? The Bold and Bitter Counterpart

Making up approximately 30% of global cultivation, Robusta—called or 'medium-seed' coffee—is native to the tropical rainforests of the Congo in Africa. In China, it is primarily grown in Hainan. Unlike Arabica, Robusta thrives in warmer, more humid, and lower-altitude environments. It’s much hardier, resisting diseases like leaf rust, but it produces a harsher, more bitter cup with stronger caffeine content and less nuanced flavor. Robusta is less sensitive to sunlight, wind, and drought, but its flavor profile is often described as earthy and intense.

The Other Coffee Species: What You Need to Know

Beyond Arabica and Robusta, China’s national classification includes three more coffee species:

• Liberica : Originating from Liberia in West Africa, this species is rarely cultivated. It grows best in low-altitude, hot climates and is planted in small amounts in Hainan, China. Its market share is minimal compared to Arabica and Robusta.
• Excelsa : Native to the Chari River basin in West Africa, Excelsa is not cultivated in China. It is sometimes considered a subspecies of Liberica, though it has distinct characteristics.
• Arabusta : A man-made hybrid developed in 1962 by the French Coffee and Cocoa Research Institute. It results from crossing tetraploid Robusta with Arabica using colchicine. Arabusta was created in Côte d’Ivoire and is not grown in China. It was bred for improved disease resistance and adaptability, but hasn’t achieved widespread commercial use.

Which Coffee Species Grows Best in China?

According to the article, the most suitable coffee species for cultivation in China’s Yunnan region is Arabica . Its ability to tolerate cooler temperatures and resist some environmental stresses makes it the preferred choice for Chinese coffee growers, particularly in Yunnan province, which has become a major specialty coffee origin in recent years.

Frequently Asked Questions

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

The five coffee species classified under China’s national standards are: Arabica , Robusta , Liberica , Excelsa , and Arabusta . These categories cover the primary types grown or studied in China, with Arabica and Robusta being the most common.

What is the most widely grown coffee species in the world?

Arabica is the most widely grown coffee species, accounting for around 70% of the world’s coffee production. It originates from Ethiopia and is valued for its balanced, aromatic cup profile, though it is vulnerable to coffee leaf rust.

Which coffee species is known for being strong and disease-resistant?

Robusta is known for its strong, bitter flavor and high caffeine content. It is more resistant to diseases like leaf rust and can grow in harsher conditions, but it makes up about 30% of global production due to its more bitter taste.

Is Liberica coffee commonly grown or consumed?

No, Liberica is rarely grown or consumed. It originates from Liberia and is difficult to cultivate, with minimal global production and almost no presence in China’s coffee industry.

Are there any hybrid coffee species grown in China?

Arabusta is a hybrid coffee species developed in Côte d’Ivoire by crossing Robusta and Arabica. It was bred for disease resistance but is not cultivated in China. Other hybrids may exist globally, but they are not part of China’s five official classifications.
