Coffee Plant Types: What You Need to Know

When you take your first sip of coffee in the morning, you're likely enjoying the work of a plant — but not just any plant. Behind every cup are thousands of decisions made by farmers, scientists, and roasters about what kind of coffee plant produced those beans. If you’ve ever wondered how many types of coffee plants exist and which ones end up in your brew, you’re not alone. This article breaks down the real botanical classification of coffee plants, with exact numbers and key details you won’t find in a menu.

In total, there are over 60 known coffee species, but only two — Arabica and Robusta — make up nearly all commercial production: Arabica accounts for roughly 70% of global coffee cultivation, while Robusta covers about 30%. These two species, along with three others officially recognised in China, form the foundation of the world’s coffee supply.

What Is Coffee, Botanically Speaking?

From a botanical perspective, coffee is defined as “a perennial evergreen shrub or small tree belonging to the Rubiaceae family, genus Coffea.” This classification places it in the same broad plant family as gardenias and quinine, but the genus Coffea contains dozens of species, only a handful of which are cultivated for coffee consumption.

The Big Two: Arabica and Robusta

Globally, coffee farming focuses overwhelmingly on just two species. Arabica (Coffea arabica), often referred to as in Chinese (meaning ‘small-bean variety’), makes up about 70% of the world’s coffee farms. It’s prized for its balanced flavours, aromatic complexity, and relatively delicate cup — though it’s more susceptible to pests like leaf rust. Robusta (Coffea canephora), or (‘medium-bean variety’), accounts for the remaining 30%. It’s hardier, less prone to disease, and produces a stronger, more bitter cup with higher caffeine content, but it lacks the refined profile of Arabica.

How China Classifies Coffee Varieties

According to the Chinese national standard, coffee is divided into five distinct varieties:

• Small-bean variety — Also known as Arabica or . Originating in Ethiopia, it’s the most widely grown coffee type in the world. In China, it’s mainly cultivated in Yunnan and Guangdong’s Zhanjiang region. It tolerates cooler temperatures and drought better than other types, produces a fragrant and high-quality cup, but is highly vulnerable to leaf rust disease.
• Medium-bean variety — Commonly called Robusta or . Originally from the tropical rainforests of the Congo in Africa, it’s the second-most planted species globally. In China, it’s primarily grown in Hainan. This variety doesn’t handle strong sunlight, wind, drought, or cold well, but it resists diseases effectively, especially leaf rust, and delivers a bold, intense flavour.
• Large-bean variety — Known as Liberica or . Native to Liberia in Africa, it’s rarely cultivated. In China, small plantings exist in Hainan. It thrives in low-altitude, hot regions.
• Ethiopian variety — Originating from the Chari River basin in West Africa. Not cultivated in China.
• Arabusta hybrid — 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 treatment. This variety is not grown in China.

Which Coffee Variety Grows Best in China?

Among all these, the small-bean (Arabica) variety is considered the most suitable for cultivation in China, especially in Yunnan — the country’s primary coffee-growing region. Its ability to withstand cooler temperatures and some drought, combined with its premium cup quality, makes it the preferred choice for Chinese coffee farms.

More Than Just Arabica and Robusta

While Arabica and Robusta dominate the market, the lesser-known species — Liberica, Ethiosar, and the hybrid Arabusta — represent the full genetic range of the Coffea genus. Though most are not commercially viable today, they play a role in coffee’s botanical diversity and historical development. Even within Arabica, countless cultivars and regional adaptations exist, contributing to the wide spectrum of flavours found in your cup.

Frequently Asked Questions

How many coffee species are there in total?

There are over 60 known species of coffee, though only a few are commercially cultivated. Most come from the Coffea genus in the Rubiaceae family.

Which two coffee species make up most of the world’s coffee production?

Arabica accounts for about 70% of global coffee production, while Robusta makes up approximately 30%. These two species dominate the coffee industry.

What is the small-bean coffee variety?

The small-bean variety, also known as Arabica or , originates from Ethiopia. It’s widely grown around the world, especially in high-altitude regions, and is known for its aromatic, high-quality flavour, though it’s susceptible to leaf rust.

What is the medium-bean variety?

The medium-bean variety, or Robusta , comes from the African Congo rainforest. It’s hardier than Arabica, more resistant to disease, but produces a stronger, more bitter cup with higher caffeine levels.

Which coffee variety is best suited to grow in China?

The small-bean (Arabica) variety is considered the most suitable for China’s growing conditions, particularly in Yunnan province, where the climate and altitude support its cultivation.
