Coffee Species, Trees, and How Coffee Is Grown

When you sip your morning coffee, you’re almost certainly drinking either Arabica or Robusta beans—but how did those two species come to dominate the market? And why are some coffees smooth and complex while others are bitter and harsh? The answer starts with plant biology, geography, and a history of agricultural struggle.

In short: there are over 100 coffee species, but only two—Arabica and Robusta—are widely grown commercially. Arabica makes up around 60–70% of global production, while Robusta, which is hardier and more bitter, fills the rest—especially in instant coffee. Other species exist, but most are rare or not economically viable.

The Origins of Coffee Species: Arabica vs Robusta

Originally, nearly all cultivated coffee was Arabica. But in the 19th century, a wave of pests and diseases devastated Arabica farms. That crisis pushed farmers to seek alternatives—and they found Robusta. First discovered and cultivated in the Congo region, Robusta (Coffea canephora) was scientifically named and introduced to commercial agriculture as a more resilient species.

Robusta grows well at low altitudes, withstands both cold and drought, and resists pests far better than Arabica. In one word: it’s “tough.” But that toughness comes at a cost. Robusta beans produce a harsher, more bitter cup with about twice the caffeine of Arabica—around 2.7% compared to Arabica’s 1.2–1.5%. That extra caffeine is a natural pest deterrent, but it also contributes to the bitter taste. Because of its lower cup quality, Robusta is usually cheaper and is the primary bean used by most instant coffee producers.

Major Coffee-Producing Countries

Coffee is grown in more than 50 countries, but just a few dominate global supply. Brazil is the largest coffee exporter in the world, followed closely by Colombia—both located in South America. Together, these two countries produce more than half of the world’s coffee, and their output is known for consistent quality.

Vietnam has risen rapidly in recent decades and at one point became the world’s second-largest coffee exporter. Other well-known coffee origins include Indonesia, Ethiopia, Guatemala, Jamaica, and Kenya. Each of these regions offers unique flavour profiles due to differences in climate, altitude, and processing methods.

Coffee in China: Yunnan and Hainan

Though often overlooked, China does grow coffee—primarily in Yunnan and Hainan provinces. The country’s coffee industry faces challenges from soil conditions, climate limitations, and gaps in technical farming and management practices. As a result, Chinese-grown beans have historically received little international attention.

That began to change in late 2008, when Starbucks launched a limited-edition blend called “Feng Wu Xiang Yun” (“Phoenix Dancing in the Clouds”) to celebrate its 10th anniversary in the Chinese market. Though only 10% of the blend came from Yunnan, the release marked a milestone: for the first time, Yunnan-grown coffee entered the supply chain of the world’s largest coffee retailer. It was a small percentage, but a significant moment for China’s coffee industry.

What Determines Coffee Quality?

Coffee quality depends on multiple factors: the species (Arabica vs Robusta), the growing altitude, climate, soil, processing method, and roast level. Arabica grown at higher altitudes (1,200–2,000 metres) generally produces a more complex, acidic, and nuanced cup. Robusta, grown at lower altitudes, is more bitter and less aromatic.

Processing—whether the beans are washed, natural, or honey-processed—also plays a major role in defining flavours. And finally, roast level affects how those inherent flavours are expressed or muted.

Frequently Asked Questions

What are the two main types of coffee beans?

The two main commercial coffee species are Arabica and Robusta. Arabica is known for its smoother, more complex flavours and lower caffeine content, while Robusta is harsher, more bitter, and contains roughly twice the caffeine. Arabica accounts for about 60–70% of global production, with Robusta making up the rest.

Where is most of the world’s coffee produced?

The majority of the world’s coffee comes from Brazil and Colombia, which together export over half of all global coffee. Vietnam is another major producer and was once the second-largest exporter. Other notable coffee-growing countries include Ethiopia, Guatemala, Indonesia, Jamaica, and Kenya.

Does China grow coffee?

Yes, China grows coffee, mainly in Yunnan and Hainan provinces. Despite challenges like soil, climate, and farming techniques, Yunnan coffee gained some international recognition in 2008 when Starbucks included 10% Yunnan beans in a special blend celebrating its 10th year in China.

Why is Robusta cheaper than Arabica?

Robusta is cheaper because it is easier and cheaper to grow—it resists pests and diseases, survives at low altitudes, and needs less care. However, it produces a more bitter cup and is usually used in instant coffee or as a cheap filler in commercial blends. Its higher caffeine content also contributes to its harsher taste.

What’s the difference between Arabica and Robusta in taste?

Arabica tends to have a sweeter, more acidic, and complex flavour profile with notes of fruit, sugar, and floral or wine-like qualities. Robusta is stronger, harsher, and more bitter, with earthy or nutty flavours and a heavier body. Arabica is generally considered higher quality for specialty coffee.

What altitude is best for growing coffee?

The best altitude for growing high-quality Arabica coffee is typically between 1,200 and 2,000 metres above sea level. At these heights, coffee develops more slowly, leading to denser beans with more complex flavours. Robusta grows better at lower altitudes, usually below 1,000 metres.
