Main Coffee Bean Varieties Explained

Ever wondered what coffee shops mean when they say they use 'Arabica' or promote 'Blue Mountain'? With so many terms thrown around—Arabica, Robusta, Yirgacheffe, Mandheling, even 'cat poop coffee'—it’s hard to know what you’re really getting. This guide breaks down the major coffee bean types, their origins, flavour profiles, and what makes each unique.

In short, the two main coffee species are Arabica (grown above 1,200m, making up 60% of global production) and Robusta (800–1,200m, 40%). But most coffee names—like Jamaican Blue Mountain or Yirgacheffe—refer to specific growing regions, not just species. Quality depends more on origin, processing, and altitude than the broad species label alone.

Two Main Coffee Species: Arabica vs Robusta

Coffee beans fall primarily into two species: Arabica and Robusta. Arabica refers broadly to beans grown at higher elevations, typically above 1,200 metres. These make up around 60% of the world’s coffee production. Robusta, meanwhile, is grown at slightly lower altitudes, between 800 and 1,200 metres, and accounts for the remaining 40%. While some sellers may promote 'Arabica' as a sign of quality, it’s not a guarantee—Robusta is still widely used, especially in blends and espresso for its strong, bitter kick and higher caffeine content.

Regional Coffee Varieties and Their Profiles

Most coffee is named after its place of origin rather than just its species. These regional varieties have distinct flavours shaped by climate, soil, and altitude. Major coffee-growing regions include South America, Africa, and Southeast Asia.

Africa: The Birthplace of Coffee

Africa is where coffee originated, and it remains home to a wide diversity of bean types. Two well-known African origins are Yirgacheffe and Mojo (also spelled 'Mocha' or 'Moka', likely referring to Mocha Yemen or a local Ethiopian variety).

• Yirgacheffe: Known for its floral aroma and bright acidity, Yirgacheffe is often considered one of Africa’s flagship coffees. It’s a favourite among specialty roasters for its tea-like body and citrus notes.
• Mojo (or Mocha): Famous for its nutty flavour when milk is added, Mojo is sometimes used by commercial chains as a base for flavoured drinks. Its chocolatey profile when mixed with milk led some businesses to replace actual flavouring with chocolate syrup to cut costs.

South America: Big Producers with Distinct Styles

South America produces some of the most recognisable and widely consumed coffees in the world. Key countries include Brazil, Colombia, Jamaica, and Mexico.

• Jamaican Blue Mountain: Perhaps the most famous coffee globally, Jamaican Blue Mountain is celebrated for its mild flavour, pronounced fruit acidity, and elegant aroma. It’s grown at high elevations and is in such limited supply that most of the region’s production is owned or controlled by Japanese interests. Due to its scarcity, authentic Blue Mountain coffee is expensive—around $30 per cup’s worth of beans—so beware of cheap imitations.
• Brazil: The largest coffee producer in the world, Brazil is known for consistent, balanced beans that form the backbone of many commercial and espresso blends.
• Colombia: Colombian coffee is highly regarded, especially for cold brew due to its bright acidity and medium body. However, currency fluctuations have driven up local prices significantly in recent years.
• Mexico: Often producing lower-grade beans, Mexican coffee is sometimes used by major chains despite claims of high quality.

Southeast Asia: Bold and Earthy Profiles

In Southeast Asia, Indonesia is the standout coffee origin, with Mandheling and Java being the most famous varieties.

• Mandheling: Grown in northern Sumatra, Mandheling beans are large with a strong, bold flavour. They often exhibit pronounced sweetness and bitterness, and are usually processed using the wet-hulled (Giling Basah) method, which contributes to their earthy, full-bodied profile.
• Java: A Robusta variety, Java beans are known for their intense bitterness. They’re commonly used in espresso blends, especially those requiring heavy milk, as their strong flavour can hold up against dairy.
• Vietnam: A major producer of low-cost Robusta, much of which is used in commercial settings like fast-food chains.
• Yunnan (China): Both Yunnan and Hainan grow coffee, though most is of average quality and typically used in blends.

The World’s Most Expensive Coffee: Kopi Luwak (Civet Coffee)

Kopi Luwak, also known as civet or 'cat poop' coffee, is made from beans eaten and excreted by civet cats. The beans ferment as they pass through the animal’s digestive system, which some claim reduces bitterness and adds a unique flavour. There are both wild and farmed varieties, with wild-sourced beans considered rarer and more valuable because the animals allegedly select only the ripest cherries. Kopi Luwak can cost over $100 per cup, but many coffee experts argue that its taste doesn’t justify the high price.

Frequently Asked Questions

What is the difference between Arabica and Robusta coffee beans?

Arabica beans are generally grown at higher altitudes (above 1,200m) and make up about 60% of global production. They tend to have a sweeter, more acidic, and complex flavour. Robusta is grown at lower altitudes (800–1,200m), comprises around 40% of production, and has a stronger, more bitter taste with higher caffeine content. 'Arabica' doesn’t always mean high quality—it’s just one species.

What is Yirgacheffe coffee?

Yirgacheffe is a coffee-growing region in Ethiopia known for producing beans with a floral aroma, bright acidity, and tea-like body. It’s considered one of Africa’s premier coffee origins and is highly valued in the specialty coffee market.

What is Jamaican Blue Mountain coffee?

Jamaican Blue Mountain is a famous coffee grown in Jamaica’s Blue Mountains. It’s known for its mild flavour, fruity acidity, and elegant profile. Production is tightly controlled, mostly by Japanese interests, and genuine Blue Mountain coffee is rare and expensive—about $30 per cup’s worth of beans.

What are Mandheling and Java coffee beans?

Mandheling is a high-quality Indonesian coffee from Sumatra, known for its bold, sweet, and sometimes earthy profile. Java refers to Robusta beans from Indonesia that are very bitter and often used in milk-heavy espresso blends.

What is Kopi Luwak or cat poop coffee?

Kopi Luwak is made from coffee beans that have been eaten and excreted by civet cats. The beans ferment in the animal’s gut, which proponents say improves flavour. It’s extremely expensive (over $100 per cup), but many experts feel the taste doesn’t match the price.

Why is Colombian coffee popular for cold brew?

Colombian coffee is often highlighted for cold brew due to its bright acidity and medium body. Its flavour holds up well in cold brewing methods, although recent currency issues have increased its price significantly.
