Understanding the World’s Two Most Popular Coffee Beans
When people talk about coffee, they’re often referring to one of two bean varieties: Arabica or Robusta.
Together, these two species account for almost all coffee consumed worldwide.
While they may look similar at first glance, Arabica and Robusta are remarkably different in terms of flavour, aroma, growing conditions, caffeine levels and quality.
Understanding the differences between these beans can help you appreciate why speciality coffee shops such as Bocca Felice carefully select the beans they use.
In this guide, we’ll explore everything you need to know about Arabica and Robusta coffee and explain why bean selection plays such an important role in creating exceptional coffee.
What Is Arabica Coffee?
Arabica coffee, scientifically known as Coffea Arabica, is the most popular coffee species in the world.
It accounts for approximately 60-70% of global coffee production.
Arabica originated in Ethiopia and is widely regarded as producing the highest-quality coffee available.
Arabica beans are commonly associated with:
Smooth flavour
Natural sweetness
Complex aroma
Bright acidity
Distinct tasting notes
Speciality coffee shops overwhelmingly favour Arabica beans because of their superior flavour characteristics.
What Is Robusta Coffee?
Robusta coffee, scientifically known as Coffea Canephora, is the second most widely cultivated coffee species. Robusta is generally easier to grow and more resistant to pests and disease than Arabica. It thrives at lower altitudes and in warmer climates.
Robusta is commonly associated with:
Strong flavour
Higher bitterness
Earthy characteristics
Heavier body
Higher caffeine content
While Robusta has traditionally been viewed as lower quality, some high-quality Robustas are increasingly being used in speciality coffee blends.
The Difference in Flavour
The most noticeable difference between Arabica and Robusta is flavour.
Arabica Flavour Profile
Arabica coffees are known for their complexity and balance.
Common tasting notes include:
Chocolate
Smooth cocoa flavours are frequently found in Brazilian and Colombian coffees.
Caramel
Many medium-roast Arabica coffees develop rich caramel sweetness.
Fruit
Berry, citrus and stone fruit flavours are common in African coffees.
Floral Notes
Jasmine and tea-like aromas often appear in Ethiopian coffees. Arabica’s complexity is one of the main reasons it dominates the speciality coffee market.
Robusta Flavour Profile
Robusta generally delivers:
Stronger bitterness
Earthy flavours
Woody notes
Nutty characteristics
Less sweetness
Some consumers enjoy Robusta’s bold profile, particularly in traditional Italian espresso blends.
However, many speciality coffee drinkers prefer Arabica’s greater depth and balance.
Which Bean Contains More Caffeine?
One of the biggest differences between Arabica and Robusta is caffeine content.
Arabica
Typically contains:
1.2-1.5% caffeine
Robusta
Typically contains:
2.2-2.7% caffeine
This means Robusta often contains nearly twice as much caffeine as Arabica.
The higher caffeine content acts as a natural defence mechanism against insects and disease.
This also contributes to Robusta’s stronger bitterness.
Growing Conditions
The environment in which coffee is grown significantly influences quality. Arabica Growing Conditions
Arabica requires:
Higher elevations
Cooler temperatures
Stable climates
Greater care and attention
Typical growing altitudes:
900-2,200 metres above sea level
These challenging conditions help produce more complex flavour profiles.
Robusta Growing Conditions
Robusta is much hardier.
It thrives in:
Lower altitudes
Higher temperatures
More humid environments
Typical growing altitudes:
Sea level to 900 metres
Because Robusta is easier to cultivate, it is often less expensive to produce.
Why Is Arabica More Expensive?
Several factors contribute to Arabica’s higher cost.
