What are Robusta Coffee Beans?

Robusta coffee beans are one of the two main species of coffee beans grown commercially, the other being Arabica. Robusta (Coffea canephora) accounts for about 45% of all coffee grown worldwide, while Arabica (Coffea arabica) makes up the remaining 55%.

Robusta coffee beans are known for their strong and bold flavors, higher caffeine content, and are typically grown at lower elevations. They are also hardier than Arabica, which means they are easier to grow and can stand up to harsher elements than their counterpart.

Robusta beans have a higher acidity level than Arabica, which can give them a bad rap. However, this acidity level can also give Robusta beans a unique flavor profile that Vienamese coffee drinkers prefer.

Origins of Robusta Coffee Beans

Robusta coffee beans are known for their high caffeine content, strong flavor, and larger bean size compared to Arabica beans.

Geographical Roots

Robusta coffee beans are native to sub-Saharan Africa, specifically the tropical forests around Lake Victoria in Uganda. The coffee plant was first discovered in the Congo during the 1800s by a French botanist named Hippolyte de Bouchard. The coffee plant is a robust species that can grow up to 10 meters high and is more resistant to diseases than Arabica coffee plants.

Historical Context

The cultivation of Robusta coffee expanded beyond its African origins as the global demand for coffee grew. After the coffee rust disease wreaked havoc on Ceylon in 1869 and then wiped out the majority of low-altitude plantations in Java in 1876, Robusta was introduced to Southeast Asia. This hardier plant was integral in the rebirth of coffee growth in these areas.

Today, Vietnam is the largest producer of Robusta coffee, accounting for around 40% of the world’s Robusta production. This significant proportion places Vietnam second only to Brazil in terms of overall coffee production. Other countries that produce Robusta coffee include Brazil, Indonesia, and India.

Characteristics of Robusta Coffee Beans

Robusta coffee beans are known for their uniquely bold characteristics that set them apart from other coffee varieties.

Taste Profile

They are known for their strong, bold, and earthy flavor, with a hint of bitterness. The acidity level in Robusta coffee is higher than that of Arabica coffee, which gives it a sharp taste. The flavor of Robusta coffee is usually described as nutty or chocolaty.

Robusta coffee is also known for its higher caffeine content. It contains almost twice the amount of caffeine as Arabica coffee, making it a popular choice for people who need an extra energy boost.

Physical Attributes

Robusta coffee beans are smaller and more circular in shape than Arabica coffee beans. They have a harder outer layer, which makes them more resistant to pests and diseases.

Robusta coffee plants are hardier and more adaptable to harsher weather conditions, which makes them easier to grow.

Robusta coffee beans are typically grown at lower elevations than Arabica coffee beans. They are also cheaper to produce, which makes them a popular choice for commercial coffee production. However, the lower flavor quality of Robusta coffee beans compared to Arabica coffee beans often gives them a bad reputation.

Coffee Processing Methods

Cultivation and Harvesting

Growing Conditions

Robusta coffee beans are grown in tropical regions with high humidity and rainfall. They require temperatures between 24-30°C and can grow at altitudes up to 760 meters. Robusta coffee plants prefer well-drained soils and can grow in a variety of soil types, including sandy and loamy soils. Yet, they do not thrive in clay soils.

Robusta coffee plants are hardier than Arabica coffee plants and require less maintenance. They are also more resistant to pests and diseases.

Harvesting Techniques

Robusta coffee beans are usually harvested by hand. The harvesting season varies depending on the region but typically occurs between October and February. During this time, the coffee cherries are at their peak ripeness and are ready to be picked.

Two main harvesting techniques are used for Robusta coffee beans: strip picking and selective picking. Strip picking involves removing all the cherries from a branch at once, regardless of their ripeness. This method is faster but can result in lower-quality beans.

Selective picking involves picking only the ripe cherries by hand. This method is slower but results in higher-quality beans. It requires multiple passes through the coffee plantation as the cherries ripen at different times.

After harvesting, the coffee cherries are processed to remove the outer layers and reveal the coffee beans inside. The processing method can affect the flavor and quality of the coffee beans.

Processing and Roasting

Once the Robusta coffee beans are harvested, they need to be processed and roasted to bring out their unique flavor profile. The processing and roasting methods used for Robusta beans differ slightly from those used for Arabica beans.


The processing of Robusta coffee beans involves separating the beans from the hulls and parchment and then drying them. There are two primary methods of processing Robusta beans – the dry method and the wet method.

The dry method involves leaving the beans out in the sun to dry naturally. This method is typically used in areas with low humidity, with little chance of rain.

On the other hand, the wet method involves washing the beans to remove the hulls and parchment before drying them. This method is used in locations with high humidity, where the beans will spoil if left out in the sun.


Roasting is where the magic happens. Applying heat to green coffee beans to transform them into the roasted coffee beans that we all know and love. The roasting process is crucial to the flavor profile of the coffee, and each roast levels brings out different flavors and aromas.

Robusta coffee beans are typically roasted darker than Arabica beans to bring out their bold and strong flavor profile.

The beans are heated to a specific temperature during the roasting process and then cooled rapidly to prevent over-roasting. The beans are then packaged and shipped to coffee shops and stores around the world.

Environmental Impact

Variations in precipitation and temperature can cause a decline in both the quantity and quality of harvest. This has a profound impact on the livelihoods of coffee growers who depend on robusta beans as their main source of income.

The effects of climate change on coffee production are already being felt in many parts of the world. Rising temperatures, unpredictable rainfall, and droughts are all factors that can negatively impact coffee crops. In addition, climate change can also lead to an increase in pests and diseases that can further damage coffee plants.

To mitigate the effects of climate change on coffee production, farmers are adopting sustainable farming practices that promote biodiversity, soil health, and water conservation. For example, using shade-grown coffee can help regulate temperature and moisture levels while providing a habitat for birds and other wildlife.

Coffee companies also starting to play a role in reducing the environmental impact of coffee production. Many companies are working to reduce their carbon footprint by implementing sustainable sourcing practices and investing in renewable energy.
