The robusta plant’s hardiness and high crop yield make Robusta an economical coffee bean choice. Robusta is often used for espresso blends and instant coffee. The bold flavor profile stands up well in drinks with milk like cappuccinos and lattes.

So while Arabica beans are more prized, Robusta coffee offers unique advantages. Robusta’s heartiness, higher caffeine levels and bold flavor expand options for coffee drinkers seeking cost-effective beans tailored to certain coffee types.

The History of Robusta Coffee beans Origin

Robusta coffee originates from the Coffea canephora plant first discovered in Central and West Africa in the late 19th century. The Robusta variety gets its name from being hardier and more disease-resistant than the Arabica coffee plant.

After Robusta’s initial discovery in the Congo region, colonial Robusta plantations expanded in Africa in the early 20th century. But World War II halted production growth. After African independence post-WWII, countries like Cameroon and Ivory Coast resumed Robusta cultivation with government support and smallholder farms.

Beyond Africa, Robusta was also grown in Brazil and Asian countries including Indonesia, India, the Philippines and Vietnam starting in the 1900s. Today, Vietnam is the second largest global coffee producer thanks to Robusta.

Initially less popular than the Arabica variety, Robusta usage increased over the 20th century due to its high productivity and low cost. Now Robusta accounts for around 40% of worldwide coffee production, establishing it as the second most popular coffee bean globally after Arabica.

Factors Influencing Robusta Flavor

Factors Influencing Robusta Flavor

As an experienced coffee expert, I can tell you that the flavor of robusta coffee is determined by four main factors:

  1. Plant strain: Different strains of robusta beans have varying levels of acidity and body, which greatly influence the overall flavor profile.
  2. Altitude: The altitude at which the beans are grown also plays a significant role in their flavor. Beans grown at higher altitudes tend to be more acidic, while those grown at lower altitudes have a smoother flavor.
  3. Shade trees: The presence of shade trees in the coffee plantation provides additional protection for the beans from direct sunlight. This protection helps to reduce bitterness and maintain a more consistent flavor profile.
  4. Processing method: The processing method used for robusta beans is crucial in creating a delicious cup of coffee. It affects both the aroma and body of the final product, contributing to its overall flavor experience.

These four factors work together to shape the unique flavor characteristics of robusta coffee.

Plant Strain

Robusta coffee beans come from a specific strain of plant, the Coffea canephora. This type of coffee is known for its hearty flavor and strong aroma, making it popular among those who appreciate a bold cup of joe.

The robusta strain is distinct from other types of coffee plants, primarily due to its genetic diversity, high caffeine content, thick husk covering the beans, natural resistance to pests and disease, and higher yield than arabica beans.

It’s these qualities that make robusta an ideal choice for anyone looking to enjoy a strong cup of coffee with excellent flavor.


Moving on from the plant strain of robusta coffee beans, let’s now discuss the altitude at which they are grown.

Robusta beans are often grown in humid and low-altitude regions like Vietnam, where sea level is approximately 0 meters. The civet coffee produced here is world-renowned for its flavor complexity.

On the other hand, Arabica beans require higher altitudes, usually between 900 and 1,500 meters for optimal growth. This means that Italian espresso blends will typically feature predominantly Arabica beans since they grow best in this region.

Despite their unique flavor profiles, however, some specialty shops still make use of Arabica-Robusta blends to create a unique taste experience.

Shade Trees

Shading the beans is an essential part of growing coffee, and robusta coffee can benefit from the shade of trees like avocados, guavas, and oranges. This helps to protect the delicate coffee cherries and preserves their flavor profile. Keeping the beans in a cool environment preserves their acidity, which makes them ideal for producing a great cup of instant coffee.

Moreover, shade-grown robusta varieties grown in Vietnam often have rich flavors that aren’t found with full sun-grown coffees.

Some of the benefits of using shade trees when growing robusta include:

  • Improved flavor: Shade trees help to preserve the flavor profiles in robusta beans, making them more desirable for use in specialty or instant coffees.
  • Increased crop yields: Coffee plants shaded by trees produce more cherries than those grown without shade, resulting in higher yields.
  • Higher quality product: With increased yields comes better quality control over the final product, ensuring only high-grade beans are used for brewing delicious cups of coffee.


After the beans have been harvested, they must be processed in order to prepare them for consumption.

Robusta coffee beans are usually processed using a traditional method called dry processing, which is more commonly used in Brazil. During this process, the ripe cherries are carefully placed on drying patios or raised beds and turned frequently until fully dried.

This process results in a cup that has a heavier body and stronger taste than other varieties of coffee. It also allows for a more traditional flavor expression than hybrid varieties like Coffea Canephora.

Dry processing helps bring out the full potential of Robusta’s unique flavor profile and intensifies its signature taste.

Robusta Coffee Extract

Robusta coffee extract comes from the Coffea canephora species of coffee beans. With its intense, earthy flavor and higher caffeine content, robusta extract adds complexity to recipes.

The extract contains almost twice the caffeine versus Arabica extract. It also provides powerful antioxidants that can benefit health. Studies show robusta extract’s antioxidant capacity is up to 30% higher than Arabica.

Popular uses for robusta extract include adding it to smoothies, baked goods, sauces, and coffee drinks. The bold, rich flavor pairs well with chocolate, nutty and caramel flavors. For example, some coffee shops add 2-5% robusta extract to espresso blends.

Robusta extract can be substituted 1:1 for instant coffee powder in recipes. The extract dissolves easily and does not alter texture. So it integrates seamlessly into diverse foods and beverages, enhancing both flavor and nutrition.

Robusta vs Arabica Coffee

Robusta vs Arabica Coffee

Robusta and Arabica are the two main coffee bean varieties, which differ significantly in taste, caffeine content, climate needs and origin.

Robusta beans naturally contain almost double the caffeine compared to Arabica – 2.2-2.7% vs 1.2-1.5% respectively. They also have a stronger, more bitter flavor profile. Meanwhile, Arabica has a sweeter, more complex taste.

Robusta thrives in warmer equatorial climates and lower altitudes of 0-700 meters above sea level. In contrast, Arabica requires cooler temperatures and higher altitudes around 600-2000 meters.

Historically, Robusta originated in central Africa’s Congo region. Arabica was first cultivated in the highlands of Ethiopia.

Finally, Robusta beans are typically 40-60% cheaper than Arabica. Robusta plants are hardier, higher yielding and less prone to disease. This results in lower production costs.

In summary, key differences like caffeine content, flavor, climate needs and disease resistance distinguish the two main coffee varieties. But both continue to have widespread appeal worldwide.


Robusta coffee beans have a strong, bold flavor that’s sure to satisfy even the most discerning coffee lover. Their intense taste profile is created by two main varieties: Coffea canephora var. Robusta and Coffea arabica var. Robusta.

The former is known for its earthy and chocolaty notes, while the latter has a more acidic aftertaste with hints of fruit or nuttiness. Italian-style blends usually feature a combination of both types to create unique flavor profiles that are perfect for espresso drinks.

Growing Environment

Moving from the taste of robusta coffee beans to their growing environment, I can say that these beans require a specific climate in order to thrive.

Robusta grows best in hot, humid climates like those found in Southeast Asia and Africa. It prefers temperatures between 21-24 degrees Celsius (70-75 Fahrenheit) and an annual rainfall of 150 cm or more (59 inches).

The soil should be well-drained and slightly acidic, with a pH range between 4.5 – 6.5. Without this ideal environment, the beans won’t be able to produce optimal flavor or yield potential.


You’ll be delighted to learn that robusta beans have a fascinating origin story. Originating in Ethiopia, these dark-roasted beans spread throughout the world via traders and merchants, becoming popular for their higher caffeine content and intense flavor.

Here’s more on their origins:

  • First cultivated in the highlands of Ethiopia
  • Popularized by Italian coffee traders in the 19th century
  • Widely grown throughout Africa, India, Indonesia, and Vietnam
  • Now used in many espresso blends due to its strong flavor profile

Caffeine Content

Looking to get an extra boost? Robusta beans are known for their high caffeine content. In fact, it contains around twice the amount of caffeine found in Arabica beans.

BeansCaffeine Content
Robusta2.7 – 4%
Arabica1.5 – 1.7%

There is some variability depending on the variety and roast level of the coffee beans, but typically Robusta has a higher concentration of caffeine than Arabica. This makes it perfect for providing you with that extra jolt to help power through your day or late night studying session!


When it comes to cost, Robusta beans are typically more affordable than Arabica beans. They’re about 25% cheaper than their Arabica counterparts. This makes them a popular choice for those looking for an economical alternative.

The price also depends on the country of origin and the quality of the bean. For example, high-end Robusta beans from Vietnam can be quite expensive compared to standard grade Arabica beans from Brazil.


Higher altitudes mean more complex flavors, so the altitude of the beans affects their flavor profile. Robusta coffee beans are typically grown from sea level up to around 1,500 meters (4,921 feet) above sea level.

Sea LevelLight & Sweet
1,200mRobust & Complex
1,500mBold & Intense

At lower altitudes, these robusta beans have a light and sweet flavor profile. As altitude increases to 900 meters (2,953 feet), the flavor becomes balanced with both sweet and bold tastes. At 1,200 meters (3,937 feet) robusta beans offer a more robust and complex taste.

Finally at an altitude of 1,500 meters (4,921 feet), they have a bold and intense flavor that is much different than those grown near sea level. Knowing this information can help you pick out higher quality robusta coffee beans for your favorite roasts or blends.

Beans Size

Having discussed the altitude at which robusta coffee beans are grown, let’s take a closer look at the size of the beans.

Generally speaking, robusta beans are larger and heavier than other types of coffee bean. They tend to be oval-shaped with flat sides and a blunt tip on one end. The color can range from greenish-brown to dark brown depending on the roast level.

When it comes to taste, robusta has an earthy flavor that is slightly bitter and has notes of nuts or cocoa. It is also characterized by its strong aroma and full body.

Frequently Asked Questions
