This article will explore everything you need to know about Robusta coffee, from its origin and taste to its benefits and market trends.

What is Robusta Coffee?

Robusta coffee, also known scientifically as Coffea canephora, is a species of coffee known for its intense flavor, higher caffeine content, and resistance to pests and diseases.

Robus­ta plants typ­i­cal­ly have a greater crop yield, con­tain high­er lev­els of caf­feine, low­er lev­els of sug­ar, high­er lev­els of sol­u­ble solids, and are less sus­cep­ti­ble to dam­ag­ing pests and dis­eases. Robusta beans are often used in espresso blends and instant coffee due to their bold taste and ability to hold the processing methods.

So, where are Robusta coffee beans cultivated? The top glob­al pro­duc­ers of robus­ta are cur­rent­ly Viet­nam, Brazil, Indone­sia, Ugan­da, and India, which togeth­er pro­duce over 90% of the world’s robus­ta.

Vietnam has positioned itself as one of the world’s leading coffee producers and exporters, second place behind Brazil. The country produced approximately 26.3 million 60-kilogram bags of Robusta coffee during the 2022/23 production period.

Brazil accounts for nearly half of the world’s coffee output, producing 16.8 million bags of coffee in 2023. Coffee is produced in 14 regions in Brazil, in the central coffee-growing cluster of states.

According to World Coffee Research, Uganda is known primarily for robusta production, with over 1.8 million households growing coffee, and coffee contributes nearly a third of the country’s export earnings.

Indone­sia is another leading coffee producer, exporting most of its coffee beans. The country produced ten million 60kg bags of Robusta coffee in 2022 and 2023. Indonesia’s coffee market revenue is expected to reach US$4 billion by 2028.

India’s coffee legacy traces back to ancient times as far as the 16th century. Robusta production in India amounted to 4,420 thousand 60 kilogram bags in 2022/2023.

Approximately 90% of the Robusta coffee grown in these regions is produced for export to other countries such as Germany, Italy, and the United States for commercial coffee blends.

Characteristics of Robusta Coffee

Robusta coffee, scientifically known as Coffea canephora, is a coffee variety celebrated for its unique characteristics. Robusta stands apart in the coffee industry from its flavor to where it thrives.

Flavor Profile

Robusta coffee is renowned for its bold and robust flavor. It carries a deep, earthy taste, often accompanied by nutty or woody undertones. Robusta’s taste profile is more straightforward than its counterpart, Arabica, which boasts a broad range of flavors. It tends to be noticeably bitter, making it a popular choice for those who enjoy a stronger and more intense coffee experience.

Aroma

The aroma of Robusta coffee is distinctively different from Arabica. It tends to have a somewhat astringent aroma, which is less fragrant and floral than Arabica’s delicate scents. Robusta’s aroma is often described as earthy or woody, reflecting its hearty flavor.

Caffeine Content

One of the key characteristics that sets Robusta coffee apart is its high caffeine content. Robusta beans typically contain around 2.2-2.7% caffeine by weight, significantly more than Arabica’s 1.2-1.5%. This elevated caffeine level contributes to the coffee’s bitterness and boldness. It also makes Robusta beans more robust against pests and diseases, as caffeine acts as a natural pesticide.

Arabica vs. Robusta: What’s the Difference?

Arabica and Robusta take the top places in the coffee industry worldwide and appeal to very different palates.

Arabica is a species of coffee (Coffea arabica) known for its mild flavor, aromatic qualities, and acidity. It’s the most popular type of coffee, known for its complex flavors and smoothness. Robusta is characterized by its strong, sometimes harsh flavor and higher caffeine content.

Arabica is often considered more popular and synonymous with excellent quality; however, Robusta coffee has unique characteristics that make it stand out.

1. Flavor Profile

Arabica high-quality beans taste slightly sweet with floral notes and fruity, berry aromas. They tend to have a higher acidity than Robusta beans, which gives them a winey tone. When swallowed, there will be a bitter taste called the aftertaste of coffee.

Robusta coffee has a more pungent taste with earthy or woody undertones and a bitter flavor. The intensity of these taste and aroma characteristics is primarily determined by the degree of roasting.

2. Caffeine Content

According to the research study, Arabica beans have around 1.2-1.5% caffeine content per bean. The lower caffeine content contributes to Arabica’s milder flavor profile and is often preferred by those sensitive to caffeine or who prefer a smoother coffee experience.

Robusta coffee generally contains higher caffeine levels, typically having about 2.2-2.7% caffeine content. The caffeine content of the Arabica bean is roughly half that of the Robusta bean. The higher caffeine concentration lends Robusta its characteristic bold flavor and more robust taste.

3. Growing Conditions

Arabica coffee plants prefer tropical climates close to the equator. They can be cultivated in higher altitudes with cooler temperatures and ample rainfall. It’s cultivated in regions with altitudes ranging from 600 to 2000 meters.

Robusta coffee, on the other hand, is grown at lower altitudes, typically between 200 to 800 meters, in warmer climates with consistent temperatures and less precipitation. Robusta tends to be a hardier, more disease-resistant bean than Arabica, which is less expensive to maintain and produces a higher yield.

4. Bean Appearance

Arabica beans are typically more giant and have a more elongated shape than Robusta beans, which are smaller and more rounded. They have a smoother surface with a noticeable crease, or cleft, running along one side of the bean. Arabica beans often exhibit a range of colors, from light green when unripe to dark red or brown when fully mature.

On the other hand, Robusta beans are smaller and more rounded and can appear more irregular with a rougher texture. Robusta beans have a rougher texture, with a thicker outer layer, sometimes giving them a more rugged appearance. They typically have a straighter crease or no crease compared to Arabica beans. Robusta beans also tend to have a darker coloration, ranging from light brown to almost black, depending on the degree of roasting.

5. Price and Market Demand

Arabica coffee generally has a higher price in the market due to its superior flavor profile and perceived quality. It’s in higher demand among specialty coffee enthusiasts and takes a significant share in the global coffee market.

Robusta Coffee Beans Processing Methods

Processing Robusta coffee beans is a crucial step in determining the flavor and quality of the final product. Two primary methods are used to process these beans: dry processing and wet processing. Each method significantly impacts the taste and overall quality of Robusta coffee.

Dry vs. Wet Processing

Dry processing is the traditional method for Robusta coffee. In this process, the coffee cherries are spread out in the sun to dry. This method is more straightforward and less expensive, making it popular in regions with limited access to water.

As the cherries dry, the outer fruit layer shrivels and hardens, which is removed to reveal the coffee beans inside. Dry processing often produces a coffee with a heavier body and earthy, fruity flavors.

Conversely, wet processing involves removing the fruit layer from the coffee beans before drying. This method requires more water and equipment, making it more complex and costly.

In wet processing, the cherries are pulped to remove the outer layer, and the beans are fermented to break down any remaining mucilage.

After fermentation, the beans are washed and then dried. Wet processing produces a cleaner, brighter flavor with more acidity, so it is often used for higher-quality beans.

Impact on Flavor

The choice of processing method directly impacts the flavor profile of Robusta coffee. Dry-processed Robusta beans typically have a stronger, more robust flavor with notes of chocolate and nuts and a heavier body.

This method enhances the natural characteristics of Robusta coffee, making it bolder and more intense.

Wet-processed Robusta coffee tends to have a cleaner, smoother taste with more pronounced acidity. This method can highlight subtle flavors and improve the overall balance of the coffee. However, Robusta beans are less common because of the higher costs and resources involved.

Ultimately, the processing method chosen depends on the desired flavor profile and the resources available to the coffee producers. Both methods contribute to the rich diversity of flavors in Robusta coffee, allowing it to cater to a wide range of preferences among coffee enthusiasts.
