What is Robusta Coffee?

Robusta coffee, scientifically known as Coffea canephora, is a species of coffee that is cherished for its strong, full-bodied taste and high caffeine content. Unlike Arabica, Robusta thrives in lower altitudes and warmer climates, making it a staple in regions across Africa, Indonesia, and Vietnam. It’s often characterized by its robust flavor, which can range from earthy to woody, and sometimes includes a slightly bitter or chocolatey edge.

Personal anecdotes from my travels to Vietnam reveal the unparalleled strength and character of Robusta coffee. Sitting in a tiny café in Hanoi, sipping on a traditional Vietnamese coffee made from Robusta beans, the robust flavor and potent kick were unlike any coffee experience I had encountered in the West. This encounter was a revelation, highlighting Robusta’s powerful presence and its pivotal role in cultures around the globe.

The different types of Robusta coffee

Types of Robusta Coffee Characteristics
Ateng Ateng is a common name for Catimor coffees widely planted in Sumatra and other Indonesian isles. It is a subtype of Robusta coffee that offers intense flavors and robust qualities.
Robusta Varieties Robusta coffee, also referred to as Coffea Robusta, accounts for roughly 25% of the world's commercial coffee production. It is known for its increased levels of bitterness, higher caffeine content, and lower perceived sweetness compared to Arabica coffee. Robusta comes in various forms and varieties, each contributing to its unique taste profile.
Cross-Bred Varieties Robusta coffee has cross-bred varieties that are often hard to identify but are recognized for their intense and woody flavor notes. These varieties are cultivated in countries like Uganda, known for producing high-quality Robusta coffee beans with superior cup quality and distinct flavors.
Guinean and Congolese Groups Within the genetic makeup of Coffea canephora (Robusta), there are two broad genetic groups – Guinean and Congolese. The Guinean group originated in central-west Africa, while the Congolese group originated in central Africa. These genetic groups further divide into subgroups like "kouilou" or "conilon" within the Guinean group.
Subcategories Recent studies using advanced genetics techniques have further refined the Robusta species into eight subcategories based on genetic relationships within Coffea canephora. These subcategories help classify the different genetic variations present within the Robusta coffee plant.

Robusta Coffee vs Arabica Coffee

When comparing Robusta to Arabica, the differences are stark. Arabica beans are celebrated for their smooth, nuanced flavors and lower caffeine content. They require cooler climates and higher elevations to flourish, which contributes to their higher cost of productionand, consequently, retail price. Robusta, on the other hand, is seen as the more accessible, hardier option. Its beans pack a punch in terms of flavor and caffeine, offering a stark contrast to the gentle sophistication of Arabica.

A comparative analysis of the two species reveals that Robusta beans contain almost double the amount of caffeine found in Arabica beans. This not only makes Robusta coffee stronger but also provides natural resistance against pests and diseases, reducing the need for chemical pesticides.

Robusta Coffee Beans

Robusta coffee beans are often noted for their distinctive shape and size, which is slightly rounder and smaller than that of Arabica beans. This physical difference is a minor indicator of the vast differences in taste and chemical composition between the two species. When it comes to processing, Robusta beans are generally more forgiving, capable of enduring harsher conditions without significant loss in quality. This resilience translates into a more stable supply chain and, often, lower prices for consumers.

Robusta Coffee Taste

The taste of Robusta coffee is frequently described as bold and intense, with a natural earthiness that can be an acquired preference. Unlike the subtle floral and fruity notes of Arabica, Robusta’s flavor profile leans towards dark chocolate, burnt wood, and sometimes a hint of tobacco. Critics often label it as harsh, yet for enthusiasts, this robust profile is exactly what sets it apart, offering a deeper, more immersive coffee experience.

Robusta Coffee Caffeine Content

One of the most significant advantages of Robusta coffee is its high caffeine content. On average, Robusta beans contain about 2.7% caffeine by weight, compared to 1.5% in Arabica beans. This not only contributes to its strong taste but also offers a more considerable energy boost. For those who rely on their morning cup to kickstart their day, Robusta delivers an unmatched vigor.

Robusta Coffee Brands

Several brands have recognized the unique appeal of Robusta coffee and have begun to market it more aggressively. From traditional Vietnamese brands like Trung Nguyen to Western brands venturing into more robust blends, the options for exploring Robusta coffee are expanding. These brands often highlight the bean’s strength, durability, and affordability, catering to a niche yet growing segment of coffee enthusiasts.

Best ways to prepare robusta coffee

Brewing Robusta Coffee

Use a finer grind size for robusta coffee, as it is better suited for espresso machines or brewing methods that require a finer ground size. 

Robusta beans need more heat during extraction compared to Arabica to bring out the sweet, smoky notes without bitterness. 

For espresso brewing, use a 20g+ coffee dose with a brewing temperature between 194-196°F (90-92°C). Aim for a 1:2 brewing ratio and a 23-second extraction time.

For pour-over, start with 15g of finely ground robusta, pre-wet the grounds with 30ml of hot water, and pour the remaining 170g of water for a total brew time of 1:30-1:45 minutes. 

When brewing robusta, make subtle adjustments to grind size, brew time, and water temperature to explore the variety of flavor profiles.

THE SECRET TO BREWING ROBUSTA: It’s the water

Robusta Coffee Pairings

Robusta coffee pairs well with milk or plant-based milk alternatives, as the fatty and sweet nature can temper the bitterness.

Try making Vietnamese Cà Phê Sữa Đá, balancing Robusta’s boldness with the smoothness of condensed milk. 

Create a robusta affogato by pouring a hot espresso shot over vanilla ice cream, balancing the intense robusta with the sweet and cool creaminess.

Experiment with spiced robusta or cold brew robusta to further enhance the flavor profile.

The key to preparing great robusta coffee is using the right grind size, brewing temperature, and techniques to extract the best flavors, while also considering complementary pairings like milk or desserts.

Robusta Coffee Side Effects

1. Bitter Taste

For some, the robust and sometimes bitter flavor of Robusta coffee is an acquired taste. This characteristic, while appealing to many, can be off-putting for those accustomed to the milder, more aromatic profile of Arabica.

2. Lower Quality

The reputation of Robusta coffee has been marred by associations with lower quality, especially when compared to the high standards often attributed to Arabica beans. This perception is slowly changing, though, as specialty Robusta producers focus on quality and sustainability.

3. Higher Caffeine Content

While the high caffeine content of Robusta is often seen as a benefit, it can also be a drawback for those sensitive to caffeine’s effects. Overconsumption can lead to jitteriness, anxiety, and difficulty sleeping for some individuals.

Robusta Coffee Uses

1. Espresso Blends

Robusta beans are a popular choice for espresso blends due to their strong flavor and rich crema. The high caffeine content and bold taste of Robusta complement the intensity of espresso, making it a favorite among coffee aficionados.

2. Instant Coffee

The robustness and lower cost of Robusta beans make them an ideal choice for instant coffee production. Their strong flavor survives the processing better than the subtler notes of Arabica, resulting in a more flavorful instant coffee.

3. Dark Roasts

Robusta beans hold up well to dark roasting, retaining their strong, bold flavors even when subjected to high temperatures. This makes them a preferred choice for those who enjoy a darker, more intense coffee.

4. Vietnamese Coffee

In Vietnam, Robusta coffee is the backbone of the national coffee culture. Traditional Vietnamese coffee, known for its strong flavor and thick texture, is primarily made using Robusta beans, often condensed with sweetened condensed milk to balance its intensity.
