History

The origins of robusta coffee can be traced back to the early 20th century, when it was first discovered in the highlands of present-day Uganda. At the time, the coffee plant was known locally as “kawa kudde,” which means “coffee of the Kudde tribe.”

The plant was later renamed “robusta” by the Italian botanist Luigi Zuccagni-Orlandini, who was responsible for introducing the plant to Europe in the 1890s. He chose the name “robusta” due to the plant’s hardy nature and resistance to diseases and pests, which made it easier to cultivate than other types of coffee.

Definition of Robusta Coffee

Robusta coffee refers to coffee beans that are derived from the Coffea canephora plant, which is a species of coffee plant native to West and Central Africa. The beans are characterized by their strong, full-bodied flavor and high caffeine content.

Characteristics of Robusta Coffee

Robusta coffee is known for its resistance to diseases and pests, as well as its high yield. It is typically grown in warmer, more humid climates at lower altitudes than Arabica coffee, which is another popular type of coffee plant.

Robusta coffee plants have a more upright growth habit than Arabica plants, and they produce more fruit per plant. The fruit of the robusta plant is oval-shaped and contains two seeds, which are the coffee beans. The beans are smaller and more oval in shape than Arabica beans, and they have a harder, denser texture.

Taste of Robusta Coffee

Robusta coffee (Coffea canephora) is known for its robust flavor, which is often described as having a nutty or earthy taste. This flavor is largely due to the higher levels of chlorogenic acid and other compounds found in Robusta coffee beans. Chlorogenic acid is a type of polyphenol that is present in many plant-based foods and is known for its antioxidant properties.

However, Robusta coffee is also known for its harsh, bitter flavor, which is due in part to its high caffeine content. While Arabica coffee typically contains about 1-1.5% caffeine, Robusta coffee can have up to 2.7% caffeine. This higher caffeine content gives Robusta coffee a stronger, more bitter flavor, and can also make it more stimulating for those who drink it.

Factors that Affect the Taste of Robusta Coffee

There are several factors that can affect the taste of Robusta coffee, including the growing and harvesting conditions, the roasting process, and the brewing method.

Growing and harvesting conditions

The taste of Robusta coffee can be influenced by the conditions in which the coffee plants are grown and the beans are harvested. For example, the soil, altitude, and climate in which the coffee plants are grown can all impact the flavor of the beans. Coffee plants that are grown at higher altitudes, for instance, may produce beans with a sweeter, less bitter flavor due to the cooler temperatures and stable climate.

The harvesting process can also affect the taste of Robusta coffee. Coffee beans are typically harvested either by hand or by machine, and the method used can impact the quality and flavor of the beans. Hand-harvested beans are generally considered to be of higher quality due to the more careful and selective picking process, while machine-harvested beans may be more prone to damage and defects.

Roasting process

The roasting process can also have a significant impact on the taste of Robusta coffee. During the roasting process, the beans are subjected to high temperatures, which causes a number of chemical reactions to take place. These reactions can alter the flavor and aroma of the beans, and can also reduce the acidity and bitterness of the coffee.

The roast level, or degree of roasting, can also affect the taste of Robusta coffee. Light roast coffee tends to have a brighter, more acidic flavor, while medium roast coffee has a more balanced, smoother flavor. Dark roast coffee, on the other hand, has a more intense, bold flavor due to the longer roasting time and higher temperatures used in the process.

Brewing method

The brewing method can also impact the taste of Robusta coffee. Different brewing methods, such as drip brewing, French press, or espresso, can extract different flavors and aromas from the beans, resulting in a wide range of flavors and strengths.

For example, drip brewing tends to produce a milder, more balanced flavor, while French press brewing results in a richer, fuller-bodied flavor. Espresso, on the other hand, is known for its strong, concentrated flavor and crema, or layer of foam, on top of the coffee.

Blending with Arabica Coffee

One way to soften the harsh, bitter flavor of Robusta coffee is to blend it with Arabica coffee, which is known for its sweeter, smoother flavor. Many commercial coffee blends contain both Robusta and Arabica beans in varying proportions, depending on the desired flavor profile and price point.

Blending Robusta and Arabica coffee can also result in a more

balanced flavor and aroma, as the flavors of the two types of beans can complement each other. For example, the nutty, earthy flavors of Robusta coffee can be paired with the sweeter, fruitier flavors of Arabica coffee to create a more complex and nuanced flavor profile.

Additionally, blending Robusta and Arabica coffee can also help to reduce the acidity and bitterness of the final product, making it more palatable for some drinkers.

Overall, the taste of Robusta coffee is largely determined by the growing and harvesting conditions, the roasting process, and the brewing method. While it is known for its robust, nutty or earthy flavor, it can also have a harsh, bitter taste due to its high caffeine content. Blending Robusta coffee with Arabica coffee can help to soften the harsh flavors and create a more balanced, complex flavor profile.

Production of Robusta

Today, robusta coffee is grown in many countries around the world, including Brazil, Vietnam, Indonesia, India, and West and Central Africa. The plant is typically grown at lower altitudes than other types of coffee, and requires a warmer, more humid climate to thrive.

Robusta coffee is typically harvested by hand, and the beans are processed using one of two methods: the dry process, in which the beans are left to dry in the sun, or the wet process, in which the beans are fermented to remove the outer layers before being dried.

Future of Robusta

Despite the challenges facing robusta coffee, it is likely to continue to be an important crop for many farmers around the world. Its hardy nature and high yield make it an attractive choice for farmers, and its strong, full-bodied flavor makes it popular among consumers.

In the future, it will be important for the coffee industry to continue to work towards sustainable production methods and address the challenges facing robusta coffee, in order to ensure the long-term viability of the crop.

Despite its popularity, robusta coffee faces a number of challenges in the future. The plant is sensitive to changes in temperature and rainfall patterns, which can impact crop yields. It is also vulnerable to pests and diseases, which can reduce crop yields and increase production costs.

Climate Change

One major challenge facing robusta coffee is climate change. Higher temperatures and changing rainfall patterns can impact the growth and development of the plant, leading to reduced crop yields and lower quality beans.

In addition, rising sea levels and increasing frequency of extreme weather events, such as floods and droughts, can also negatively impact robusta production. These events can destroy crops, wash away topsoil, and disrupt supply chains, all of which can lead to lower production levels and higher prices for consumers.

Pests and Diseases

Another challenge facing robusta coffee is the threat of pests and diseases. The plant is vulnerable to a number of pests, including the coffee berry borer, which feeds on the berries and can reduce crop yields. The plant is also susceptible to fungal diseases, such as coffee rust, which can damage the leaves and reduce crop yields.

These pests and diseases can be controlled through the use of pesticides and other chemicals, but these chemicals can have negative impacts on the environment and human health. In addition, overuse of pesticides can lead to the development of resistant pests, which can further reduce crop yields.

Competition from Other Crops

Robusta coffee is also facing increasing competition from other crops, such as cocoa and oil palm. These crops are often more profitable for farmers due to higher demand and higher prices. This can lead to a shift away from coffee production, which can impact the supply of robusta coffee on the global market.

Sustainable Production

Despite these challenges, there are a number of efforts underway to promote sustainable production of robusta coffee. The Sustainable Agriculture Network (SAN) is a group of coffee-growing organizations that work to promote sustainable farming practices, including guidelines for water management, soil conservation, and the use of pesticides and chemicals.

In addition, many coffee companies are working to improve their supply chains and support sustainable production methods. For example, some companies are working with farmers to implement sustainable farming practices, such as using organic fertilizers and reducing water usage.
