Brewing Up a Better Cup: Exploring the Difference Between Arabica and Robusta Coffee Beans

Arabica and Robusta coffee beans are the two main types of coffee beans used for making espresso drinks. Arabica beans are from a species of coffee shrubs native to the mountains of Ethiopia, called Coffea Arabica, while Robusta beans come from a species of shrub native to southeast Asia, called Coffea Canephora. The primary distinction between the two is their flavor profile, with Arabica having a much more complex and nuanced flavor than Robusta. Arabica coffee is thought to be superior in quality, as it has more natural sweetness, less bitterness, and less caffeine than its Robusta counterpart. Robusta, on the other hand, is known for its strong flavor and high caffeine content, making it an ideal choice for espresso drinks. In addition to flavor, Arabica coffee beans also tend to be more expensive than Robusta due to their higher quality.

Overview of Coffee

Coffee beans are the seeds of the coffee plant (Coffea sp.), and the two main species used to produce coffee are Arabica (C. arabica) and Robusta (C. canephora).

Arabica coffee beans are typically more expensive than Robusta beans because they are generally considered to have a better flavor. Arabica beans are narrow and oblong in shape, with less caffeine and acidity than Robusta beans. These beans tend to have a nutty flavor and a sweet, fruity aroma.

Robusta coffee beans are larger and rounder than Arabica beans, and contain more caffeine and a higher level of natural sugars. This gives them a strong, bitter taste and a distinctive aroma. These beans are usually used in espresso blends and widely available in instant coffees.

Overview of Robusta and Arabica Beans

The primary difference between Arabica and Robusta beans is their taste. Arabica beans have a sweeter, milder flavor, while Robusta beans tend to have an earthy, harsher flavor. Arabica beans are also higher in sugar and lower in caffeine than Robusta beans, making them preferred by coffee connoisseurs.

Arabica beans are grown in South and Central America, as well as India and parts of Africa. Robusta beans are grown mostly in Southeast Asia, as well as parts of Africa. Arabica beans are usually more expensive than Robusta beans, since they are more labor-intensive to grow and Arabica’s typically produce a higher-quality cup of coffee.

In terms of physical appearance, Arabica beans tend to be oblong and flatter. Robusta beans are rounder in shape and have more of a waxy texture on their surfaces. Arabica beans also average around 780-900 in Cuppings score, a measure of coffee quality, while Robusta beans average around 500-700.

Differences Between Arabica and Robusta

The primary difference between Arabica and Robusta coffee beans is the flavor. Arabica beans have a much sweeter, softer, more subtle flavor profile, while Robusta can be quite bitter and harsh. Arabica beans are also higher in sugar content, caffeine content, and acidity, providing a higher-quality, milder cup of coffee than Robusta.

In terms of farming, Robusta beans are generally grown at a much lower altitude than Arabica, making them less expensive to produce. Robusta beans also tend to be more resistant to diseases, so farmers don’t have to resort to chemical pesticides as often.

In terms of price, Robusta beans are usually much cheaper than Arabica beans. This is mainly due to the fact that Robusta is easier to farm and has a higher yield.

Finally, when it comes to roasting, Arabica beans tend to be more forgiving, allowing for subtle flavor profiles to shine through, whereas Robusta beans don’t have the same flexibility. This makes Robusta beans more difficult to roast correctly but produces a high-quality, bold flavor once it is done.

Growing and Harvesting

The main difference between Arabica and Robusta coffees lies in the way they are grown and harvested. Arabica coffee beans are generally grown at higher elevations, on the slopes of mountains, and in shaded areas. They are often handpicked, which allows the farmer to select only ripe and healthy beans. Robusta beans, on the other hand, are widely grown in lowland areas, where conditions are less hospitable. They can be grown in a variety of climates and they are usually harvested by machines, which tend to damage and over-ripen the beans.

Flavor Profile

The flavor profile of Arabica coffee beans is known for its subtle, sweet, and acidic undertones. It has a smooth body and mild flavor, with a fragrant aroma. These characteristics make it the preferred choice for many specialty coffee drinks.

Robusta coffee beans, on the other hand, have a strong, bitter flavor with a high level of caffeine. The body of the cup is thick and the bean contains more bitter components than an Arabica bean, resulting in a stronger taste. They are usually used in lower-cost blends, such as instant coffee or espresso.

Acidic Levels

In the context of Arabica and Robusta, acidity is used to refer to the levels of organic compounds and inorganic acids that exist in roasted and brewed coffee. Arabica beans tend to have a softer, sweeter character and lower acidity compared to Robusta beans, which have a harsher, more earthy taste and higher acidity. Generally, Arabica coffee is said to have a milder, lighter taste than Robusta coffee, which is strong and full-bodied.

Brewing With Robusta and Arabica

The two major types of coffee beans are Arabica and Robusta. Arabica coffee beans are more flavorful, have less caffeine, and are more expensive to produce. Robusta coffee beans contain more caffeine and are often used in espresso blends. They also have a more bitter taste, higher acidity, and stronger astringency than Arabica beans.

Brewing with a combination of the two types of beans has its benefits. It allows one to achieve a unique flavor profile that combines the complex taste of the Arabica beans with the robust flavor of the Robusta beans. Blending the beans together can result in a coffee with a strong flavor and body, but with a more nuanced and balanced taste than one made from a single type of bean. Additionally, the higher caffeine content of Robusta beans can provide an added energy boost.

Using Robusta or Arabica for Espresso

What’s the difference between Arabica and Robusta coffee beans?

The two main types of coffee beans are Arabica and Robusta. Arabica beans are generally considered to be of higher quality than Robusta beans, as they have a sweeter and more complex flavor. Arabica beans typically contain higher levels of caffeine and produce a more aromatic cup of coffee. Arabica beans are more expensive than Robusta beans and are used in most specialty coffee drinks like espresso. Robusta beans contain twice the amount of caffeine as Arabica beans and have a more bitter and robust flavor. Robusta beans have a more intense flavor profile and are often used to create a full-bodied espresso. Arabica beans may be considered the better choice for espresso as they create a richer flavor with less bitterness.

Mixing Robusta and Arabica Beans

Mixing Robusta and Arabica beans can be beneficial for coffee drinkers in a few ways. Robusta beans typically have a higher caffeine content than Arabica beans, and a stronger, more intense flavor. Arabica beans, on the other hand, tend to be milder in flavor and contain more aromatic oils and compounds, resulting in a sweeter taste. By combining the two beans, a barista can craft a truly unique cup of coffee with a flavor intensity and complexity not achievable via a single bean varieties. Still, it’s important to understand the various qualities of each type of bean in order to attain the desired outcome.

Typical Roasting Techniques

The primary difference between Arabica and Robusta coffee beans is in their flavor and aroma, stemming from differences in their roasting techniques. Arabica beans are typically roasted at a low to medium temperature for a longer period of time, resulting in a smoother, more complex flavor. Robusta beans, on the other hand, are typically roasted at a higher temperature for a shorter amount of time. This process helps to bring out the higher levels of caffeine that Robusta beans inherently contain, while also developing a more intense, robust flavor.


Arabica beans are generally known as the superior bean, with a sweeter taste, higher acidity, and more complex flavor compared to Robusta beans. Arabica beans tend to be more expensive than Robusta beans but are also more difficult to grow and harvest. Because of their complexity and expensive price, Arabica beans are typically used in specialty coffee drinks. By contrast, Robusta beans are higher in caffeine and have a more bitter taste and lower acidity. Because of their lower cost and higher caffeine content, Robusta beans are often used as an ingredient in lower-end, instant coffee mixes.

Summary of the Differences

Arabica beans are sweeter, smoother, and contain more natural sugars than Robusta beans. Arabica beans have a mild flavor, lower caffeine content, and contain less oil than Robusta beans. Arabica beans are considered to be the higher-quality option, and are generally more expensive than Robusta beans. The taste of Arabica beans is often described as sweet and floral, while Robusta beans can be more bitter. Arabica coffee beans also tend to have a higher acidity than Robusta beans.
