Difference between Robusta and Arabica Coffee

Coffee is one of the most widely consumed beverages in the world. The two most commonly cultivated species of coffee are Coffea arabica and Coffea canephora (also known as Coffea robusta). These two species differ in terms of their taste, aroma, caffeine content, and other factors. In this article, we will explore the main differences between robusta and arabica coffee.

Origin and cultivation:

Arabica coffee is believed to have originated in Ethiopia, and it is now grown in many regions around the world, including South and Central America, Africa, and Asia. Arabica coffee plants require higher altitude and cooler temperatures, and they are typically grown at elevations between 600 and 2000 meters above sea level. Arabica coffee is more challenging to grow and requires more care and attention, making it more expensive than robusta coffee.

Robusta coffee, on the other hand, is native to Central and Western Africa and is now widely grown in many parts of the world, including Africa, Indonesia, and Vietnam. Robusta coffee plants thrive in hotter and more humid climates and can be grown at lower elevations, typically below 600 meters above sea level. Robusta coffee is easier to grow and is more resistant to pests and diseases, making it less expensive than arabica coffee.

Flavor and aroma:

Arabica coffee is known for its delicate and nuanced flavors, which can range from floral and fruity to nutty and chocolaty. Arabica coffee also has a distinct aroma, which is often described as sweet and fragrant. Arabica coffee is lower in bitterness and acidity, which makes it more palatable for many coffee drinkers.

Robusta coffee, on the other hand, has a stronger and more bitter taste, with a woody or earthy flavor. Robusta coffee is also higher in acidity and has a slightly burnt taste, which some people find unappealing. However, robusta coffee has a thicker and creamier texture, which some people prefer.

Caffeine content:

Robusta coffee contains about twice as much caffeine as arabica coffee. The higher caffeine content in robusta coffee is due to its genetic makeup and its adaptation to hotter and more stressful environments. Robusta coffee has a caffeine content of around 2.7% compared to arabica coffee, which has a caffeine content of around 1.5%.

Nutritional value:

Both arabica and robusta coffee contain several essential nutrients, including magnesium, potassium, and niacin. However, robusta coffee has higher levels of antioxidants and chlorogenic acid, which have been shown to have several health benefits, including reducing the risk of heart disease and type 2 diabetes.


Arabica coffee is typically more expensive than robusta coffee, as it is more challenging to grow and requires more care and attention. Arabica coffee is also in higher demand, as it is more widely consumed and is considered to be of higher quality.

Use in blends:

Many coffee blends contain a combination of arabica and robusta coffee. Blending arabica and robusta coffee can create a more balanced and complex flavor profile. In general, a blend with a higher percentage of arabica coffee will have a smoother and more nuanced taste, while a blend with a higher percentage of robusta coffee will have a stronger and more bitter taste.

In conclusion, arabica and robusta coffee are two different species of coffee that differ in terms of their origin, cultivation, taste, aroma, caffeine content, nutritional value, price, and use in blends. While both types of coffee have their unique characteristics and benefits, the choice of which one to consume ultimately comes down to personal preference.
