A Brief Explanation of Table

1. Species:

Robusta coffee beans, scientifically known as Coffea canephora, originate from a plant that is known for its hardy nature and resistance to harsh growing conditions.

It is one of the main species of coffee beans and is widely cultivated, particularly in Africa and Southeast Asia.

Arabica coffee beans, scientifically known as Coffea arabica, come from a plant considered the premium species of coffee.

Arabica beans are known for their delicate flavor, and nuanced aroma, and are generally associated with higher-quality coffees.

They are the most widely grown species and are prevalent in regions like Latin America, Africa, and Asia.

2. Caffeine Content:

Robusta beans have a higher caffeine content, ranging from 2.2% to 2.7% of their composition. This higher caffeine concentration gives Robusta coffee a more intense, bitter taste compared to Arabica.

Arabica beans contain less caffeine, typically ranging from 1.2% to 1.5%. The lower caffeine content contributes to a smoother, less bitter taste in Arabica coffee.

3. Flavor Profile:

Robusta coffee is often characterized by a more robust and harsh flavor profile. It tends to have a grain-like overtone and a pronounced bitterness, making it an acquired taste for some.

Arabica coffee is celebrated for its smoother and more complex flavors. It offers a wide range of taste notes, including fruity, nutty, chocolaty, and floral, resulting in a more enjoyable and varied taste experience.

4. Shape:

Robusta beans are typically rounder and smaller in size compared to Arabica beans. They are characterized by a more circular shape.

Arabica beans have a more elongated shape and are generally larger compared to Robusta beans. They are known for their distinct, oval-like appearance.

5. Plant Size:

Robusta plants are larger, often reaching heights of 10-12 meters. Their larger size contributes to the production of more beans per plant.

Arabica plants are smaller in size, usually growing up to 6 meters in height. Their compact size makes them easier to manage and harvest.

6. Growing Altitude:

Robusta plants thrive at lower altitudes, typically 600 to 900 meters above sea level. They are well-suited to warm, lowland regions.

Arabica plants prefer higher altitudes, usually above 900 meters. They thrive in cooler, mountainous regions with specific climate conditions.

7. Climate Tolerance

Robusta is known for its resilience and ability to tolerate warmer climates. It can withstand higher temperatures and is less sensitive to its growing environment.

Arabica is more delicate and requires specific conditions, including cooler temperatures and consistent rainfall. It is more sensitive to its growing environment.

8. Disease Resistance:

Robusta beans have a higher natural resistance to pests and diseases, making them easier to cultivate and manage.

Arabica beans are more susceptible to pests and diseases, necessitating careful management and monitoring during cultivation.

9. Lipid and Sugar Content:

Robusta beans generally have lower lipids and sugar levels than Arabica beans, affecting their overall taste and aroma.

Arabica beans have higher lipid and sugar content, contributing to their sweeter, more flavorful profile.

10. Price:

Robusta beans are usually more affordable in the market due to their higher yield and easier cultivation.

Arabica beans are priced higher due to their perceived superior quality, specific growing conditions, and lower yield.

11. Acidity:

Robusta beans generally have lower acidity compared to Arabica beans. This contributes to their stronger, more bitter, and earthy flavor profile.

Arabica beans typically have a higher acidity, leading to a brighter, more complex taste often described as fruity, floral, or even wine-like. This acidity also contributes to the richness and aroma of Arabica coffee.

12. Body:

Robusta coffee is known for its full-bodied and heavier mouthfeel, often described as a bold texture on the palate.

Arabica coffee has a lighter and smoother body, offering a more delicate and pleasant sensation in the mouth.

13. Crema:

Robusta beans generally produce less crema in espresso due to their lower sugar content and higher caffeine concentration.

Arabica beans yield a richer crema in espresso, enhancing the overall presentation and texture of the coffee.

14. Oil Content:

Arabica beans typically have a higher oil content (15-17%) compared to Robusta beans (10-12%). This difference in oil content can contribute to the distinct taste and aroma profiles of each bean type.

15. Growing Area:

Robusta has grown more widely on a global scale, particularly in Africa, Southeast Asia, and Brazil.

Arabica is predominantly grown in Latin America, including countries like Colombia, Brazil, and Ethiopia.

16. Common Use:

Robusta beans are commonly used in instant coffee and as part of coffee blends for their stronger flavor and cost-effectiveness.

Arabica beans are favored for specialty and gourmet coffee due to their nuanced flavors and higher quality.

17. Usage in Blends

Espresso blends often contain a higher proportion of Robusta beans to enhance crema and provide a more robust flavor.

Espresso blends may contain a higher proportion of Arabica beans for a smoother, more aromatic espresso.

18. Chlorogenic Acid Levels:

Robusta beans have higher levels of chlorogenic acid, contributing to their distinct taste and potential health benefits.

Arabica beans contain lower levels of chlorogenic acid compared to Robusta beans.

19. Solubility:

Robusta beans have higher solubility, allowing them to dissolve more easily during brewing.

Arabica beans have slightly lower solubility compared to Robusta beans.

20. Taste Notes:

Robusta coffee often exhibits nutty and woody taste notes, complementing its bold flavor profile.

Arabica coffee offers a more diverse range of taste notes, including fruity, floral, and sugary flavors, contributing to its complexity.
