When it comes to coffee, there are two main types of beans: Arabica and Robusta. The age-old rivalry between Arabica and Robusta beans continues to shape the preferences of discerning coffee enthusiasts. Arabica beans are the most popular type of coffee bean, accounting for about 60% of the world's coffee production. Robusta beans, on the other hand, are less common and only account for about 40% of the world's coffee production. However, both are the two kinds of coffee beans used in commercial coffee production with their own speciality. These two primary coffee species offer distinct flavour profiles, characteristics, and growing conditions. Let's dive into the differences between Arabica and Robusta coffee beans to help you navigate the rich landscape of coffee choices.

The Difference of Arabica and Robusta Beans

1. Appearance

One of the main differences between Arabica and Robusta beans is their appearance. Arabica beans are typically larger and ovular in shape, while Robusta beans are smaller and rounder in shape. Arabica beans also have a long, curved center cut, while Robusta beans have a shorter, straighter centre cut.

2. Taste

They often have notes of fruit, chocolate, and sugar. In short, The taste can range from sweet and sugary to tangy and even wine-like. Robusta beans, on the other hand, have a stronger, more bitter flavour. They often have notes of earth, rubber, and burnt wood. The flavor is straightforward and less intricate than Arabica.

3. Caffeine Content

Robusta beans have about twice as much caffeine as Arabica beans. This is because Robusta beans grow in lower altitudes, where they are more exposed to pests and diseases. Caffeine is a natural insecticide, so Robusta beans produce more caffeine as a defence mechanism. With almost double the caffeine of Arabica, it provides a robust and energising experience.

Arabica beans are grown in higher altitudes, where the climate is cooler and more humid. Generally between 2,000 to 6,000 feet. They are more susceptible to diseases and require careful cultivation. Robusta beans, on the other hand, are more tolerant of heat and humidity. They are hardier and can grow at lower altitudes (around 2,000 feet), in warmer climates. This is why Robusta beans are often grown in lower altitudes.

Arabica plants thrive at higher altitudes with cooler temperatures, generally between 2,000 to 6,000 feet. They are more susceptible to diseases and require careful cultivation.
