Arabica vs Robusta What the difference

Arabica vs Robusta: What's The Difference?

Do you ever wonder why coffee tastes so different depending on where it comes from? One of the main factors that affects the taste. There are two main types of coffee beans - Arabica and Robusta - and they each have their own distinct characteristics. So grab a cup of Coffee of Death and let's dive in!


Difference between Arabica and Robusta beans

Size: Arabica beans are larger and longer than Robusta beans. They have a slightly curved shape and a more oval appearance, while Robusta beans are rounder and smaller. 

On average, Arabica beans are about 1 cm long and 0.6 cm wide, while Robusta beans are around 0.8 cm long and 0.5 cm wide. The size and shape of the beans can vary depending on the variety and growing conditions, but as a general rule, Arabica beans are slightly larger and more oval in shape, while Robusta beans are more round and compact.

Growing conditions:  Arabica beans are typically grown at higher altitudes, in cool and subtropical climates. Temperatures ranging from 15°C to 24°C (59°F to 75°F). The ideal temperature for Arabica coffee cultivation is around 18°C to 21°C (64°F to 70°F), with moderate humidity and rainfall.

Robusta coffee is typically grown in hotter and more humid climates, with average temperatures ranging from 24°C to 30°C (75°F to 86°F). The ideal temperature for Robusta coffee cultivation is around 24°C to 26°C (75°F to 79°F), with plenty of rainfall and sunshine. Unlike Arabica coffee, Robusta coffee plants are more resistant to heat and humidity, and can tolerate a wider range of temperatures and weather conditions.

Taste: Arabica coffee is characterized by a diverse range of flavors and aromas, including subtle notes of fruit, berries, chocolate, and nuts, which contribute to its smooth and well-balanced taste profile.

On the other hand, Robusta coffee has a noticeably different taste profile, often described as more robust, bold, and with earthy and woody undertones, partly due to its higher caffeine content.
