On the flip side, Robusta coffee beans can easily grow at lower altitudes in warmer climates, typically ranging within 24-30 degrees Celsius. They are less vulnerable to damage from insects and pests and can grow well in both tropical and subtropical conditions. 

4. Caffeine Level

Arabica coffee beans generally contain lower levels of caffeine compared to Robusta coffee beans. On average, Arabica beans have 1.2-1.5% caffeine content, which is half of Robusta beans. That means the Arabica beans need to be brewed twice to get the exact caffeine like Robusta.

5. Planting

Planting Arabica beans is considerably more complex and expensive compared to Robusta beans because they cannot be planted all at once. Besides, farmers need to hand-pick every single cherry at different times, which can result in a higher rate of wastage, or not in a better position of processing and consumption. 

Conversely, Robusta beans are much easier and more cost-effective to plant than Arabica beans. They can be harvested all at once using machinery or by pulling entire branches, and as a result, minimize the risk of waste and provide higher production for processing and consumption. 

6. Source of Beans

Arabica beans are mainly cultivated in Brazil, Guatemala, Costa Rica, Columbia, and Ethiopia. They grow in tropical climates with an average rainfall of 1500-2500 mm per year and they are cross-species between canephora and eugeniodes. 

Alternatively, Robusta beans are mainly produced in Vietnam, Indonesia, and Thailand. They can grow both in tropical and subtropical climates with an average rainfall of 2200-3000 mm each year. It comes from the plant Canephora.
