Coffee is more than just a morning ritual for many people; it’s an integral part of daily life, culture, and productivity worldwide. As coffee enthusiasts delve into various types of coffee, the debate about caffeine content often arises, particularly between Robusta and Arabica coffee. In this article, we will explore the world of Robusta coffee, examining its caffeine content, characteristics, and the factors influencing its potency.
Understanding Coffee Types: Robusta vs. Arabica
Before jumping into caffeine content, let’s establish the two primary types of coffee beans: Robusta and Arabica.
Arabica Coffee Beans
Arabica coffee beans, scientifically known as Coffea arabica, account for approximately 60% to 70% of the world’s coffee production.
