Coffea Arabica
Coffea arabica also known as the Arabian coffee, "coffee shrub of Arabia", "mountain coffee", or "arabica coffee", is a species of Coffea. It is believed to be the first species of coffee to be cultivated, and is the dominant cultivar, representing some 60% of global production. Coffee produced from the (less acidic, more bitter, and more highly caffeinated) robusta bean (C. canephora) makes up most of the remaining coffee production.

About Robusta Coffee
Robusta coffee is coffee made from beans of the plant Coffea canephora, a sturdy species with low acidity and high bitterness.

Robusta has its origins in central and western sub-Saharan Africa. It is easy to care for, has a greater crop yield, has almost double the amount of caffeine and more antioxidants, and is less susceptible to disease than arabica coffea. It represents up to approximately 40% of global coffee production, with arabica constituting the remainder.
