Difference between Robusta Coffee and Arabica Coffee

Arabica is more popular as a drink in comparison to Robusta mainly because of the taste. Robusta is robust and has almost double the caffeine than Arabica but this higher caffeiene content results in inferior taste.

Around 20-25% of all the coffee produced around the world is Robusta while rest is Arabica; since rest of the varieties grown have negligible production.
