                                Globally, Robusta beans make up about 30-40% of the coffee market, yet they contain nearly twice the caffeine of their more popular counterpart, Arabica. If you're wondering what type of bean has the most caffeine, the answer is definitively Robusta, but the story is far more complex than a simple head-to-head competition.
