Not all beans are created equal.
There are hundreds of different coffee species, the two most common being robust and arabica. Robusta is a hardier plant that grows at lower altitudes and produces stronger beans with a higher caffeine count. The arabica plant grows at higher altitudes and produces beans with a smoother, more elegant flavor and slightly less caffeine. The popularity of this amazing bean has remained strong as more and more people drink coffee for its invigorating effects and satisfying flavor.
