What is the difference between the different varieties of coffee plants?
All coffee beans come from plants in the genus Coffea. Within this genus are many species of plants; however, only two are of commercial importance, i.e., Coffea arabica, and Coffea canephora, the latter more commonly called robusta. Arabicas are considered the more flavorful, with lower content and is usually grown in higher elevations primarily in mountainous terrains with appropriate shading. Robustas are grown on vast plains and have higher caffeine content.
