Within the genus Coffea, there are an estimated 129 different species — however, just 2 make up about 99% of the coffee consumed worldwide.
Coffea robusta is our preferred bean of choice. It's loved for its high caffeine content (2X that of arabica coffee), potent antioxidant levels (again, 2X that of arabica), and low sugar content. Robusta beans prefer growing at lower altitudes, can withstand droughts, and produce about 3 times as much coffee per year compared to arabica.
Coffea arabica beans are known for their smoother, more acidic, and flavorful profile with a higher concentration of sugars and oils, giving them complex flavor characteristics. Arabica beans require a high altitude and use a lot of water to cultivate.
