Arabica vs. Robusta Coffee - What's the Difference?
When you choose your daily coffee, you probably don’t think a whole lot about the type of coffee beans used to produce it. Ultimately, you think that all coffee beans look the same when roasted. There are actually twenty-five different species of coffee beans in the world, with the two primary ones used for cultivation being Arabica and Robusta. There are key differences between the two, not just in terms of flavor, but also in characteristics and growing conditions. Since Arabica and Robusta are the most important coffee bean types, we’re here to help you gain a thorough understanding of those differences. Growth: Since they are well suited to warm, tropical climates, Arabica trees flourish when the air is heavy with humidity. Arabica coffee trees grow at altitudes as high as 7,000 ft. above sea level, and usually take up to 7 years to fully mature. These trees do best at temperatures of 59-75° F, and can yield anywhere from 1 pound to 11 pounds of coffee per growing season. Flavor: Arabicas generally have a range of tastes from soft and sweet, to fruity and zesty. There are actually different types of Arabica coffee beans called cultivars, all of which are known for their different flavors and attributes. Physical Characteristics: Arabica beans are flatter and more elongated, and are deep green, almost blue in color prior to roasting. Growth: In comparison with Arabica, Robusta trees can be grown in more flexible temperatures, but they are also best suited to humid, tropical climates. Robusta grow best at altitudes of 0-2,300 ft. above sea level and at temperatures of 75-86°F. While Robusta require more rainfall, they are cheaper to cultivate, as they do not require several cycles of pesticide and herbicide treatment, and produce higher yields. Flavor: Robusta coffee is known for its strong, “robust”, earthy flavor, and its acidity. These coffee beans contain more acid and caffeine content than any Arabica. They are used as caffeine boosters as well as fillers to improve the taste of flat or weak tasting coffee. When Robusta is treated with the same amount of care given to Arabica coffee, it can attain better refinement to yield a milder flavor than usual. Physical Characteristics: Robusta beans are flat, but not as much as Arabica, and are more rounded. They are pale green with a bit of brown or grey prior to roasting.
