Arabica and Robusta: The Two Main Coffee Species
Characteristics of Arabica
Arabica (Coffea arabica) is one of the two main species of coffee and accounts for about 55% of global coffee production. It is indigenous to certain parts of Africa and is primarily grown in high-altitude regions between 3,000 and 6,000 feet. The growth of coffee cherries in these elevated conditions, characterized by hot days and cool nights, is slow, allowing the cherries and the coffee beans inside to develop complex and refined flavors.
Arabica beans are generally flatter and more elongated compared to robusta beans. When brewed, arabica coffee is often considered milder, more flavorful, and more aromatic than its robusta counterpart. Although arabica is more widespread in cultivation, it is more delicate and vulnerable to pests, necessitating cool and temperate growing conditions.
Characteristics of Robusta
Robusta (Coffea canephora) is the other main species of coffee, comprising about 45% of the world's coffee production. Unlike arabica, robusta plants are more resistant to pests and are typically grown at lower altitudes, making them suitable for a wider range of growing conditions.
Robusta beans are rounder and smaller than arabica beans, and when brewed, they produce a stronger, more bitter taste. This characteristic is due to the higher caffeine content in robusta beans – nearly twice the amount found in arabica beans. This high caffeine content also contributes to robusta's natural resistance to pests and diseases.
In summary, not all coffee is arabica. There are two main species of coffee: arabica and robusta. Arabica coffee is generally considered to have a milder, more complex flavor profile, while robusta coffee is stronger and more bitter. Both species have distinct characteristics and growing conditions, offering a variety of flavors for coffee enthusiasts to enjoy.
History and Origins of Arabica Coffee
Arabica coffee, scientifically known as Coffea Arabica, has a rich history that dates back to the 7th century. The plant species got its name when the bean crossed the Red Sea from Ethiopia to present-day Yemen and lower Arabia. It was in the Arab world where coffee made from roasted beans was first documented for its ability to prolong scholars' working hours.
Coffea Arabica is believed to be the first species of coffee to have been cultivated, and today it represents around 60% of global coffee production. Wild coffee plants are thought to have originated from an Ethiopian plateau region named Kefa, or Kaffa. However, the exact details of the plants' origin and domestication remain a mystery.
One popular legend about the discovery of coffee involves Kaldi, a goatherd who found his goats unusually energetic after consuming berries from a wild coffee plant. Intrigued, he experimented by boiling the berries and creating the first coffee brew. This story illustrates both the curiosity and resourcefulness of early humans when they stumbled upon the potent properties of the Arabica coffee bean.
Recent research conducted by scientists found that Coffea Arabica likely derived from a single speciation event, which involved a spontaneous coupling of two different species: Coffea canephora and Coffea eugenioides. Therefore, all Arabica coffee grown around the world today can be traced back to this unique event.
In conclusion, Arabica coffee is not the only type of coffee, as other species like Coffea canephora, which is also known as Robusta, make up a significant portion of global coffee production. While Arabica remains the dominant cultivar due to its less acidic and slightly sweeter taste, the history and origins of this coffee species provide a fascinating insight into the development of one of the world's most beloved beverages.

Processing and Roasting of Arabica Beans
Different Processing Methods
Arabica coffee beans' flavor profiles can vary greatly, from floral and citrus notes to spicy and chocolatey undertones. Factors influencing these flavors include bean variety, growing conditions, processing methods, and roasting techniques. To ensure high-quality coffee, proper processing and roasting are crucial.
When it comes to processing Arabica beans, there are a few common methods. The first is the wet processing method, in which coffee cherries are pulped, and the beans are soaked in water, thus fermenting and separating them from the remaining fruit. This process results in a cleaner, brighter flavor in the final coffee.
Another method is dry processing, where coffee cherries are spread out and left to dry in the sun. Once thoroughly dried, the fruits are mechanically removed, leaving behind the beans. This method creates a richer, heavier-bodied coffee with a fruity sweetness.
The honey processing method involves a combination of wet and dry processing. The skin and most of the pulp are removed from the cherries, but the sticky mucilage, or "honey," coating is left on the beans while they dry. This process imparts a sweeter taste and smoothness to the coffee.
Roasting Techniques
Proper roasting is essential to unlock the potential of Arabica beans' flavors. Roasting involves heating the beans, which initiates a series of chemical reactions that enhance the beans' aroma and flavor. There are three main stages of roasting: the drying phase, the Maillard reaction, and the development stage.
In the drying phase, Arabica beans are heated until the residual moisture evaporates. This usually takes around 4-8 minutes, depending on the roasting technique and equipment. The beans begin to lose moisture and turn from green to a pale yellow color.
The Maillard reaction occurs when the beans reach temperatures between 300°F - 350°F (150°C - 175°C). At this point, the beans turn brown, and the sugars, proteins, and amino acids inside them react to produce complex flavor compounds.
Lastly, the development stage focuses on fine-tuning and perfecting the roast. During this stage, the beans crack and expand due to the release of carbon dioxide and the formation of unique aromatic oils. The roaster carefully manages the temperature and time to create the desired flavor profile.
There are various roasting levels, from light to dark, each with its unique set of characteristics. Light roasts preserve more of a bean's origin flavors, while dark roasts tend to emphasize the roast's bold and robust characteristics. It's crucial to balance the roasting process to ensure the desired flavors and aromas shine through while avoiding over or under-roasting.
In conclusion, the processing and roasting of Arabica beans are critical steps in creating an enjoyable coffee experience. By understanding these methods and techniques, coffee enthusiasts can appreciate the intricate flavors and qualities of Arabica coffee.
