History of Arabica Coffee

Origin and Domestication

Arabica coffee, also known as Coffea arabica, is believed to have originated in the highlands of southwest Ethiopia, specifically the Kaffa region. It is said that the name “coffee” is derived from “Kaffa,” referring to the place where it was first discovered. Arabica coffee is an evergreen shrub, which is part of the Rubiaceae family, and can grow up to 5 meters tall. This type of coffee is revered for its distinctive flavor and aroma, which is notably brighter and more complex than other species, such as Robusta or Liberica.

According to historical records and legends, Ethiopian tribes noticed the energizing effects of coffee beans when consumed by animals such as birds and goats. People then began to eat the beans, either as a whole or crushed and mixed with fat, as an energy-boosting snack. Locals would also ferment the coffee cherries to create a type of wine. However, it was not until the 15th century that the berries were roasted and brewed, similar to today’s method of coffee preparation.

In the 6th century, Arab traders traveling to Ethiopia discovered the coffee plant and were intrigued by its effects. They brought beans back with them and began cultivating and experimenting with different preparation techniques. The Arabian Peninsula became the first place outside of Africa where the Arabica coffee plant was successfully domesticated, turning it into a large-scale crop.

The Spread of Arabica Coffee

The spread of Arabica coffee from Ethiopia to other parts of the world began around the 15th century. It is believed that Yemen was the first country outside of Africa where Arabica coffee was cultivated. It was introduced to the country by Sufi monks who used the beverage in their rituals to induce a state of mental clarity during their long hours of night prayers. By the 16th century, coffee drinking had spread across the Arabian Peninsula, becoming an essential part of the Islamic culture.

Coffee gained popularity not only as a beverage but also as a social ritual. Europeans who traveled to the Middle East were introduced to coffee, and by the 17th century, the beverage found its way to European markets. Merchants and explorers accelerated the trade in Arabica coffee beans, planting the seeds along their routes around the world. The Dutch, for example, brought Arabica coffee plants to the East Indies and their colonies in the Americas.

In the 18th century, Gabriel de Clieu, a French naval officer, infamously smuggled an Arabica coffee plant from the Royal Botanical Garden in Paris and transported it to the French colony of Martinique. This single plant became the ancestor of millions of Arabica coffee trees in the Caribbean, South America, and Central America. Today, Arabica coffee is grown in more than 40 countries, making it the most widespread and popular coffee species worldwide.

The Development of the Coffee Industry

The increasing demand for Arabica coffee beans led to its commercial production in various parts of the world.

Harvesting and Processing Arabica Coffee

Arabica coffee, known scientifically as Coffea arabica, accounts for about 60% of the world’s coffee production. The plant is native to the highlands of Ethiopia and has long been cultivated for its beans, which are used to produce a high-quality coffee beverage.

Harvesting Techniques

Harvesting Arabica coffee beans is a labor-intensive process that requires skill and experience. There are two main methods for harvesting Arabica coffee: strip harvesting and selective harvesting. Strip harvesting is a method where all the coffee cherries are removed from the branch at once, regardless of their ripeness.

This can be done either manually, by pulling or shaking the branches, or mechanically, using specialized machines. While this method is faster and requires less labor, it often leads to a lower quality coffee as unripe and overripe cherries get mixed with the ripe ones. Selective harvesting, on the other hand, involves hand-picking only the ripe cherries.

This method produces the highest quality beans but is also the most labor-intensive and time-consuming, as pickers must return to the same trees several times during the harvest season to ensure that all ripe cherries are collected. The quality of the final product depends largely on the skill of the picker.

Primary Processing: Wet and Dry Methods

After harvesting, the coffee cherries undergo primary processing to separate the beans from the fruit. There are two main methods for primary processing: the wet method and the dry method. The wet method involves soaking the cherries in water, which causes the ripe cherries to sink and the unripe ones to float.

The ripe cherries are then put through a pulping machine that removes the outer skin and pulp, leaving only the mucilage-covered beans. The beans are then fermented in water, typically for 12 to 48 hours, to dissolve the sticky mucilage layer. Finally, the beans are washed to remove any remaining residue and are laid out to dry in the sun or in drying machines.

The dry method, also known as the natural or sun-drying method, is simpler and is most commonly used in regions with limited access to water. The coffee cherries are spread out on drying patios or raised beds and left to dry in the sun for several weeks. During this time, the cherries must be turned regularly to ensure even drying. Once the cherries are fully dried, the outer layers are removed using hulling machines.

Secondary Processing: Roasting Techniques

Roasting is an essential step in coffee processing that transforms the green coffee beans into the aromatic, flavorful product enjoyed by millions worldwide. There are various roasting techniques and machines used to achieve the desired flavor profiles, including drum roasters, air roasters, and combination roasters.

The temperature, duration, and airflow during the roasting process significantly impact the coffee’s final flavor. Beans are generally roasted at temperatures between 350°F and 520°F (175°C and 270°C) and are usually roasted for 10 to 15 minutes. During roasting, beans undergo chemical reactions, such as caramelization and the Maillard reaction, which produce the familiar coffee aroma and flavors.

Quality Control and Grading

Quality control is crucial in Arabica coffee production to ensure a consistent and high-quality product. Coffee quality is affected by various factors, including harvesting methods, processing techniques, environmental conditions, and storage practices.

To maintain a standardized quality for Arabica coffee, the Specialty Coffee Association (SCA) has established a grading system based on factors such as bean size, shape, color, moisture content, and the presence of defects. Coffee is usually graded by trained professionals, called “cuppers,” who evaluate the coffee’s sensory attributes by cupping or tasting sessions.
