History of Arabica Coffee

The story of Arabica coffee is as rich and deep as its flavor profile. From its ancient roots to its proliferation across the globe, the journey of Arabica coffee beans is intertwined with the history of human civilization.


Arabica coffee is believed to have its origins in the ancient coffee forests of Ethiopia. According to legend, a 9th-century Ethiopian goat herder named Kaldi discovered the coffee bean after noticing that his goats became energetic after eating the berries from a certain tree. He shared this discovery with a local monk, which eventually led to the brewing of the first coffee. The scientific name of Arabica coffee, Coffea arabica, is a testament to its ancient roots.

Spread to Yemen and Beyond

Arabica coffee’s journey beyond Ethiopia began around the 15th century when it was introduced to Yemen. Yemen’s port city of Mocha emerged as a bustling coffee trade center. The beans were soon cultivated in Yemeni soil, and the country became synonymous with high-quality coffee. By the 17th century, Arabica coffee had spread to the rest of the Arabian Peninsula, including Saudi Arabia and Persia.

European Introduction and Global Expansion

The love for Arabica coffee reached European shores by the 17th century. Initially greeted with suspicion, coffee soon became a staple in European society. The opening of coffee houses, which came to be known as “penny universities” due to the intellectual discussions they housed, marked the beginning of Europe’s coffee culture. The global expansion of Arabica coffee was further propelled by European colonization, as colonists established coffee plantations in various parts of Africa, Central and South America, and Asia.

Modern-Day Proliferation

Today, Arabica coffee beans are grown in a multitude of regions across the globe, with Brazil, Colombia, and Ethiopia being the largest producers. The global love affair with Arabica coffee continues to flourish, with countless coffee enthusiasts and connoisseurs cherishing the rich, nuanced flavors that only Arabica beans can offer.

Processing Arabica Coffee

The journey of Arabica coffee beans from the farm to your cup is a meticulous process that significantly impacts the flavor, aroma, and quality of the coffee. This journey comprises several stages, including harvesting, processing, and roasting.


  • Timing: The harvesting of Arabica coffee beans is a timely affair. It’s crucial to harvest the beans when they are ripe, typically when they turn a bright red color. Early or late harvesting can affect the flavor and quality of the coffee.
  • Methods: Harvesting can be done either by hand or mechanically. Hand-picking is a labor-intensive method but allows for a better selection of ripe cherries. Mechanical harvesting is faster but less selective.


  • Dry Processing: In dry processing, the whole coffee cherry is dried in the sun or using mechanical dryers. Once dried, the outer layers are mechanically removed to obtain the green coffee beans.
  • Wet Processing: This method involves removing the outer skin of the cherry and fermenting the remaining pulp to separate the beans before drying them. It’s a method that tends to produce coffee with a bright, clean profile.
  • Honey Processing: A hybrid method where some mucilage is left on the beans during drying, resulting in flavor profiles that are a mix of dry and wet-processed coffee.
  • Decaffeination: For those who prefer decaffeinated coffee, Arabica beans undergo a decaffeination process to remove caffeine while attempting to retain the bean’s original flavors.


  • Roast Levels: Arabica coffee beans can be roasted to various levels, from light to dark. The roast level significantly affects the flavor, with light roasts preserving more of the bean’s original flavor and dark roasts giving a stronger, more robust flavor.
  • Roasting Process: The roasting process involves heating the beans at high temperatures, which causes chemical changes that develop the flavors and aromas of the coffee. The duration and temperature of roasting are fine-tuned depending on the desired roast level.
  • Cooling and Packaging: Once roasted, the beans are cooled and often packaged as whole beans to preserve freshness. Grinding is usually done just before brewing to maintain the flavor integrity.

The processing of Arabica coffee is an art and science that demands precision and expertise. Each step, from the meticulous harvesting to the careful roasting, contributes to the unique flavor profiles of Arabica coffee. The dedication to quality processing is what allows coffee enthusiasts to enjoy a cup of Arabica coffee with its rich array of flavors and aromas, providing a delightful experience with each sip.
