Within the coffee cherries, the extraordinary transformation from flower to coffee bean takes place. These cherries undergo a mesmerizing array of colors as they mature, transitioning from vibrant green to hues of red, orange, yellow, or pink, depending on the variety. When the cherries reach the optimal level of ripeness, they are carefully handpicked or mechanically stripped from the coffee plants.

To gain a deeper appreciation for the wide spectrum of coffee flavors and qualities, it’s important to understand the two primary types of coffee species: Arabica and Robusta. The Arabica family dominates the coffee production landscape, known for its exceptional flavors, delightful aromas, and delicate acidity. On the other hand, the Robusta species offers a bolder flavor profile with earthy and bitter notes, along with a higher caffeine content.

How do coffee plants grow?

When it comes to coffee plants, their growth is truly remarkable. These evergreen trees or shrubs can reach impressive heights of up to 10 meters in their natural habitat. With their dark green, waxy leaves, coffee plants play a vital role in a process called photosynthesis, where they convert sunlight into energy.

Coffee cherries, the fruits that contain coffee beans, grow on the branches of coffee plants. This typically happens after a period of 3-5 years of growth. To facilitate reproduction, coffee plants produce small, fragrant white flowers that house their sex cells. The cherries then develop in the same spot where the flowers were and undergo a color transformation as they mature.

Protecting coffee plants from direct sunlight is crucial. In their natural habitat, coffee plants thrive under the shade of taller plants in the forest canopy. This shade not only provides necessary protection but also contributes to the distinct flavors found in coffee beans. Therefore, careful pruning of the plants is necessary to maintain a desirable height and facilitate ease of harvesting.

Coffee plants have specific requirements to grow optimally. They prefer specific temperature and rainfall conditions, typically found in tropical regions. Additionally, coffee plants thrive at higher elevations, further contributing to the unique characteristics of their beans. Meeting these requirements through careful cultivation practices ensures the best growth and flavor development in coffee beans.

Coffee Plant Characteristics:

  • Evergreen trees or shrubs
  • Can reach heights of up to 10 meters
  • Dark green, waxy leaves
  • Produce small, fragrant white flowers
  • Develop coffee cherries where flowers were located
  • Require shade and protection from direct sunlight
  • Annual pruning for height maintenance and easier harvesting

The harvesting process requires a delicate touch and a keen eye to select only the best cherries for further processing. Skilled labor is instrumental in ensuring that the maturation process is respected, and only fully matured cherries are chosen. This attention to detail during coffee cherry picking contributes to the overall quality and flavor of the coffee beans.

Coffee processing and the journey to your cup

After the coffee cherries are picked, they need to be processed quickly to prevent spoilage. There are two main methods of coffee processing: the dry method and the wet method.

Dry Method:

The dry method involves spreading the cherries on large surfaces to dry in the sun. This traditional method is commonly used in regions with little rainfall and ample sunlight. The cherries are laid out on raised beds or patios, where they are left to dry for several weeks. During this time, the cherries are regularly turned to ensure even drying. The heat of the sun and the natural airflow facilitate moisture evaporation, resulting in dry coffee beans.

Wet Method:

The wet method, also known as washed processing, involves removing the pulp from the cherries before drying. After harvesting, the cherries are pulped to separate the bean from the fruit. The beans are then soaked in water, allowing fermentation to break down the remaining pulp. After fermentation, the beans are thoroughly washed to remove any remaining impurities. Finally, the washed beans are dried either on raised beds or using mechanical dryers, depending on the processing facility. The wet method is favored in regions with abundant water resources and a focus on producing cleaner, more vibrant flavors.

Coffee Bean Milling:

Once the coffee beans have been dried to the desired moisture content, they undergo the milling process. Milling involves removing the parchment layer, which surrounds the bean and protects it during drying. The beans are passed through machines that remove the parchment, leaving behind the green coffee beans. This step is crucial in preparing the beans for further processing and eventual export.

Coffee Bean Grading:

After milling, the green coffee beans are sorted and graded based on their size and weight. This ensures consistency in the quality of beans and allows buyers to make informed choices. Grading is typically done through manual or mechanical sorting, where defective beans, such as those with insect damage or defects, are removed. The grading process plays a vital role in determining the value and marketability of the coffee beans.

Coffee Bean Export:

Once the beans have been dried, milled, and graded, they are ready for export to various destinations around the world. Green coffee beans, as they are known at this stage, are loaded onto ships that transport them to coffee roasters and distributors globally. The journey from coffee plant to coffee cup involves multiple stages of processing and quality control measures to ensure that only the best beans make it to the consumer.
