How are coffee beans grown?

Coffee beans go through a series of steps before they reach our cups. The process begins with planting coffee seeds, which are actually coffee beans. These seeds are typically planted in shaded nurseries and watered frequently until they are ready to be permanently planted. After about 3 to 4 years, the coffee trees bear fruit known as coffee cherries. The cherries turn red when ripe and are harvested either by stripping all the cherries off the branch at once or selectively picking only the ripe ones. The harvested cherries are then processed either through the dry method, where they are spread out in the sun to dry, or the wet method, where the pulp is removed before drying. Once dried, the beans are milled, sorted, and graded by size and weight. Finally, the beans are ready for export. The entire process from planting to exporting can take months, and it involves careful attention to detail to ensure the best quality beans.

Key Takeaways:

• Coffee beans begin as seeds that are planted in nurseries
• Coffee trees bear fruit known as coffee cherries
• Coffee cherries are either stripped off the branch or selectively picked
• Processed through the dry or wet method
• Beans are milled, sorted, and graded before being exported

Whether you are sipping a cup of coffee in the morning or enjoying an espresso in the afternoon, it is always fascinating to learn about the journey that coffee beans undertake to reach our mugs. From planting the seeds to harvesting the cherries, each step in the coffee farming process contributes to the distinct flavors and aromas that we enjoy. Let’s dive deeper into the cultivation of coffee beans and explore the life cycle of a coffee tree.

Where does coffee come from?

Coffee, one of the world’s most beloved beverages, has an intriguing origin rooted in the tropical regions known as the Bean Belt. This belt stretches across Central and South America, Africa, the Middle East, and Asia, encompassing diverse coffee-growing regions. It is within these regions that the coffee plant, a woody evergreen, thrives and bears the cherished fruits we know as coffee cherries.

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.

Key Points:

• Coffee originates from the Bean Belt region, which spans Central and South America, Africa, the Middle East, and Asia.
• Coffee cherries develop on the coffee plant, a woody evergreen.
• Cherries change color as they mature, with flavors and qualities varying based on their ripeness.
• Arabica and Robusta are the two primary coffee species, each offering distinct flavors and characteristics.

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.
