Coffee cherries, the fruits of the coffee plant, are harvested when they reach the desired level of ripeness. Typically, coffee cherries are picked by hand, ensuring that only the fully ripe cherries are selected. This labor-intensive process requires skilled workers who can accurately identify the right cherries to pick.

There are two primary methods of coffee cherry harvesting:

Strip Picking

In strip picking, all the cherries are harvested from the coffee tree at once, regardless of their ripeness. This method is often used in regions with lower labor availability, as it allows for a quicker harvest. However, the downside is that it can result in a mix of ripe and unripe cherries, which affects the quality of the final product.

Selective Picking

Selective picking involves handpicking only the ripe cherries, leaving the unripe ones on the tree to ripen further. This method requires careful inspection and repeated visits to the same tree since cherries ripen at different rates. Although selective picking is a time-consuming process, it ensures that only the highest-quality cherries are harvested, resulting in a superior cup of coffee.

Processing Methods For Coffee Beans

Once the coffee cherries are harvested, they go through a series of processes to separate the beans from the fruit. The specific processing method employed can have a significant impact on the final flavor profile of the coffee. There are three primary processing methods:

Washed Process

The washed process, also known as the wet process, involves removing the outer skin and pulp of the cherry immediately after harvesting. The cherries are then submerged in water, allowing fermentation to occur. During fermentation, enzymes break down the remaining layers of the cherry, leaving only the coffee beans.

After fermentation, the beans are typically washed and rinsed to remove any remaining impurities. They are then dried either in the sun or using mechanical dryers. The washed process is known for producing a clean and bright cup of coffee, highlighting the inherent flavors of the beans.

Natural Process

The natural process, also known as the dry process, involves drying the coffee cherries whole, with the fruit still intact. After harvesting, the cherries are spread out on drying beds or patios to dry naturally under the sun. As the cherries dry, they shrink, allowing the beans to separate from the fruit.

Throughout the drying process, it is crucial to regularly turn the cherries to ensure even drying and prevent fermentation. The natural process often results in a sweeter and fruitier cup of coffee, with pronounced flavors and a fuller body.

Honey Process

The honey process, also known as the pulped natural process, is a hybrid of the washed and natural methods. In this method, the outer skin of the cherry is removed after harvesting, but the sticky mucilage layer is left intact. The cherries are then spread out to dry.

During the drying process, the mucilage ferments and imparts additional sweetness and complexity to the coffee beans. The honey process can produce a range of flavor profiles, depending on the drying time and amount of mucilage left on the beans. It often results in a cup of coffee with a balanced acidity, sweetness, and body.

Drying And Sorting The Beans

After the coffee beans have been processed, they need to be properly dried to reduce their moisture content. This crucial step ensures the beans can be stored without spoiling and preserves their quality until they are ready for roasting. Several drying methods can be employed:

Sun Drying

Sun drying is the traditional method of drying coffee beans and involves spreading them out in thin layers on large patios or drying beds. The beans are raked regularly to ensure even drying and to prevent over-fermentation.

Sun drying can take between one to three weeks, depending on the weather conditions. It is essential to dry the beans slowly to preserve their flavor and prevent them from developing any off-flavors caused by rapid drying. Once the beans reach the desired moisture content, they are stored in protective bags until they are ready for shipment.

Mechanical Drying

In regions where the weather is unpredictable or unsuitable for sun drying, mechanical dryers can be used. These dryers use heated air or a combination of heat and air circulation to remove moisture from the beans.

Mechanical drying offers more control over the drying process, allowing for shorter drying times and reducing the risk of spoilage. However, it is crucial to monitor the temperature and airflow carefully to prevent the beans from overheating or developing off-flavors.

After drying, the coffee beans go through a sorting process to remove any defects or impurities. This step is crucial for ensuring the consistent quality of the beans. The sorting can be done manually or using mechanical sorting machines. The beans are inspected for color, size, and shape, and any defective or unripe beans are removed.

Growing coffee beans is a complex and intricate process that requires careful attention to detail at every stage. From ensuring the plants receive adequate water through irrigation to selecting and harvesting ripe cherries, each step plays a crucial role in producing high-quality coffee.

The processing methods, such as the washed, natural, and honey processes, further contribute to the unique flavors and characteristics found in different coffee varieties. Finally, the careful drying and sorting of the beans ensure they are ready for roasting and ultimately, brewing the perfect cup of coffee.
