What is the natural process step-by-step?
The , or dry process, involves drying harvested coffee cherries whole, with the fruit skin and pulp intact, before removing the outer layers. This traditional method allows the coffee bean to absorb sugars from the fruit during drying, resulting in a heavy-bodied, sweet, and fruit-forward cup profile that is highly prized in production.
Sources show where the underlying information came from. They do not automatically make a claim correct, so disputed history, evolving science and uncertain claims should be labeled as such in the explanation itself.
The is the oldest and most traditional method of coffee production. Unlike the , which removes the fruit immediately, the keeps the entire intact from the moment it is harvested until it reaches a specific moisture content. This simplicity makes it a staple in regions with limited water access, such as parts of Ethiopia and Brazil.
After harvesting, the cherries are sorted to remove unripe or damaged fruit, often using flotation tanks. The selected cherries are then spread in thin layers on raised beds or patios to dry under the sun. During this period, which can last several weeks, the cherries must be turned frequently to ensure even drying and prevent fermentation defects or mold. As the fruit dries, it shrinks and darkens, concentrating the sugars and flavors within the bean.
Once the cherries reach a target moisture level—typically around 11% to 12%—they are considered stable. At this stage, the dried, brittle fruit is sent to a for . The machine mechanically removes the dried skin and pulp, revealing the bean inside. These beans are then graded, sorted, and prepared for export.
In practice, the imparts a distinct sensory profile to the coffee. Because the bean spends weeks in contact with the fruit's and sugars, the resulting cup often features bold, winey acidity and intense fruit notes like blueberry, strawberry, or tropical fruit. It is a method that highlights the of the farm, as the extended contact time allows the bean to absorb the unique characteristics of the fruit.
For the consumer, understanding this process explains why some coffees taste like fruit juice while others taste like clean, crisp tea. When you see '' on a bag, you can expect a heavier body and a more complex, sweet profile. It is a testament to how post-harvest handling is just as critical as the in determining what you taste in your morning cup.
