What is the difference between natural and washed coffee?

Coffee processing is the bridge between the farm and the roastery, and it is arguably the most significant factor in determining the final flavor profile of your coffee. The two most common methods, natural and washed, represent opposite approaches to handling the coffee cherry after it is harvested.

The washed process, sometimes called wet processing, is designed for clarity. Immediately after picking, the skin and pulp of the cherry are removed by a machine called a depulper. The beans, still covered in a sticky layer of mucilage, are then placed in fermentation tanks where natural enzymes break down the remaining fruit. After washing away the residue, the beans are dried. This method highlights the inherent characteristics of the coffee variety and the terroir of the farm, resulting in a 'clean' cup with bright acidity and distinct flavor notes.

Natural processing, or dry processing, is the oldest method and is common in regions with limited water access. In this method, the entire coffee cherry is spread out on drying beds or patios to dry in the sun. As the fruit dries, the sugars and flavors from the pulp and mucilage are absorbed into the bean. This process imparts a heavy, syrupy body and intense, often jammy or wine-like fruit flavors. Because the bean is in contact with the fruit for so long, the resulting cup is often less 'clean' than a washed coffee but significantly more complex and sweet.

Choosing between these two is a matter of preference. If you enjoy a cup that highlights the delicate floral or citrus notes of a specific origin, a washed coffee is usually the best choice. If you prefer a coffee that feels substantial on the palate and offers bold, fruit-forward sweetness, a natural process coffee will likely satisfy your cravings. Many roasters now offer both, allowing you to explore how the same bean can taste entirely different depending on how it was processed.
