Understanding Natural Process Coffee Beans

Natural process coffee beans, put simply, are coffee cherries dried in the sun with their pulp and skin intact—which is why they are called "Natural" in English. But this natural method, simple as it looks, is not as easy as it appears, and refining it has taken a great deal of effort.

Traditional vs. Modern Natural Processing

The commercial form of natural processing involves laying plastic sheets on the ground and placing coffee beans directly on them to dry in the sun. This method suffers from heat transfer from the ground and unstable thermal convection in the cherry pile. Without frequent turning, the temperature can rise too high or fermentation can become uneven. (Picture the beans on top drying comfortably while the ones underneath develop off-flavors from being trapped.) In addition, many harmful microorganisms and contaminants on the ground can damage the beans' flavor, so traditional natural processing often yields unpredictable results. In the past, high-quality beans were not processed this way, because the reputation was poor and prices were low.

Natural processing has improved significantly in recent years, however. Modern natural processing mostly uses African-style raised beds, which effectively block ground moisture and soil while increasing air convection. During the process, temperature is also strictly controlled to prevent excessive fermentation caused by heat.

The whole natural process typically takes more than 20 days, allowing microorganisms and cherry pulp to ferment gradually, producing sweeter flavors that are often rich in tropical fruit notes.

Historical Background

Natural processing is the oldest processing method. According to the literature, Arabs were already using natural processing on coffee fruit as early as the 11th century, over 1,000 years ago. Because of coffee's stimulating effect, when it was introduced from the Arab world to the West it was called "Arabian wine."

Processing Steps

1. Removing Floating Beans

The coffee beans are poured into large water tanks. Underdeveloped, inferior beans float to the surface, while mature, full fruit sinks to the bottom. The floating beans are then scooped off, completing this step.

2. Sun Drying

The coffee fruit is spread evenly across drying beds and must be turned several times a day. This usually lasts about 2-3 weeks, depending on the local climate. When the moisture content inside the beans drops to 10-14%, the sun-drying step is complete.

3. Removing the Outer Shell

Once sun drying is complete, the outer layer of the coffee seed has become dry and hard. A hulling machine is then used to remove that outer shell, completing the natural process.

Advantages

Apart from the floating-bean removal step, natural processing needs no water, and one bucket of water can be reused many times. Costs are low, so it is widely used in regions with limited water resources and less affluence.

Disadvantages

1. Because natural processing takes place outdoors, impurities such as dead branches and fallen leaves often get mixed in.
2. Because it relies on solar energy, the degree of drying is hard to control, leading to "over-drying" in which the fruit is damaged and the beans inside break.
3. During the process the pulp is not removed, so mold and rot are common.

Flavor Profile

Because natural processing lets the fruit dry naturally, the beans mature inside the fruit without interference from the outside environment. Natural-processed beans therefore amplify their inherent flavors, giving a rich body, intense flavors, and noticeable sweetness.

FrontStreet Coffee Recommendation

Natural processing is Ethiopia's signature, and FrontStreet Coffee's natural Ethiopian line is a great place to taste what it can do. The FrontStreet Yirgacheffe Natural Red Cherry starts with damaged and moldy fruit removed, then dries in the sun for about two weeks until the sugars and essence seep into the bean and moisture falls to 12%. The result is a clean, fruit-forward cup of peach, cocoa, honey, and lemon. For the flagship Sidamo expression, the FrontStreet Huakui comes from the Hambela area of Guji, dried on raised beds for 21 days with regular turning and hand sorting; medium-light roasted, it shows a soft fermented wine note, florals, citrus, and mango, with honey sweetness, a cocoa finish, and a thick, lingering body.

If you enjoy the floral side of natural Ethiopian coffee, the FrontStreet Kafa Forest is medium-light roasted for prominent white florals, bright lemon acidity, sweet orange, and bergamot, with a faint melon and nut sweetness and a green-tea-like texture on the finish. Each of these beans is a fine demonstration of the natural process described above.
