Extraction plays the most important role in brewing a cup of coffee. Whether it's pour-over drip, espresso, or any other brewing method, extraction has a significant relationship with it. Extraction is the key point in making a cup of coffee. Single origin coffee brewing methods are very diverse: siphon, pour-over, AeroPress, and more.

Natural Process

Natural processing has very high requirements for climate. If it encounters rainy days during the drying process, the beans will become damp and moldy. Natural processed beans have a yellowish color when raw, and the center line will appear brown after roasting, rather than the white of washed beans.

Natural processed beans generally have better sweetness and body, with less acidity, but their quality is less stable with greater variations. Due to the lower cost of natural processing, it is not only widely used in Ethiopia and Yemen, but Robusta coffee grown in Africa and Indonesia is also generally processed using the natural method.

Washed Processing

Washed processing can remove impurities (stones or garbage) and defective beans through each step, resulting in uniform appearance of raw beans. It is generally considered to have high quality, and the trading price is also higher than coffee beans refined by the natural drying method.

However, the more detailed the work division, the more procedures involved in operation and hygiene management, and the higher the risk. Therefore, washed processing does not necessarily equal high quality. The biggest disadvantage of washed coffee is that during the fermentation process, coffee beans are easily contaminated with fermentation odor. Washed processed coffee has bright acidity and clean taste.

Honey Processing

Honey processing is the production process of raw beans that are sun-dried with mucilage. After removing the outer pulp of coffee beans, there will be a layer of viscous gelatinous substance. Traditional washed processing uses clean water to wash it away, but due to water resource limitations in some high-altitude producing areas, this direct drying method emerged.

The honey processing process is easily contaminated and affected by mold, requiring careful supervision throughout, constant turning, and accelerated drying to avoid undesirable fermentation flavors. Its advantage is that it best preserves the original sweet flavor of ripe coffee fruits, giving the coffee a subtle brown sugar flavor and nut sweetness, while berry flavors also support a red wine-based aroma, considered a very elegant product.

Knowledge Expansion

In the world of pour-over coffee, restoring the bean's flavor as much as possible and making it delicious is the most important thing. Every step to achieve this goal can be full of creativity, so there are many brewing techniques, which we often call pour-over schools or styles.
