Understanding Coffee Bean Processing Methods

We often hear terms like washed method, natural method, honey process, and similar classifications. But what impact do these different coffee bean processing methods have on coffee flavor? Today, let's explore this topic in detail.

What are Coffee Cherries?

Coffee trees produce coffee fruits for reproduction. These fruits are bright red and, due to their cherry-like appearance, are commonly known as "coffee cherries."

The coffee beans we use to make coffee are actually the seeds inside the coffee fruit. Surrounding these seeds are structures including the outer skin, pulp, mucilage, parchment, and silver skin. The purpose of processing is to remove these external structures to obtain the internal coffee seeds.

Natural Processing Method

The natural processing method is the oldest technique. According to historical records, Arabs began using this method to process coffee fruits as early as the 11th century, over 1000 years ago. Due to coffee's stimulating effects, when coffee was introduced from the Arab world to the West, it was called "the wine of the Arabs."

Processing Steps

1. Removing Floaters

Coffee beans are poured into large water tanks. Underdeveloped, low-quality beans float to the surface, while mature, full fruits sink to the bottom. The floating beans are then skimmed off, completing this initial step.

2. Sun Drying

Coffee fruits are spread evenly on drying patios and turned several times daily. This process typically lasts 2-3 weeks, depending on local climate. The drying is complete when the moisture content inside the coffee beans reaches 10-14%.

3. Removing Outer Hulls

After drying, the outer layers of the coffee seeds become hard and dry. At this point, hulling machines are used to remove the outer hulls, completing the natural processing method.

Advantages:

Aside from the initial step of removing floaters (which some regions even omit), the natural method doesn't require water, and the water used can be reused. With low costs, this method is widely used in areas with limited water resources and less affluent regions.

Disadvantages:

1. Since coffee beans must remain outdoors for extended periods, impurities such as dead leaves and twigs often mix with the beans.

2. Because it relies on solar energy, the drying level of coffee beans is difficult to control, leading to over-drying situations that can damage the internal coffee beans.

3. During the sun drying process, since the pulp hasn't been removed, mold and rot often occur.

Flavor Profile:

Because the natural method allows coffee fruits to dry naturally, coffee beans can mature naturally inside the fruit without external environmental interference. Therefore, naturally processed coffee beans amplify their inherent flavors, resulting in rich body, intense flavor, and noticeable sweetness.

Washed Processing Method

Due to the numerous disadvantages of the natural method, the washed processing method was developed. The washed method is currently the most widely used processing approach. Its biggest difference from natural processing is the use of fermentation to remove the mucilage layer.

Processing Steps

1. Removing Floaters (same as natural method)

Coffee beans are poured into large water tanks. Underdeveloped, low-quality beans float to the surface, while mature, full fruits sink to the bottom. The floating beans are then skimmed off, completing this step.

2. Removing Outer Skin and Pulp

Using a pulping machine, the outer skin and pulp of the coffee fruits are removed (leaving mucilage, parchment, and silver skin).

3. Fermentation

The purpose of this step is to use biological methods to remove the mucilage. Coffee fruits processed by the pulping machine are placed in fermentation tanks for 16-36 hours, where fermentation bacteria dissolve the mucilage.

4. Washing

After completing fermentation and mucilage removal, fermentation bacteria and impurities remain on the coffee beans, so they are washed again. This step consumes large amounts of clean water to ensure thorough cleaning.

5. Drying and Removing Parchment and Silver Skin

Typically, machines (or sun drying) are used to dry the coffee fruits until moisture content reaches 10-14%. Then hulling machines remove the remaining parchment and silver skin, completing the processing.

Advantages:

1. All processing steps in the washed method are done indoors, minimizing impurities in the coffee beans and ensuring the highest quality.

2. Since the pulp is removed initially, there's no need to worry about mold problems as in the natural method.

3. The appearance is more complete, with excellent visual appeal.

Disadvantages:

1. The process is complex and cumbersome, making it much more expensive than the natural method.

2. It requires large amounts of clean water - producing 1 kilogram of coffee beans consumes 40-50 liters of clean water, making it less common in water-scarce regions.

Flavor Profile:

Due to fermentation, washed coffee beans typically have bright acidity and fruity aromas.

Honey Processed Coffee Beans

The honey processing method is an improved version of the natural method. The main difference from natural processing is that the outer skin and pulp are removed before sun drying, while preserving the mucilage layer for direct sun drying.

Processing Steps

1. Removing Floaters (same as natural method, though some regions may skip this step)

Coffee beans are poured into large water tanks. Underdeveloped, low-quality beans float to the surface, while mature, full fruits sink to the bottom. The floating beans are then skimmed off, completing this step.

2. Removing Outer Skin and Pulp (same as washed method)

Using a pulping machine, the outer skin and pulp of the coffee fruits are removed (leaving mucilage, parchment, and silver skin).

3. Sun Drying

Coffee beans with mucilage are spread on drying patios for direct sun drying until moisture content reaches 10-14%.

4. Removing Mucilage and Parchment

Special machines are used to remove the mucilage and parchment, completing the processing steps.

Advantages:

1. As an improved natural method, the pulp is removed initially, so there are no mold problems.

2. It doesn't require large amounts of clean water, keeping costs relatively low.

Disadvantages:

The processing steps can be considered the most complex and labor-intensive of all methods.

Flavor Profile:

Honey processed coffee beans have excellent flavor with balanced acidity and sweetness. Like the natural method, the sun drying amplifies the coffee beans' inherent aromas, resulting in rich body.

Other Methods

Besides the processing methods mentioned above, there are also techniques that use enzymes and digestive fluids from biological digestive systems to process green coffee beans (simply put, this involves having animals excrete the coffee beans...).

Currently known animals used for this processing include the well-known civet cat (kopi luwak) and elephants (black ivory coffee). Other regions also use monkeys, turkeys, and even water buffalo for coffee processing, but production volumes are low, making these methods rare.

Conclusion

In reality, the green bean processing stage involves various processing methods, with the core content revolving around variations of fermentation.

During the fermentation process, different participating substances (coffee fruit skin, coffee pulp, coffee mucilage, bacterial types, bacterial distribution), different environments (with or without water, aerobic or anaerobic, pH environment, etc.), and different drying methods and processes (container materials, natural sun drying, drying equipment, turning frequency, etc.) create the diverse post-processing flavors and textures we experience. Only by understanding the actual process and development degree of fermentation can one imagine the flavor direction of green beans.
