Takeaways

• 😀 The script discusses four common post-harvest processing methods for coffee green beans in Indonesia: semi-wash, full-wash, honey, and natural processes.
• 😀 Semi-wash processing involves picking ripe coffee cherries, soaking them briefly (6-12 hours), separating floating beans, and using a pulper machine to remove the fruit before drying the beans.
• 😀 Full-wash processing requires a longer soaking period (12-36 hours) and similarly separates floating and sinking beans. The beans are pulped, cleaned, and dried before being hulled.
• 😀 Honey processing involves picking ripe cherries, pulping them with a machine, and leaving some of the fruit’s pulp (honey) attached to the beans during drying. The beans are then dried for 2-4 weeks.
• 😀 Natural processing skips washing and involves drying the whole cherry (including the pulp) for 1-2 months, which can result in a distinct fruity flavor profile.
• 😀 The color of green beans can indicate the type of processing used: semi-wash beans are dark green, full-wash beans are yellowish, honey beans have a brownish hue, and natural beans are typically yellowish.
• 😀 Semi-wash beans tend to have a strong body and a balanced bitterness, while full-wash beans are lighter in body and have a higher acidity with a clean taste.
• 😀 Honey-processed beans feature a strong body, high sweetness, and pronounced acidity, often with distinct fruity flavors.
• 😀 Natural-processed beans have a medium body with low acidity and are often sweeter than honey-processed beans, with flavor notes reminiscent of dried fruits.
• 😀 The coffee's final quality, including flavor and appearance, is influenced by the processing method, as well as the care taken during drying and the impact of weather conditions like rain and humidity.

Q & A

What are the four common post-harvest processing methods for green coffee beans in Indonesia?

The four common post-harvest processing methods for green coffee beans in Indonesia are Semi-Wash, Full-Wash, Honey Process, and Natural Process.

How can you identify green beans processed through the Semi-Wash method?

Green beans processed through the Semi-Wash method have a dark green color, which is a sign of freshness and quality.

What is the general process for Semi-Wash coffee beans after they are picked?

After picking the ripe coffee cherries, they are soaked in water for 6 to 12 hours to separate the good beans from the bad ones. Then, they are pulped to remove the fruit skin, cleaned to remove any residual mucilage, and dried until the moisture content reaches 12-13%.

How does the Full-Wash process differ from the Semi-Wash process?

The Full-Wash process involves soaking the coffee cherries for a longer period (12 to 36 hours) compared to the Semi-Wash process, and it also includes more rigorous washing and separation of floating and sinking beans. The drying time and processing are also more extended.

What are the characteristics of green beans processed using the Full-Wash method?

Green beans processed through the Full-Wash method tend to have a lighter body, a higher acidity, and a more pronounced clean taste, with a lower bitterness compared to Semi-Wash beans.

What is unique about the Honey Process, and how does it differ from the Semi-Wash and Full-Wash methods?

The Honey Process retains part of the coffee cherry's pulp during processing, which contributes to a higher sweetness and more complex flavors. Unlike Semi-Wash and Full-Wash, Honey Process beans are not fully washed and include varying amounts of cherry pulp.

How does the drying time affect the final flavor of coffee beans processed through the Honey method?

The drying time for Honey Process coffee beans can last anywhere from 2 to 4 weeks, and the exposure to the cherry's mucilage during this period contributes to the development of sweet and fruity flavors. The longer the drying period, the richer the flavors, but this also depends on the weather.

What distinguishes the Natural Process from the other methods?

In the Natural Process, the entire cherry is dried with its fruit intact, which can take 1 to 2 months. This method tends to produce beans with more intense fruity flavors and a medium body. It is more dependent on weather conditions and can be prone to mold if not carefully monitored.

Why is climate an important factor for both the Honey and Natural processes?

Both the Honey and Natural processes are highly dependent on climate conditions, as consistent weather is necessary for even drying. Humid or rainy conditions can lead to mold, while dry conditions speed up the drying process.

How do the different post-harvest processing methods affect the flavor profile of the coffee beans?

The processing method greatly influences the flavor profile. Semi-Wash beans tend to have a balanced flavor with strong body and bitterness. Full-Wash beans are lighter with higher acidity. Honey Process beans offer a balance of sweetness and body, while Natural Process beans have fruity, sweet flavors with a medium to full body.
