Introduction to the treatment of high-quality coffee beans encyclopedia coffee

I believe that when you browse the menu of single-item coffee in cafes on weekdays,

Often you will see descriptions of "treatment" such as "washing,""solarization,""honey treatment," etc.

What exactly is the "treatment"?

"Process" refers to the various practices used in the manufacturing process of green coffee beans.

More specifically, it is aimed at how to remove the exocarp and pulp of ripe coffee cherries,

To just raw beans.

Red Catuai & Yellow Catuai Ripe Coffee Berries Sunburn> Peeling and Shelling

In the earliest days, coffee processing began with sun exposure;

The process of solarization is relatively simple for the early stage,

Send the whole cherry berry directly to the sun for sun exposure

After reaching the ideal dry humidity, peel and peel again.

African origin because of lack of water resources, so more popular this method

Sunlight flavor: more miscellaneous flavor, high sweetness

Intermediate: Washed Process

Process: Bean-picking> Peeling> Fermentation> Cleaning> (Secondary Soaking)> Drying

As technologies began to develop and water resources and facilities were established and applied,

Concentrated people began the water washing process.

In Central America, where water resources are abundant, washing is also almost always used.

Washing flavor: acid obvious, clean flavor, bright

Water washing process:

The first one: the channel to pick beans

Coffee berries flow through the canal (much like the floating river in Mara Bay ~)

This sift light beans, leaves, worm-eaten beans, can also sift heavy stones…and so on.

Second: De-Pulp

Third pass: removal of pulp in fermentation tank (fermentation)

Fourth step: cleaning

Step 5: drying (sun-dry or dry machine)

Currently found in some boutique estates in Guatemala,

In the washing process, after the coffee beans are washed, if they are soaked in the sink again (at least 12 to 24 hours) and then dried, the quality and flavor of the coffee produced will be greatly improved. Therefore, this process has gradually been used, called "secondary soaking".

- Honey Process

Process: Bean picking> Peeling (removing part of peel and pulp)> Dry fermentation>

In order to combine the cleanliness of washing with the sweetness of sunlight, a process called "honey treatment" was created.

After the coffee berries have been peeled (if part of the exocarp and pulp has been removed), they are placed in an off-the-ground shed (or African shed, as some call it) to wait for the peel to ferment. Sometimes it is covered with a masking canvas or gauze to avoid excessive exposure of the beans during long-term fermentation.

Through honey treatment of beans, can be said to combine the characteristics of sunlight and washing,

The flavor is cleaner than sun beans, and the beans are more symmetrical, but still show the bright acidity of coffee.

Duo added: Even if it is honey treatment, the treatment process varies from place to place. Heavy Honey, Red Honey, Light Honey, Yellow Honey... The flavor and the difficulty of the production process are also different!
