Treatment is not only a necessary condition for making a coffee bean, but also a crucial step, which guides the direction of coffee flavor.

What is coffee bean treatment? For example, common washing, sun and honey treatment and so on. These treatments refer to the raw bean treatment, which is the process of getting the raw bean part of the coffee fruit, scraping off the pulp, pericarp, pectin layer and so on. The post-processing of coffee after harvest, knowing how to handle it can help you choose your favorite flavor.

Wash / collect / flotation / rinse

Coffee fruits are sent to be processed immediately after picking, usually within 6 to 12 hours after picking. The coffee fruit is first weighed and then soaked in water in order to select the fruit that floats because of its poor quality.

Peeling / beating

The coffee fruit is then sent to a beater for peeling, a step to remove the skin and pulp from the coffee fruit.

Fermentation / degumming

Coffee fruits without pulp and peel are sent to fermentation tanks or buckets for 18 to 36 hours, where enzymes decompose the mucus / pectin in the coffee fruit.

Wash away

The degummed coffee fruit will be cleaned by adding an appropriate amount of water to the pool. During the cleaning process, the pectin decomposition on the surface of the coffee bean will be removed by stirring, leaving coffee sheepskin, silver skin and raw beans.

Drying

Washed coffee beans are sorted to remove defective coffee beans. Then it will be sent to the drying place (tarpaulin, cement floor, high bed, etc.) for drying treatment. Drying treatment will be based on the environment and climate and other factors to determine the length of time, usually ranging from 5 to 14 days. At this time, the moisture content of coffee beans will drop from 55%.

To 11%.

Warehousing

Dried coffee beans are called shelled beans-raw coffee beans with sheep skin. The shell beans will be sent to the warehouse for preservation and will be shelled before export.

In the traditional treatment, the stability of water washing treatment is the highest, the treated coffee is sour, while the sun-treated coffee is the sweetest.

Compared with the sun treatment, the complexity of the sun treatment is not as good as that of the sun. Sun-cured coffee has a heavier berry flavor, is more complex, and is easier to be sweeter than washed coffee. Will produce more berry tonality, but also more complex.
