Introduction to the process of Qianjie-semi-washing treatment
Semi-washing treatment (Semi washed) can be said to be the combination of sun-drying and water-washing. The idea is to use less water than water washing to produce coffee with a cleaner flavor and a thicker taste than the sun washing method, which is popular in Indonesia, Manning and other places, and Brazil has also begun to use semi-water washing in recent years.
Step 1: filter
As with other treatments, coffee cherries need to be screened first. If you put the picked coffee cherries in the pool, the ripe fruit will precipitate to the bottom of the pool, while the unripe fruit will float on the surface. Coffee farmers need to screen out the immature fruit first.
Step 2: remove the peel and pulp
The procedure is the same as the washing method, using a special machine to remove the peel and pulp, leaving only the coffee beans wrapped in the endocarp, but at this time, there is still a small layer of colloid on it.
Step 3: remove pectin
Use a pectin scraping machine (Demucilager) to remove the attached pectin, which uses only a small amount of water compared to the washing method.
Step 4: air drying
Take out the coffee beans with a smooth surface and dry them outdoors until the water content is reduced to 12%.
Flavor characteristics
Semi-washed coffee not only has the thick flavor and sweetness of sun beans, but also has the clean, soft but not insipid taste of washed beans.
Knowledge: although coffee beans are called beans, they are actually the seeds of the fruits of Rubiaceae (coffee trees).
