Qianjie-Coffee processing method introduction

The harvest time of coffee fruit produced in different countries and regions is different, usually when the coffee fruit is bright red when the flower thickness is about 7 to 8 months, which is called "coffee cherry" (coffee cherries). The definition of treatment refers to the removal of the exocarp, endocarp, silver skin of coffee cherry. Wait for five parts, and finally get the coffee beans. Generally speaking, there are five ways to treat coffee cherries into raw coffee beans, which are:

Washing method (Wet process/Washed method):

Washed beans account for about 70% of all coffee. The technology invented by the Dutch in the 18th century is suitable for rainy areas. The coffee treated by water washing has a bright and clean taste, strong sour taste, weak consistency and less impurities.

First, add a lot of water to the coffee cherries, rinse away the unfinished fruits and impurities floating on the surface, select beans, and then use a peeling machine to remove the peel and pulp. Then put it into the fermentation tank to ferment for 18 hours for 36 hours, make the fermentation bacteria dissolve the pectin on the surface of coffee cherries, wash it with clean water, dry it for 1-3 weeks, then dry it with a machine, and use a sheller to remove endocarp, peel, seed shell and silver film, which is quite cumbersome.

Washed beans are bluish green in color and beautiful in appearance. Coffee from Guatemala, Colombia, Blue Mountains, Kona, Kenya, Java and Panama are all washed beans.

Sun exposure (Dry process/Natural method):

Arabs have treated coffee in this way since the beginning of the habit of drinking coffee, that is, more than a thousand years ago. Sun-cured coffee has a soft sour taste and a uniform bitter taste, and has a high consistency.

The method of treatment is that the coffee cherry is harvested and exposed to the sun for 3 to 4 weeks, and it is turned evenly several times a day, so that the coffee cherry is evenly heated, the core and skin of the coffee will be separated after drying, and then the pulp and peel will be removed by a sheller. And so on, the screening is completed.

Sun-cured beans have a better flavor, but are prone to defects in appearance. Coffee beans from Yemenmoka, Esopiaha, Brazil and Sulawesi, Indonesia are often treated with this method.

Honey treatment (Honey Process):

Honey treatment is a method of raw bean treatment, called Honey Process or Miel Process, called Honey Coffee, Costa Rica, Panama.

Honey treatment is a kind of treatment between sun treatment and water washing. It keeps the coffee clean, and although the brightness decreases, it increases the sweetness and caramel flavor of the coffee. The appearance of honey-treated beans has a distinct sticky layer. But the honey treatment method is very dependent on the local climate, the weather must be dry and adequate sunshine, otherwise it is not suitable for honey treatment.

Knowledge: the quality of coffee can be changed according to altitude, latitude and soil chemical composition. Growing coffee outside the right range of factors will greatly change the final quality of coffee.
