Professional coffee knowledge exchange more coffee bean information please follow the coffee workshop (Wechat official account cafe_style)

Arabica beans, originally from the Ethiopian plateau, have accounted for 3/4 of global coffee production after years of breeding and improvement, while only about 10% of these Arabica beans can be certified as premium coffee beans (Specialty Coffee). These Arabica beans have a balanced flavor and aroma. The three well-known coffee beans: Kona in Hawaii, Blue Mountains in Jamaica and Mocha in Yemen, belong to this kind of Arabica beans.

The shelf life of coffee is very short. For more information, please see the overview of boutique (top) coffee. In general, what can be seen in the store is to pour the deep-baked beans directly into an open plastic container on a bean grinder or coffee maker. So, in fact, there is no way to tell which cup of coffee delivered to the hand is how long the coffee beans have been brewed?

The annual demand of chain cafes is huge, and it is an impossible task to spend a lot of money on high-grade Arabica raw beans under the premise of business (we must ensure shareholders' profits).

Independent cafes or self-baked cafes have sprung up in recent years, so be careful to choose those who really know and care about the quality of coffee to enjoy high-quality Arabica coffee.

Washing type

The harvested coffee fruit is put into a flowing trough, after the defective fruit floating on the water surface is removed (figure 1), the fruit is picked up and peeled by a peeling machine (figure 2), and the peeled fruit is put into the tank to screen out the inferior fruit floating on the water. The peeled coffee beans will be attached to mucus, so soak and ferment overnight to make the mucus decompose in water. Then scrub with clean water for several times until the pulp is not sticky (figure 3), then dry the pulp for several days (figure 4), and then use a film remover to remove the dried film from the coffee beans.

Sunburn type
