Choose fresh coffee beans. When buying, pay attention to whether the color of the beans and the size of the particles are the same. Good coffee beans are shiny and have a strong aroma without being mixed with peculiar smell. No matter what kind of coffee beans, freshness is an important factor affecting the quality. When shopping, grab one or two coffee beans in your mouth and chew them with a crisp sound (indicating that the coffee is not damp) and the fragrance of the teeth and cheeks is the top grade, but it is best to squeeze it with your hands to feel whether it is solid, rather than buying crispy coffee. If the coffee bean has lost its fragrance or smells stale, it means that the coffee bean is no longer fresh and is not suitable for purchase.

Freshly fried coffee beans are not suitable for drinking immediately and should be stored for a week in order to completely release the gas in the beans.

After the fruit is harvested, the outer skin, pulp, endocarp and silver skin should be removed before shipping. There are two kinds of methods: drying (also known as natural or non-washing) and washing. The drying method is relatively simple.

First of all, spread the freshly harvested fruit on the exposure field for a week or two until the fruit crackles and dries naturally.

After that, the dried pulp, endocarp and silver peel are removed by a sheller.

Coffee beans refined in this way are slightly sour and slightly bitter. Almost all coffee beans produced in Brazil, Ethiopia, Yemen and other places are obtained in this way. The disadvantage of this method is that it is easily affected by weather and is easy to be mixed with defective beans and other impurities. Therefore, it must be carefully screened.

Another way is to wash the fruit, in which the fruit to be harvested is put into a flowing trough. After the floating fruit is removed, the skin and flesh are removed by a pulp remover. Then put it in the sink to remove the emerging pulp. After that, move into the fermentation tank, soak for half a day to a day, and then dissolve the gum on the surface of the fermented coffee beans. After washing with water, drying it for a few days, drying it with a machine, and finally using a sheller to remove the endocarp to become a commercial raw coffee bean.

Water-washed coffee beans have more beautiful color and less impurities. Colombia, Mexico, Guatemala and other countries adopt this method for about 70% of their output.

Sometimes in the fermentation process, if not handled properly, it may give off fermentation odor and its unique sour taste, but if handled properly, all kinds of beans can give off their unique coffee aroma.

In order to be delivered completely to the destination, raw coffee beans are packed in sacks and placed in special containers for long-distance merchant shipping trips.
