Solarization:

Sun treatment will first identify sunken beans in the sink, that is, ripe or half-ripe beans are spread in the drying farm for natural drying. The specific time depends on the local climatic conditions, which usually takes two to four weeks. When the moisture of the coffee bean is reduced to 12%, then use a sheller to grind off the hard pulp and silver skin.

Washing method (washed)

1. Choose beans:

Put the harvested fruit in a water tank and soak for about 24 hours. At this time, ripe fruit will sink, while immature and overripe fruit will float up and can be removed.

2. Remove the pulp:

Use a machine to remove the peel and pulp, leaving only coffee beans wrapped in endocarp. At this time, there is a layer of mucous membrane on the outside of the beans, and the process of washing is to wash this layer of mucous membrane.

3, hair alcohol:

The adhesion of the mucous membrane is very strong and is not easy to remove. It must be placed in the slot for about 18-36 hours to make it alcohol and decompose the mucous membrane. There are two methods of fermentation, namely wet hair alcohol and dry hair alcohol, as the name implies, the former adds water, the latter does not add water. In the process of producing alcohol, the seeds and internal pulp will produce special changes, which is one of the steps that most affect the flavor of coffee. Some farms add hot water or alkanolins to speed up the production of alcohol, which has a negative impact on quality and is not popular with selected coffee lovers.

4, washing:

Farms that use the washing method must build washing ponds and be able to introduce an endless supply of running water. During the treatment, the finished beans are put into the pool and passed back and forth, using the friction of beans and the power of running water to wash the coffee beans until smooth and clean.

5, dry:

After washing, at this time, the coffee beans are still wrapped in the pericarp with a moisture content of 50%. They must be dried to reduce the moisture content to 12%, otherwise they will continue to be mellow, moldy and rotten. The better treatment is to use sunlight to dry, although it will take 1-3 weeks, but the flavor is very good and very popular. In addition, machine drying is used in some places, which greatly shortens the processing time and makes the flavor not as good as that of sun-dried coffee.

Honey treatment method

The so-called honey treatment (honeyProcess) is said to mean the process of making raw beans by sun-drying with mucous membranes. After the outer pulp of the coffee bean is removed, there will be a layer of sticky jelly. The traditional method of washing is to wash it off with clean water, but because of the limitation of water resources in some high-altitude areas, there is this way of direct drying.

The honey treatment process is vulnerable to pollution and mildew, so it needs to be closely watched throughout the process, constantly turning, and speeding up drying, so as to avoid bad fermentation flavor. Its advantage is that it can best preserve the original sweet flavor of coffee ripe fruit, making the coffee show elegant black sugar flavor and drupe flavor, while the berry flavor also supports the basic aroma of red wine, which is considered to be a very elegant product. The popularity of honey-treated coffee beans is largely due to their sweet and thick characteristics, which are very suitable for Espresso production in cafes. In recent years, more and more coffee beans are called "honeyProcess", and they have also become a favorite material for international coffee contestants.
