Flavor description of coffee beans treated with water washing and sun honey grinding scale by taste treatment method

We know that the treatment of raw coffee beans can be roughly divided into three types. The distinction between each method is based on the fact that several layers of matter are removed from the fruit before the coffee is dried. The following is a list of the three major processing methods:

1. Natural sun treatment: retain all substances

two。 Honey treatment: remove the peel and pulp and retain some or all of the mucous membrane (honey)

3. Washing method: the peel, pulp and mucous membrane are removed by washing and fermentation. This method is also known as the complete washing method (Fully Washed). Shampoo is the most common way for most coffee-producing countries in the world to handle Arabica coffee beans. Some areas also use advanced high-pressure washing machines to clean the peel, pulp and mucous membrane of coffee beans, so fermentation is no longer needed. This method of using a high-pressure washing machine to treat coffee beans is called "natural washing (Pulped Natural)".

Brazilian coffee fields are endless and are mostly harvested mechanically in order to meet the economic benefits. When 75% of the coffee fruit in the coffee garden turns red, mechanical harvesting is started, followed by the same pre-washing operation, which is moved into the sink to remove floating beans, sift out the sunken beans, and then use a large pulp screening machine to dig out the pulp and remove the pods covered with pectin. The next stage is separate from the washing method: the sticky pods do not need to be moved into the tank to ferment, but to the outdoor bean drying farm. Because of the dry climate in Brazil, the sticky pectin on the pods will harden in about a day or so. Then use a large number of manpower to turn up and down, so that the pods dry evenly inside and outside, so as not to return to moisture and stink. For about two to three days, with the help of the natural forces of sunlight and dry climate, the pods can achieve a certain degree of dehydration. Then further dry with a dryer, the water content is reduced to 10.5%, and the pods are stored in a special container for about 10 days to further mature, in order to stabilize the quality, remove sheep skins (pods) before export, remove coffee beans, and pack them in stages. 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 getting mellow, the seeds and internal pulp will have special changes, which is one of the steps that most affect the flavor of coffee after washing.
