After harvesting the raw beans of Yunnan coffee, the berries are either sent directly to the pulp collector (if the harvest is done well) or concentrated in a siphon jar filled with water. The berries are washed and separated in this jar. The stone sank to the bottom of the jar and was picked up by hand when the jar was emptied. Lighter berries float on the water and are removed with a hedge along with leaves and twigs. The berries suspended in the water are then recovered by a siphon and transported to the pulp collector.
The purpose of removing the pulp is to separate the pulp from the seed coat of coffee beans. The pulp is removed by squeezing the berries. Because ripe berries contain a lot of moisture, peeled coffee beans can easily pop out when the berries are squeezed.
The next step is to remove the mucus, which aims to remove the residue of the mesocarp that clings to the seed coat after the pulp has been removed (see the illustration of the various parts of the coffee berry). Because the mucus is insoluble in water and tightly attached to the seed coat, it cannot be removed by simple cleaning, so it either needs to be cleaned after fermentation or can be removed by strong friction in an equipment called a mucus remover.
In Yunnan, this process is mainly accomplished by natural fermentation. The term fermentation is not 100% accurate because there is no biochemical reaction inside the coffee beans. It is more appropriate to call this process the use of biochemical reaction or hydrolysis to remove mucus. This reaction is caused by natural enzymes in coffee berries.
The fermentation time varies from 6 hours to 72 hours, depending on the temperature, the amount of mucus and the concentration of digestive enzymes. Put the coffee in a fermentor until the mucus is completely decomposed and the beans can be washed.
The key to ensuring the quality of coffee is to stop fermentation at the right time, because excessive fermentation can lead to the emergence of so-called smelly coffee beans. If the fermentation is insufficient or too slow, butyric acid or propionic acid will be produced, both of which will adversely affect the quality of coffee.
The fermented coffee with skin needs to be cleaned immediately after the completion of the fermentation process to terminate the process. However, after removing the mucus and before cleaning, it may be necessary to soak the coffee with skin in clean water for 12 to 24 hours to reduce the bitter taste of the coffee drink.
