![]() This is also known as Honey or Pulped Natural coffee. This allows for some measure of fermentation to continue throughout the drying process. Medium Fermentation (Semi-washed)įor this method the cherries have their skins removed during the pulping process but instead of completely removing the mucilage, as in the wet process, the sticky flesh layer is left around the beans. This process allows the farmer to carefully control how much fermentation takes place and results in a more consistent coffee with clean and complex flavors. This leaves the beans covered in just a thin sheath, or parchment, called the endocarp. The beans are then washed thoroughly in fresh water to stop the fermentation process and to remove the last of the pulp. The pulped beans are sorted by size and then thrown into fermentation tanks.Īfter 12 to 48 hours of fermentation in the tank, the naturally occurring enzymes dissolve the layer of mucilage surrounding the beans. It has become the most common way of fermenting coffee. This is the more modern, quicker process but it uses a lot of water. Each process has its own logistical pros and cons and the process can have a significant effect on the taste of the final product. There are three main ways of processing the harvested cherries through the fermentation stage. It’s these acids that will be responsible for adding depth and complexity to the coffee. The fermentation process is where the microbial reaction of bacteria and yeasts break down the sugars in the mucilage to produce acids. After depulping, the beans still have some pulp attached and are ready for the fermentation process. This pulp and skin is usually discarded to be used as compost but some “zero waste” coffee producers use these byproducts to make things like tea from the skins ( 4). Within 24 hours of the cherries being picked, they are put through a depulping machine that removes the skin and most of the pulp. A pulper machine is used to mechanically remove the skin of the coffee cherry.
