What Is Robusta Coffee Fermentation Process?

Remember those early high school lessons: fermentation is a chemical reaction. The combination of yeast, bacteria and other microorganisms makes it easier for one substance to break down into other substances. Usually, the substances that are broken down are sugars. When this happens, they tend to give off heat. In addition, different enzymes can catalyze this event.

Or, to put it more simply, the fermentation of Robusta coffee is a natural change that occurs when you put sugar and water together – and in well-picked coffee, both elements are present. This element. And so, as soon as the ripe coffee berries are harvested (or even while they are still on the tree), the fermentation of Robusta coffee will begin.

The question is, does this Robusta fermentation improve the taste of the coffee or ruin it? Together we will find the answer.

Robusta Coffee Fermentation Process?

Fermenting Robusta coffee is an integral part of the post-harvest processing of coffee. It can happen in one of two ways:

  • Aerobic: This is what happens in the presence of oxygen. The technique of this Robusta coffee fermenter is simple: place the recently harvested ripe cherries in a barrel or container and let the microorganisms work. Monitor time and temperature to help you control and analyze it.
  • Anaerobic (anaerobic): In this case, the coffee cherries are placed in a tank (before or after grinding) and covered in water, allowing different microorganisms to work.

The anaerobic (anaerobic) fermentation of Robusta coffee in water will be more homogeneous and easier to monitor, whereas the aerobic environment is heterogeneous and more complex.

Fermenting Robusta coffee is a chemical process in which complex molecules are broken down into simpler molecules, creating liquid and gaseous products (volatile compounds). Coffee cherries are processed using one of three methods immediately after harvest to allow spontaneous fermentation of Robusta coffee or intentional fermentation of Robusta coffee.
