Coffee Processing Glossary

Understanding technical terms and industry jargon can be a daunting task, especially when it comes to a complex and specialised topic like coffee processing. Coffee processing is a constantly evolving part of the coffee suply chain, with new methods and adaptions of established ones, seemingly appearing every day.

That's why we have created this Coffee Processing Glossary, which includes descriptions of the processing methods we've encountered to date. We'll keep this updated as we discover new methods through our sourcing and partners so check back whenever you encounter something new.

Whether you're new to the world of coffee or an experienced roaster or barista, we hope this glossary will help you navigate the terminology and understand the nuances of different coffee processing techniques.

Processing Methods

Anaerobic Process

Anaerobic coffee fermentation is a processing method that involves fermenting coffee beans in the absence of oxygen. This is typically achieved by placing the coffee beans in a sealed container or tank.

The process starts with the depulping of the coffee cherries, after which the beans are placed in a sealed container with a small amount of water to create an oxygen-free environment. The container may also be flushed with nitrogen gas to ensure that no oxygen is present.

During the anaerobic fermentation process, the coffee beans are broken down by bacteria and yeast that thrive in oxygen-free environments. This leads to unique and complex flavors in the coffee, as the bacteria and yeast produce various organic acids and other compounds that affect the flavor profile.

The duration of the fermentation process can vary depending on the desired flavor profile, but it typically ranges from 24 to 72 hours. Once the fermentation process is complete, the coffee cherry can then be processed through traditonal methods.
