Anaerobic fermentation processing is a green bean processing technology that has attracted much attention in the coffee industry in recent years. Since Sasa Sestic, the 2015 WBC champion, brought it to the forefront, it has quickly swept through the specialty coffee world. Inspired by red wine-making techniques, this processing method injects carbon dioxide into a sealed container to expel oxygen, creating an oxygen-free environment that allows precise control of the fermentation process, giving coffee beans higher sweetness and more unique flavor layers. As processing technologies continue to evolve, experimental methods such as anaerobic natural, anaerobic washed, and double anaerobic have emerged one after another, each presenting distinctly different flavor expressions. This article will systematically sort out the principles and origins of anaerobic fermentation, and analyze one by one the process steps and flavor characteristics of these three common anaerobic processing methods, while also explaining them in conjunction with specific Front Street Coffee bean offerings.
