Fermentation: Since the Neo-Stone Age, humans have used fermentation to produce all kinds of beverages and pickles. Fermentation is a metabolic process that turns sugar into acid, gas, or alcohol. It is often widely used to describe the growth of microorganisms.

Changes in temperature, timing, sugar, and type of bacteria will produce different results during fermentation, so coffee producers are always looking for control over how we ferment (during wet – or semi-wet processing) and looking for better results and understanding of existing processes and environments.
