FrontStreet Coffee - Introduction to Anaerobic Coffee Processing

Processing Methods

Currently, the most common traditional coffee processing methods include: fully washed processing (double washed and semi-washed are also long-established processing methods); fully natural processing; honey processing (originating from Brazil where it's called pulped natural, popularized in Costa Rica and promoted globally); and wet-hulled processing (popular in Indonesia and parts of Southeast Asia).

The impact of processing methods on coffee flavor (both positive and negative) is enormous. Therefore, coffee producers have conducted research on processing and introduced various experimental processing methods different from traditional approaches. The core principle is to process coffee with innovative flavors according to the special conditions of origin and coffee varieties (without changing the coffee varieties themselves). Experimental processing methods stem from the specialty consumer market's demand for unique flavors, with the goal of increasing coffee's added value and creating more profit.

"Processing is one of the important factors affecting flavor. Good processing by producers helps quickly create high-scoring coffee with special flavors (relative to coffee variety improvement and breeding). Consumers can easily experience premium flavor profiles and interesting tones they haven't encountered before. The key controversy regarding experimental processing methods lies in balancing artificial traces and natural flavors."

Anaerobic Processing Method

A Special Processing Method Trending Worldwide

Simple Introduction to Anaerobic Processing

Select fully mature coffee cherries with sugar content reaching a certain level and sufficient quality. Place them in a completely sealed, monitorable container filled with carbon dioxide for fermentation. During the fermentation process, strictly control temperature and pH value changes. When the sugars in the pectin and mucilage are just completely consumed, immediately open the container to stop fermentation and quickly dry under sunlight to avoid over-fermentation.

Coffee beans produced using this processing method have fuller body, bright wine-like aroma, low acidity, and better sweetness.

Knowledge point: Coffee roasting is the process that triggers Maillard reactions and caramelization reactions inside green beans, producing more wonderful flavors.
