In recent years, the coffee industry has seen the emergence of a new processing method called “anaerobic.” This technique involves fermenting coffee in a low-oxygen environment, which can produce unique and flavorful coffees. However, it’s important to note that “anaerobic” can refer to various approaches.
The process starts with careful cherry selection, using a floating station to separate out damaged or unripe cherries. Only the highest-quality fruit is used in the next stage. The duration of anaerobic fermentation can vary, but it typically lasts between 48 and 72 hours. The tanks are sealed to prevent oxygen from entering, but gases can escape through valves. The fermentation process is monitored by regularly assessing the liquid content and soluble solids.
After fermentation is complete, the coffee beans are dried using natural methods, which further enhance their flavour profile. The beans are hand-raked to ensure even drying, and both anaerobic and standard naturals undergo a resting period before being prepared for export.
Anaerobic coffee processing is a fascinating example of innovation, tradition, and quality-focused craftsmanship. By exploring and understanding the nuances of processing methods like anaerobic fermentation, coffee lovers can experience a world of diverse and exceptional coffee flavours.
