What is Anaerobic Fermentation in Coffee?

Introduction

Coffee is one of the most popular beverages around the world, with millions of people consuming it every day. The taste and aroma of coffee depend on various factors, including the way it's grown, harvested, processed, and roasted. One of the lesser-known processing techniques in coffee is anaerobic fermentation, which is used by some coffee producers to create unique flavor profiles.

What is Anaerobic Fermentation?

Anaerobic fermentation is a process in which bacteria and yeast break down the natural sugars present in the coffee cherries without the presence of oxygen. This process is carried out in tanks or containers, which are sealed to prevent oxygen from entering. During the fermentation process, the bacteria and yeast produce different organic acids, which give coffee its characteristic taste.

Bridging the Gap in Colombia

Cafe Ocampos, a coffee producer in Colombia, uses anaerobic fermentation to create its unique flavor profile. The coffee beans are hand-harvested and subjected to a rigorous selection process to ensure only the ripest cherries are chosen. After selection, the beans are fermented for 12-18 hours, depending on the weather conditions, in tanks to develop their flavor.

Mechanically Drying Coffee

Once the fermentation process is complete, the coffee beans are mechanically dried at low temperatures to simulate day and night drying conditions. This process stabilizes the water activity within the beans, ensuring even roasting and a longer shelf life. After 36 hours at 40 degrees Celsius, the coffee beans stabilize for 2 weeks to 1 month to allow the flavors to fully develop.

Cafe Ocampos' milling process is carried out with utmost care and attention to ensure each bean is processed to perfection, guided by preselected quality standards. The result is a coffee with a complex and rich flavor profile, perfect for coffee enthusiasts who crave something special.

Conclusion

In conclusion, anaerobic fermentation is a unique processing technique used by some coffee producers to create distinct and exquisite coffee flavors. Cafe Ocampos, with its commitment to quality and excellence, is a perfect example of how this technique can be used to produce exceptional coffee.
