An In-depth Look at the ASD (Anaerobic Slow Dry) Processing Method

ASD stands for Anaerobic Slow Dry, a processing technique that combines anaerobic fermentation with slow drying. In this method, the coffee cherries are not depulped but instead placed whole into a sealed fermentation tank. They undergo anaerobic fermentation for up to 120 hours (five days) in a controlled temperature and oxygen environment, which helps enhance the richness and complexity of the flavors. After fermentation, the parchment-covered beans are moved to raised beds for a slow sun drying process of at least five weeks, ensuring a stable moisture reduction while preserving the rich aromas brought by fermentation.

This processing method demands extremely precise environmental control, but precisely because of this, it can impart complex and distinctive flavor profiles to the beans. It is reported that as early as 2019, Elida Estate won the BOP competition with an ASD-processed Geisha and achieved a record-breaking auction price of over $1,000 per pound, showcasing the potential and market recognition of this technique.
