Overview¶
Coffee bean processing is the transformation of the harvested coffee cherry into a stable, dried green bean ready for export and roasting. The processing method chosen after harvest is one of the most significant determinants of a coffee's flavour profile, influencing body, acidity, sweetness, and aromatic character. The four principal processing categories are washed (wet), natural (dry), honey (pulped natural), and wet-hulled (Giling Basah), with a growing range of experimental methods — including anaerobic fermentation, carbonic maceration, and yeast-inoculated fermentation — gaining traction in the specialty sector. Each method manages the removal of the coffee cherry's fruit layers at a different stage and with different degrees of fermentation contact.
Processing Method Overview¶
| Method | Key characteristic | Cup profile tendency |
|---|---|---|
| Washed | Fruit removed before drying; fermentation in water | Clean, bright, high acidity, clear origin expression |
| Natural | Whole cherry dried with fruit intact | Heavy body, fruit-forward, complex, lower acidity |
| Honey | Skin removed; some mucilage remains during drying | Sweet, rounded, intermediate between washed and natural |
| Wet-hulled (Giling Basah) | Parchment removed at high moisture; Indonesia-specific | Low acidity, heavy body, earthy/herbal character |
| Experimental | Controlled fermentation environments (anaerobic, COâ‚‚) | Variable; typically complex, fruit-intensive profiles |
Key Facts¶
- Processing converts the coffee cherry (fruit) into dried green bean (seed) through managed removal of fruit layers and controlled drying
- The method fundamentally shapes cup character — washed coffees express origin character cleanly; natural coffees amplify fruit and body
- Proper drying to 10–12% moisture content is critical for green bean stability and storage
- Experimental processing methods have proliferated in the specialty sector since approximately 2015
