Processing
Swiss Water Process
Chemical-free decaffeination using only water. Removes 99.9% of caffeine while preserving origin character. The gold standard for specialty decaf.
Definition
How Swiss Water works
Swiss Water Process uses Green Coffee Extract (GCE)--water saturated with coffee's soluble compounds minus caffeine. When green beans soak in this water, only caffeine migrates out (because GCE already contains everything else).
The process is repeated until 99.9% of caffeine is removed. No chemicals ever touch the beans. The caffeine is then removed from the water using activated charcoal, and the GCE is reused.
