An Alternative Way to Reduce Caffeine: The Decaffeination Principle and Controversy of Indonesian Charcoal Coffee Kopi Joss

The modern coffee industry has developed various artificial decaffeination processes, including solvent extraction, supercritical carbon dioxide, and the Swiss Water Process. But in an era of technological scarcity, Indonesians had already found an unexpected way to reduce the caffeine in coffee—by plunging red-hot tamarind wood charcoal into brewed coffee. This is Kopi Joss. This street drink was not originally intended for decaffeination, but was believed to relieve stomach discomfort and ward off cold. Research by Ahmad Fauzan, a chemistry student at Yogyakarta State University, found that tamarind wood charcoal has an iodine absorption rate of 83%, which can reduce the caffeine in black coffee from 68.78 mg/100 ml to 55.13 mg/100 ml, with optimal adsorption occurring at 40 minutes. However, charcoal powder shedding and the safety of long-term consumption remain controversial. Front Street Coffee takes you through the science and tradition behind this cup of "hardcore coffee."

Arabica Caffeine Content Explained: Effects, Health Impact, and a Science-Based Guide to Drinking

Caffeine is a much-discussed active component of coffee.
