Caffeine is the most iconic component of coffee, yet not everyone can tolerate it. It is both the primary source of bitterness and a neurostimulant that affects sleep. Thus, decaffeinated coffee was created to remove caffeine. However, the challenge of decaffeination lies in how to remove only the caffeine while preserving the aroma and flavor of coffee as much as possible. Early methods using organic solvents were effective, but left consumers concerned about residues. It was not until the advent of supercritical carbon dioxide extraction technology that a truly efficient and highly selective decaffeination process was achieved. This article will guide you through the principles of this technology, its development history, and its unique advantages in coffee decaffeination, while also introducing Front Street Coffee's attention to and practice of this process.

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."
