This method is a chemical-free alternative to decaffeination and is favored by those seeking a more natural option.
How It Works:
The Swiss Water Process relies on a carbon-filtering technique. The coffee beans are soaked in hot water to dissolve caffeine, but this water also extracts other flavor components. The solution is then passed through activated charcoal, which captures the caffeine. This process maintains the beans’ flavor profile without introducing any chemicals.
Benefits of the Swiss Water Process:
One significant advantage of this method is that it is 100% chemical-free, making it the preferred choice for health-conscious consumers. Additionally, it can preserve the beans’ flavor better than other methods.
3. CO2 (Carbon Dioxide) Method
Another method that has gained popularity is the use of liquid carbon dioxide to decaffeinate coffee.
How It Works:
In this process, the green coffee beans are placed in a stainless-steel vessel, and CO2 is pressurized to a supercritical state. When used in this state, CO2 acts like a solvent, extracting caffeine while minimizing damage to the flavor compounds in the beans.
Advantages of the CO2 Method:
This method is generally regarded as one of the safest decaffeination processes. It does not leave any chemical residues and is environmentally friendly.
