Decaff coffee ☕ Supercritical CO2 Process

The Supercritical CO2 process takes green coffee beans and steams them. Then they are added to a high pressure vessel where a mixture of water and liquid CO2 is circulated at 65 ºC degrees (150°F). Caffeine dissolves into the CO2 while compounds contributing to the coffee flavor is largely insoluble in CO2 and remains in the bean. In a separate vessel, caffeine is scrubbed from the CO2 with additional water. The CO2 is then recirculated to the pressure vessel. #coffee #relax
