Coffee beans aren’t grown caffeine free. Many coffee drinkers are forced to switch to decaf in order to keep their health in tact, or get to bed early. It’s not likely they sit around researching the decaffeination process.
For those coffee drinkers that are interested the process works something like this: Green coffee beans are contacted with carbon dioxide at temperatures of 90-100 degrees Celsius. The combination of heat and carbon dioxide removes up to 97 percent of the caffeine.
Another decaffeination method is solvent extraction using oil or ethyl acetate as a solvent. The beans are coated with the solvent, and the solvent absorbs the caffeine. Upon removal from the solvent steam is used to clean the solvent from the beans.
