How does decaffeinated coffee work? How is it made?

Decaffeinated coffee is made by removing most of the caffeine from coffee beans while trying to preserve their flavor.

CO₂ Process: In this method, carbon dioxide (CO₂) under high pressure is used to extract caffeine from the beans. The CO₂ acts as a solvent, binding to the caffeine molecules and drawing them out of the beans. It's then passed through a filter to remove the caffeine before the beans are dried and roasted.
