What makes solvent-based decaffeination different from other methods?

Solvent-based decaffeination stands out due to its use of specific chemicals in the process, such as methylene chloride or ethyl acetate. These solvents help to selectively remove caffeine from coffee beans while aiming to maintain as much of the original flavor profile as possible. The use of these chemicals is a defining characteristic of this method, distinguishing it from alternatives like water-based or carbon dioxide decaffeination processes, which do not rely on chemical solvents in the same way.

Other methods may emphasize being chemical-free, focusing on natural processes or physical means to decaffeinate. While solvent-based decaffeination does aim to preserve flavor, it is the utilization of these chemicals that primarily defines and distinguishes it. Moreover, the statement regarding it being done only locally is unfounded as solvent-based decaffeination is practiced globally, making it a common method across various regions.
