Decaffeination is achieved by an industrial process in which the beans are exposed to a solvent to leach out the caffeine.

I have a violent allergic reaction to this crap and I am the only person I have ever heard of who does.

Anybody else here who does?

I've heard there are others. You're not alone.

There's also a water process to remove caffine from coffee, if you're really interested in drinking coffee without it.

It is Methlyne Chloride or Dichlromethane that is used to remove the caffine.

Was that a long time ago? They used to use organic, and even chlorinated, solvents to extract the caffeine, but for the last 15-20 years, supercritical CO2 is used, and that leaves nothing of itself behind.

I was taking a course at the time when a classmate, a chemist from General Foods, told me that Coca-Cola and Pepsi were buying every gram of caffeine they could get out of the coffee.
