Most decaffeinated coffee is made using a chemical process first used in Europe.

This process involves soaking the beans in water and then "washing" them in methylene chloride to absorb the caffeine from the bean. After this, the beans are rinsed clean of the chemicals and dried.

The advantage of this method is that it provides decaf coffee with more flavor than the swiss water process.

This method of decaffeination is rumored to create carcinogenic beans.
