Decaf

Chemical Process – Methylene Chloride (Also called European Process or KVW)
Coffee cuppers will usually pick decafs processed with methylene chloride as the best in cup quality. Beans are soaked in near-boiling water, extracting the flavor oils and caffeine from the coffee. The water is separated into a tank where it is treated with methylene chloride. It bonds to the caffeine and is then easily removed from the flavor oils. The beans are reintroduced, absorbing their long lost flavor.
