The chemical molecules will decompose the caffeine, and then the caffeine will be evaporated by heating. The final liquid is reintroduced into the coffee beans to reabsorb coffee oils and aromas. This method is quite popular in Europe and also has the names of European law, dichloromethane method, European steps, and so on.

Direct Solvent

This method will steam the coffee beans for about 30 minutes to open the pores of the coffee beans and then add a solvent to rinse them together, usually using dichloromethane or ethyl acetate. After about ten hours, the caffeine can be removed. These solvents are then discarded, and the coffee beans are re-steamed to remove any residual chemicals. This method usually uses ethyl acetate, also known as the natural decaffeination method or the ethyl acetate method.

Carbon Dioxide High-Pressure Extraction

In this method, coffee beans steeping in water are placed in stainless steel barrels, the released carbon dioxide is turned into a liquid under high pressure, and the caffeine is extracted. The carbon dioxide liquid is then returned to room temperature and turned back to gas.
