- Swiss water process. This method is an organic way of decaffeinating coffee. It utilizes osmosis to extract caffeine and have a 99.9% decaffeinated result.
- Solvent-based process. This method uses the combination of methylene chloride, ethyl acetate and water to make solvent used to extract the caffeine.
- Carbon dioxide process. From the name itself, this method uses carbon dioxide, a compound found in coffee as a gas, removing the caffeine and leaving other flavor compounds intact.
