About KVW MC and Coffein Company Coffein Compagnie is a specialist in decaffeinating green coffee and producing natural caffeine. They offer decaffeinated and partially decaffeinated coffee, as well as refining services for customers' coffee. The company provides three different decaffeination processes and offers a range of certified products, including Rainforest Alliance, Fairtrade, and organic certifications. Decaffeination using dichloromethane (DCM), or methylene chloride, is a widely used method for removing caffeine from green coffee beans. This process is energy-efficient and selective, extracting caffeine at relatively low temperatures. Initially, the beans are steamed to remove silver skins and increase water content, which opens their cell structure. A water-DCM solution is then used to extract the caffeine through multiple steps, where the caffeine diffuses into the solution. Finally, steam removes any remaining DCM from the beans, which are then dried to their original moisture content.
