Coffein Compagnie - Ethyl Acetate (EA) Decaffeination (Sugarcane Process)

Ethyl acetate is a preferred choice for decaffeination due to its ability to selectively target and remove caffeine from green coffee beans in a precise and gentle way.

The process begins with steaming the green beans to eliminate the silverskin and raise their moisture content, which opens up their cellular structure. A water and ethyl acetate solution is then used in multiple steps to effectively extract the caffeine. To finish, the beans are steamed again to eliminate any traces of ethyl acetate before being dried back to their original moisture level.

Ethyl acetate is naturally found in sugar cane, coffee, and fruits like musk, strawberries, and bananas, although it can also be synthetically produced.

Dolor sit ameCR3-Kaffeeveredelung M. Hermsen - CO2 Subcritical Decaffeination

Developed by CR3 in the late 1980s, this innovative method uses natural carbon dioxide under subcritical conditions—meaning low temperature and pressure—to carefully remove caffeine while preserving the full flavor potential of the green coffee. The process is fully certified organic.

Unroasted coffee is first moistened and placed into a chamber filled with pressurized liquid carbon dioxide. The CO2 flows through the coffee, targeting and removing caffeine. Once the desired level of decaffeination is reached, the circulation stops, and the coffee is gently dried back to its original moisture content. The caffeine is separated from the CO2, allowing both to be reused efficiently.


Swiss Water® Process

The Swiss Water® Process carefully removes caffeine using just water, temperature, and time, while retaining the coffee’s full flavor profile.

Green coffee beans, rehydrated to the ideal moisture level for decaffeination, are immersed in a Green Coffee Extract (GCE). This extract is a solution of fresh water containing all the coffee's soluble components—except caffeine. The GCE circulates around the beans, initiating a diffusion process that selectively removes caffeine, the only compound disrupting balance, without affecting the coffee's flavor. This process continues for 8-10 hours until the caffeine content drops to no more than 0.1%. The caffeine is then extracted from the GCE using a proprietary carbon filtration system, allowing the GCE to be reused.
