Many of … Our decaf process uses carbon dioxide, a completely natural resource, found in the air we breathe. With GCE in hand, the decaffeination of green beans that will go to roast can begin! In the 1980s the Swiss firm Coffex S.A. developed a commercially viable decaffeination process using water only — no solvents whatsoever. One such process, the Swiss water process (invented in Switzerland), is based solely on water and carbon filtering. Coffee beans are soaked in water. Here is how the process works: The beans are left to soak in water, which allows them to grow in size, making the decaffeination process easier. This method uses two natural elements, pure water and carbon dioxide. The Ethyl Acetate decaf method exposes the green beans to water and steam in order to expand the cells of the bean before washing them with an Ethyl Acetate solution, which attracts and removes the caffeine. As in the indirect solvent or solvent/water process described earlier, the various chemical constituents of the green coffee, including the caffeine, are first removed by soaking the beans in very hot water. First, a fresh batch of green beans is immersed in a tank full of GCE. Tea leaves are soaked in a carbon dioxide solution to release caffeine. This is the type of natural decaffeination that you will find in health food store products, and it is always more expensive, because it is a considerably more complex process.

The molecule rich GCE and green beans reach chemical equilibrium by rebalancing the caffeine content. The water lures the caffeine from the bean and into the water. The GCE water is then passed through a caffeine-capturing filter and the process is repeated until the beans are 99.9% caffeine-free. While there are four primary methods of decaffeination, we are focusing only on the two non-solvent, natural decaffeination processes used by, and Mills Coffee: Swiss Water Process (SWP) and Carbon Dioxide (CO. ) Processes — the latter being the process used on of 95%+ of our decaf offerings.

Like all other solvent-based processes, natural decaffeination works by first steaming the coffee beans so that they are receptive to the solvent. During the decaffeination process, the caffeine chemical is extracted from the bean using either chemicals or water and / or pressure. Therefore, we are not adding any synthetic chemical substance. What this process requires is liquid CO2, coffee beans, and stainless steel extraction vessels.
