The swiss water method sees the beans soaked with water.

How does the swiss water process remove caffeine from coffee. Swiss water makes the gce by soaking the green coffee in water to pull out the caffeine and flavor molecules from this first batch of beans. The water now has only flavor molecules and is what swiss water calls the green coffee extract or gce. Everything that is soluble dissolves and ends up in the water including the caffeine and all the good stuff.

The swiss water process or water only process method of decaffeinating coffee involves first soaking green coffee beans milled but not yet roasted in hot water causing the beans to release their caffeine and solids coffee flavor materials into the water which becomes thoroughly saturated with all of the coffees soluble components except caffeine. The coffee beans are then dried to their originating moisture level and re bagged. About 12 kg of water depending on how many grounds we use.

At swiss water they use water zero chemicals from the coast mountains of british columbia to gently remove the caffeine until the coffee beans are 999 caffeine free while maintaining the beans distinctive origin and flavour characteristics. The swiss water process involves using an ingenious trick to remove only the caffeine while leaving everything else behind. The caffeine rich solution full of flavours is then strained though activated carbon which captures the caffeine.

To begin the decaffeination process green coffee beans are soaked in hot water to dissolve the caffeine. Water with caffeine from the green beans is sent through charcoal which strips out the caffeine if you want to obtain one kilogram of coffee to drink how much water will you need to heat. The swiss water process results in coffee that is 999 caffeine free.

First a batch of green beans is soaked in water. The swiss water decaf process uses water and clever tech to decaffeinate coffee without chemicals. That gce is then passed through specialized charcoal carbon filters which are shaped to only filter caffeine molecules out and reintroduced to a batch of green beans.

It can then be used to decaffeinate any other. And some leave behind more caffeine than you would think. Other methods use chemical solvents including methylene chloride or ethyl acetate to strip caffeine molecules from the green coffee bean.

Then the first batch of green coffee is thrown away and a carbon filter is used to capture the caffeine from the water. However caffeine isnt the only water soluble substance present in coffee. In a nutshell the swiss water process relies on caffeine solubility dissolvability and osmosis to remove caffeine from green coffee beans.

The swiss water process uses a liquid called green coffee extract or gce that is created by removing the caffeine from a batch of green beans and then discarding those beans. The now caffeine saturated green coffee extract is then processed through activated charcoal to remove the caffeine thus becoming caffeine free again and ready to extract caffeine from a new batch of coffee. At this point the water is filled with caffeine and coffee flavor molecules.
