Organic Decaf Coffee: Organic Decaf Coffee stands for Organic Decaffeinated Coffee, which means an organic coffee from which caffeine has been removed. Now, this caffeine can be removed by any of the following methods, all of them not necessarily organic.
• Swiss Water Process: This is so far the only organic process for decaffeination of coffee. So, only the coffee decaffeinated this way can be called Organic Decaf Coffee. This process uses a lot of water. This process is basically same as that used for decaffeinating tea, i.e. the green coffee beans (roasted ones will not do) are repeatedly soaked in hot water and made to pass through a carbon filter (made of charcoal which, you can say, is organic). This pulls out the caffeine from the raw beans but does not harm the flavour much, except in the first run, due to the carbon filter. This process is organic as well as it can remove above ninety nine percent of the caffeine from the beans since it is repeated several times.
Note: You can also try decaffeinating the green coffee beans at home with a method close to Swiss Water Method discussed above; by repeatedly soaking the beans in hot water and then throwing the water away. The more you repeat, the more caffeine is removed. But this also robs the beans of their flavour quite considerably.
• Roselius’ Process: This is one of the oldest methods of decaffeinating coffee which involves treating the coffee beans with salt water and benzene. That is why; it cannot be called an Organic Process. Further, treating the beans with salt solution and benzene does great damage to their flavour and taste. The reason is obvious.
• Industrial Process (Direct): This process is extensively used in coffee industries and this can be both organic and inorganic. In this process, the coffee beans are first treated with hot water and then with Methylene Chloride or Ethyl Acetate. Thereafter, the Methylene Chloride or Ethyl Acetate is dried and the coffee beans are again subjected to hot water. If this process involves Methylene Chloride, then the product turned out is invariably inorganic since Methylene Chloride can only be prepared artificially. But if the process involves Ethyl Acetate, then it gives Inorganic Decaf Coffee if the Ethyl Acetate used in it was synthetic (synthesized artificially) and Organic Decaf Coffee if that Ethyl Acetate was obtained from natural sources (it can be).
Note: Check out the above fact carefully if you are buying Organic Decaf Coffee. Do not proceed if you are not sure.
• Industrial Process (Indirect): This process remains basically the same as Industrial Direct Process discussed above, with the difference that in this case the beans are not directly rinsed with Methylene Chloride or Ethyl Acetate. Instead, the beans are removed after being soaked in hot water and the water is then treated with any of these two compounds to remove the caffeine in it. This process too, can churn out Inorganic or Organic Decaf Coffee depending upon the type of Ethyl Acetate used in it.
