What is decaffeinated coffee?

In simpler terms decaffeinated coffee is like traditional coffee but with the caffeine compound removed. Technically around 97% of the caffeine is removed through the decaffeinating process. Hence, in decaffeinated coffee there is always a small residual of caffeine but in some cases it may be up to 20%!

Decaffeination was first done by Friedlieb Ferdinand Runge in the 1820. The poet Goethe after remarking Runge’s work on belladonna – a poisonous plant, requested him to analyze coffee beans. Although he was able to isolate caffeine compound from the coffee bean, he was neither eager to learn more about caffeine chemistry nor interested in using this process for producing commercial decaffeinated coffee.

How coffee is decaffeinated?

There are several methods to separate caffeine from coffee beans; by using water and organic solvents or carbon dioxide. The coffee beans are washed in the solvent until the caffeine has been extracted from it, then the solvent is removed.

There are 2 types of solvent method which are the Indirect-Solvent and Direct-solvent process. The direct method is where the coffee beans are washed directly in the solvent. In the indirect method, the coffee beans are first washed in hot water which remove the caffeine, oils and other flavor compounds. The solution obtained is then treated separately by adding the solvents methylene chloride or ethyl acetate. Then it is heated so that the caffeine and solvents are removed through evaporation.

Finally, the coffee beans are boiled again with this mixture that contain only flavor compounds and oils in order to reinstate its taste. In the Swiss Water Process the coffee beans are also boiled in hot water.

However, this time the caffeine is removed from the water through the process of percolation and not by using solvent. Then the beans are reboiled in this water to reabsorb the caffeine-free flavor elements. It is important that the coffee beans are decaffeinated before they are roasted and ground to keep its nutritional value and the taste of ‘regular coffee’.

  1. Interesting article.

    I, personally, loath decaf. I am little bit of a coffee addict. But I’m sure it has its purpose in the world and it was very interesting to finally find out how they make decaf. I’ve been looking for a comprehensive explanation for a while and your infographics deliver that very well.

  2. Hi,
    My coffee drinking is pretty well controlled. I usually have only one small cup a day and only in the morning. During weekdays that is literally a small cup that is half-filled. At weekends I activate the espresso machine and make myself a cappuccino. Though I drink a very small amount of coffee a day I intensely dislike weak coffee and to me, decaf just tastes like weak coffee with a nasty insipid twinge to it. I really like the thick intense shot effect you get from Greek or Turkish coffee. I will very occasionally drink decaffeinated but only if it is the only thing available. So far I am not subject to any of the adverse effects of coffee and caffeine so I don’t feel compelled to try to switch to the decaffeinated version – thankfully. And to be honest I hope I never have to.
    Best regards
    Andy

  3. Hi Arnaud,

    Great Post!

    Interesting and well-detailed article. Truly loved the content of decaffeinated coffee, it acts as an energy booster but due to personal choice decaf coffee is an excellent way to enjoy a cup of coffee without ingesting that extra caffeine.

    Never knew the methods of decaf coffee but your efforts to illustrate it with a diagram is truly commendable.

    Decaf coffee is a healthy option because drinking too much caffeine can result in insomnia, irritability, headaches, nausea, and anxiety according to researches conducted.

    Thanks for sharing!

    Cheers!
