We have all, at one time or another, indulged in a decaf coffee, especially in the evening. This is coffee from which the caffeine has been eliminated, that substance that stimulates our nervous system, waking us up and making us more active.
Decaffeinated coffee was invented at the beginning of the 1900s in Brema, and was soon marketed under the name Hag.
But how is decaffeinated coffee made? Let’s take a look at the various methods!
How decaffeination takes place
There are basically three methods used for obtaining decaffeinated coffee and one that is still being developed:
- Through the use of an organic solvent. The raw beans are placed in water to increase their volume. Then an organic solvent is added that eliminates the caffeine. When the coffee is toasted, the residue of this solvent evaporates, making the beans 100% safe;
- With water. The raw beans are immersed in cold water that is filtered through activated carbon. However this method also eliminates a portion of the coffee’s organoleptic qualities;
- Through the use of carbon dioxide. In this case the beans are treated with vapour and then put in special cylinders where carbon dioxide is inserted at a controlled temperature and pressure. This method selectively eliminates the caffeine with no consequences from an organoleptic standpoint;
- Through genetic engineering. Recent research has made it possible to identify the gene that produces caffeine. Therefore it will soon be possible to create a decaffeinated coffee plant that grows decaffeinated beans right from the beginning, thus making it all-natural.
Some interesting facts
- Contrary to popular belief, decaffeinated coffee is not bad for you. Any potential substances (residue of the decaffeination process) are completely eliminated during the toasting phase;
- The method which uses organic solvents is hardly every used any more these days;
- Regardless, decaffeinated coffee contains a small portion of caffeine (approximately 0.1%);
- Italy is one of the leading countries in this field.
Now that you know all there is to know about decaffeinated coffee and how it’s made, you simply have to try it! Taste our blend, decaffeinated using the natural method: an excellent coffee, but without caffeine.
