What is Decaf Coffee 

Decaf coffee, also known as decaffeinated coffee, is coffee without the majority of caffeine content. There are different ways in removing caffeine from coffee beans. One famous process of removing caffeine is using a solvent to “wash” the caffeine off the beans. This includes water, carbon dioxide, and organic solvents.

Some coffee drinkers would not notice the taste difference from a decaf coffee variation of their favorite regular coffee. But regular coffee drinkers would not only notice the taste difference, but also the lack of energy from the lack of caffeine.

Origins of Decaf Coffee

The process of decaffeinating coffee started in 1820 which was carried out by Friedlieb Ferdinand Runge. The first to commercialized decaf coffee was created by a German merchant named Ludwig Roselius in 1903. After observing that the coffee beans that were accidentally soaked in seawater still had the coffee flavor to them but without the caffeine content. He then proceeded to have the process patented in 1906. 

Decaffeinating Process

In order to create decaffeinated coffee, different methods and processes must be followed. However, in recent years, local countries are finding new ways of modifying coffee plants to grow coffee beans with already low caffeine content. 

In order to start the process of Decaffeinating, un-roasted coffee beans must be placed into water and left to soak. This allows the caffeine content to be washed off. Then there are three different steps that can be taken:

Liquid Carbon Dioxide

Another process that only uses natural components is Liquid Carbon Dioxide decaffeination. This one uses liquid carbon dioxide to break down the caffeine and remove it from the water and coffee bean mixture. 

Chemical Decaffeination

The first process of decaffeination involves the use of Methylene chloride chemicals. This chemical is also used in ethyl acetate or paint removers. What happens in chemical decaffeination is that the chemical is added to the coffee and water blend. After that, water is then entirely removed using evaporation so that the caffeine content be removed but the flavor is still intact. 

Swiss Water Process

The Swiss Water Process uses a charcoal filter to get rid of the caffeine without the use of any harmful chemicals. This process is simpler and safer compared to chemical decaffeination.

How is Decaf Coffee Different?

By now you already know that decaf coffee is coffee that had its caffeine removed. That is the most obvious comparison between decaf coffee and regular coffee. Let’s take a look at the differences in a bit more detail:

Less Caffeine

Now, most people actually believe decaf coffee to have no caffeine in it, that is untrue. Decaf coffee will always contain traces of caffeine, but the amount is not enough to have any effect on the body as a regular coffee would. 

According to the National Coffee Association – “Decaffeination removes about 97% or more of the caffeine in coffee beans.”

The content of caffeine in decaf coffee is around 2 mg compared to a regular coffee at 95 mg.

As you can see, there is a noticeable difference in caffeine content. If you were to drink 15 cups of decaf coffee in a day, you could feel some of the effects of caffeine, especially if you never consume caffeine.  

More Acidity

It’s common to believe that decaffeinated coffee would not have as much acidity, but this couldn’t be far from the truth. Decaf coffee has higher acidity in every cup due to the type of coffee beans used. It is usually made with Robusta beans, and these beans have higher acidity than Arabica beans.

This isn’t necessarily a good thing either. Higher acidity can lead to a number of health problems including:

  • GERD (Gastro esophageal reflux disease)
  • Acid reflux
  • Osteoporosis
  • Increased Cortisol Levels

This is not to say that these effects will impact everyone, but it is important to point out as why is decaf different.

Health Benefits

When talking about the health benefits of decaf coffee and regular coffee, they should be taken with a pinch of salt. Each type of coffee has different benefits and each benefit can impact a person in different ways. It is also worth noting that both types of coffee also have negative health impacts as well.

The most obvious health benefit of drinking decaf coffee is for those who cannot consume caffeine for health reasons. Whether it is for blood or heart problems, there can be many reasons that people are forbidden to drink caffeine. No one wants to miss out on coffee, so decaf is the answer.

Decaf coffee has a number of properties that studies have shown protect from cancer, are antioxidants, and help to prevent free radicals. These include Ferulic, Caffeic Acid, and Chlorogenic Acid. These properties have demonstrated benefits but again should be taken with a pinch of salt.

Overall, decaf coffee is a good option to replace regular coffee every now and then, just to lower the amount of caffeine. 

People that find it hard sleeping, get anxious, and feel stressed, may find it beneficial to switch to non-caffeinated drinks. 


It can be hard to identify the exact difference in taste, but there is no denying that decaf coffee tastes different to regular coffee. The main difference you will notice is that decaf coffee tastes considerably weaker than regular coffee. That is no surprise when there is no caffeine in there!

To sum this up, regular coffee contains caffeine while decaf coffee lacks caffeine. Decaf coffee provides some health benefits, a different taste, and more acidity.
