What Is Decaf Coffee?
It is a kind of coffee made from the beans of coffee after the majority amount of caffeine has been removed from it before the roasting and grinding.
How Does Decaf Coffee Taste?
Decaf coffee certainly has a varied taste when compared to regular coffee. Since the caffeine in a regular coffee gives a more bitter taste, the decaf coffee variation will be less bitter and lighter. A few people even find it flavorless.
Does Decaf Coffee include caffeine?
Yes, there is caffeine. Your decaf coffee has approximately 97% of the caffeine removed from it, but the remaining 3 % caffeine is still within your decaf coffee.
How Does Decaf Coffee Compare to Caffeine Coffee?
Decaf coffee makes a better choice if you suffer from acidity, caffeine-addiction, avoid the side effects of caffeine or dislike the bitterness of regular coffee. Both Decaf coffee and regular coffee have pros and cons. It is more of a personal choice.
Does Decaf Coffee Have to Be Dark Roasted?
It is preferred to dark roast the beans for decaf coffee, as it will increase the sweetness of it. A light roast would lack good flavor.
Is Decaffeinated Coffee Considered A Specialty Coffee?
It is possible to have specialty Decaf coffee. This is possible with the Swiss water method of decaffeination, which retains maximum flavors of regular coffee.
How Is the Caffeine Removed from The Coffee Beans?
Soaking the Beans
The unroasted green colored beans are first soaked in water. This step allows caffeine with quite many flavors to come out of the beans. This step is the first common step to all the methods mentioned below to make decaf coffee.
Direct Solvent Method
This is the stage when chemical-based solvents such as ethyl acetate or methylene chloride can be added to the coffee and water mixture. This is done to extract caffeine off the water.
Indirect Solvent Method
In this method, after soaking the beans, removal of water is done, after which the solvent is added.
After using the direct or indirect method, the caffeine plus solvent removal is done from the mixture. This is achieved through the evaporation of the water. Thus, leaving the flavors with the coffee.
The Swiss Water Process/Activated Charcoal Decaffeination
In this method, no chemical solvent is used. The caffeine can be removed from water with a charcoal-based filter. This method works on the process of osmosis and solubility.
The porosity of the charcoal-based filter captures only caffein particles. Oil and flavor particles which are smaller go through to the other side.
Now, we have coffee without caffeine on one side, which will be discarded, and flavored caffeine-free water on the other side. The flavored water is used to extract caffeine from another batch full of beans. With this batch, only caffeine will move to the water as the water is full of flavor.
This results in decaf coffee beans with retention in flavour.
Carbon-Dioxide Method/Supercritical Carbon Dioxide Method
This is the most recent method to make decaf coffee. In this method, liquid carbon-dioxide is used at greater pressure for dissolving caffeine. Then, reducing the pressure, carbon dioxide turns into the gaseous form, leaving the caffeine out. In this method, the carbon-dioxide is reused to repeat the process for the following set of beans.
The Mountain-Water Process
The decaffeination process in this process is similar to the Swiss-water process, but in this method, pure glacier water is incorporated.
Why Is It So Difficult to Make Good Decaf Coffee?
There are two main reasons why good Decaf coffee is difficult to make:
Firstly, during the process of decaffeination, coffee beans tend to lose most of their flavors. It becomes challenging to retain the flavors of coffee people tend to enjoy.
Secondly, decaffeinated coffee beans tend to be brown instead of the usual green. This makes it challenging to roast the beans as they will roast inconsistently, and it won’t be easy to control it. They also are more likely to roast quicker because they do not have much moisture in them.
Is Decaf Coffee Bad for You?
