This article will serve to answer this often searched question; whether decaf coffee is a diuretic? First, we will provide a brief definition of the term decaf coffee and diuretic. 


What is Decaf-Coffee? 

Decaf coffee is shorter-term and comes from Decaffeinated coffee. With this term, you may catch a glimpse of what it refers to. Decaffeinated coffee is a type of coffee, in which the coffee beans have had at least 97% of caffeine extracted or removed. 

Decaf Coffee is very desirable for those who would go for coffee with less caffeine but still has a unique taste and health benefits similar to regular caffeinated coffee. 

How is Decaf Coffee Made? 

How is Decaf Coffee Made? 

Likewise to other regular coffee, decaf coffee started in the form of green, unroasted beans, in which the beans are warmed and soaked in liquid to extract caffeine. Then, the soaked, decaffeinated coffee beans are dried to their first moisture content. There are three main decaffeinated processes, including: 

Carbon dioxide method: 

Starting with the most expensive process among the three is using the CO2 method. In this process, the green coffee beans are soaked in supercritical CO2, with high pressure and temperature, making the caffeine exit from the beans into the CO2. 

The CO2 is later pumped out through a filter of charcoal, resulting in only decaffeinated beans. Or, it can be pumped into an absorption chamber in which the CO2 is converted back into the form of gas, leaving the caffeine behind. However, since it is costly, the process is mostly used for a large quantity of coffee into lower grade decaf coffee. 

Solvent method: 

In this particular method, there is an additional use of chemical compounds such as either ethyl acetate or methylene chloride. First, the unroasted coffee beans are steamed then mixed with one of the 2 compounds to make them bond together. When it is readily bonded, we steam the beans again to remove the beans from the solvent and caffeine. 

The Swiss water process: 

Ending off with practically the safest and considerate among the three processes is the swiss water, in which most water is used. Firstly, again, the unroasted beans are soaked in warm water, causing the sugars, caffeine, oils, and other compounds to wander in the water. 

Next, the extract undergoes a filter of activated charcoal to separate the caffeine again. And, since the water is filled with sugars, oils, and so on, it is easier to extract almost all the caffeine from the new combination of beans. 

Is Decaf Coffee completely caffeine free ? 

We all must have the same concept as when we think of coffee, caffeine also comes along. Different types of coffee contain different amounts of caffeine. This raises the doubt of whether decaf coffee is completely caffeine-free. 

The answer is no. Decaf coffee still has a certain amount of caffeine content, as it is not possible to extract all caffeine from the coffee beans. Typical decaf coffee beans have 97 percent of caffeine extracted, which means for a regular 8-ounce cup of coffee, there is still approximately 2 to 6 milligrams of caffeine. 

However, the caffeine quantity can also vary depending on some factors, such as the coffee brands, coffee beans, procedures, and so on. Read more on Coffee Truth About How Much Caffeine in Decaf Coffee for deeper details.
