Decaffeinated Tea

Decaffeinated Tea: an overview

For some, the notion of decaffeinated tea (or indeed, coffee) is quite simply unfathomable. However, decaf tea is quite popular, even among tea drinkers. There are those who want to enjoy tea just for its robust flavor. There are also people who want to be able to drink tea and coffee, but who cannot consume caffeine for one reason or another. For such individuals, decaffeinated tea offers a legitimate means to have one thing, without having to be concerned about the other. You will find that most of the top tea manufacturers in the world offer at least a few decaf options for those who are interested.

If you are curious about decaffeinated tea, there are a number of fascinating aspects to the subject that should be kept in mind. For example, you may be wondering if decaffeinated tea still contains caffeine. You may also be curious about the process by which caffeine is removed from the tea leaves. After all, the presence of caffeine in tea leaves is a natural one. There is no such thing as decaffeinated tea leaves in nature.

All of these questions are worth keeping in mind if you are interested in learning the pros and cons of decaffeinated tea, as well as other aspects.


Another pressing question with decaffeinated tea concerns health benefits. There are a number of different health benefits associated with different teas. This includes the decaf variants. In order to answer these questions, we need to look back to where the idea of decaffeinated tea came from in the first place.

That means going back to the history of decaffeination itself. The story begins in 1820, when Friedlieb Ferdinand Runge became the first to isolate caffeine from coffee beans. He had done so at the request of the poet Goethe. However, Runge had no interest in further exploring the concept, or in exploiting its potential commercial appeal. That would come from Ludwig Roselius and his team, who created the first commercially-viable decaffeination process in 1903. His process was then patented in 1906. There is a story that alleges that Roselius had been compelled to do this because his own father had died from drinking too much coffee.

The original process utilized a brine solution to steam the coffee beans. The chemical known as benzene was then used to remove the caffeine. Benzene is of course no longer used, as it has been long established as a significant human carcinogen. In the present, there are essentially four different ways to extract caffeine, with two solvent-based methods and two non-solvent methods. There is also a popular option known as the Swiss Water Method.

While we do not know the exact date of when this work was carried over to tea leaves, we can guess it was a handful of decades following the popularization of decaf coffee. In the present, CO2 decaffeination is one of the more popular methods of decaffeinating tea leaves. Methylene Chloride, Ethyl Acetate, and water processing are three other methods that can be used to extract the caffeine in tea leaves.


Generally speaking, decaf teas contain the exact same ingredients as their caffeinated counterparts. The only difference is significantly less caffeine.

It can also be helpful to remember that there is, in fact, a difference between decaffeinated tea and caffeine-free tea. With caffeine-free teas, you’re talking about teas that did contain caffeine at any point in the manufacturing process. This means they are completely devoid of this element. With decaffeinated, it is possible for small amounts of caffeine to remain. The amount that remains will depend on the process being used.

Finally, a word on the subject of oxidation. This is a key influence on the amount of caffeine that will be found in the tea leaves themselves. For example, black teas have the most caffeine of all the different types of teas, and this is due to the fact that the leaves are the most oxidized. Oolong teas, green teas, and white teas all have lower oxidation levels. In other words, they have lesser amounts of caffeine than black. Tea, in general, is sometimes used as an alternative to coffees, which tend to have the highest caffeine contents of them all.

Yet for some, the need for decaffeinated tea continues to compel manufacturers to offer different types of decaf tea in stores and online. Let’s take a closer look at some of the benefits that can account for this fact.


While some may not understand the preference of another to drink decaffeinated tea, there are nonetheless a number of benefits to those who do. The main one would come down to the matter of less caffeine. While caffeine can be beneficial to many, providing energy and other health benefits, it can also create issues for others. Such issues can appear in the form of migraines, sleeplessness, increased anxiety and increased irritation/anger. Further issues can arise from these problems.

There is also an addictive component. Caffeine is a stimulant. This fact carries with it the potential for abuse by an individual, which in turn can create some or all of the physical issues mentioned above. There are also physical and psychological withdrawal symptoms that can occur, which can include sleeplessness and serious depression.

While decaffeinated tea still has small amounts of caffeine, the potential for addiction and abuse still goes dramatically down. It is also possible for the individual to still benefit from the small amounts of caffeine, without consuming so much that it leads to headaches or anxiety. Many individuals have a sensitivity to caffeine that makes decaf options an invaluable alternative. There are also personal and religious reasons as to why someone may not be able to consume caffeinated tea. Decaf gives them a viable alternative, as well.

Because of the low caffeine count, you can drink decaffeinated tea at any point during the day. You can drink it in much larger amounts than you would with caffeinated tea. This is a nice benefit to those who genuinely enjoy the taste of tea, and would like to be able to drink it without any serious consequences.

Decaffeinated tea also benefits from being a little more flexible than its caffeinated counterpart. It can be combined with herbal caffeine-free teas to suit your needs at a particular moment. This means you can enjoy an herbal blend as a means of winding down, or you can combine with a Darjeeling or white tea to create a perfect beginning to the day.

The benefits of decaffeinated tea are clear. However, there are some potential downsides that should also be kept in mind.

Side Effects

Are there side effects to decaffeinated tea? Yes and no. It really comes down to how your body responds to things. It can be just as helpful to understand the question of whether or not decaffeinated tea is as healthy as tea containing caffeine. This is where things can get interesting.

If you have an extreme sensitivity to caffeine, it is entirely possible that even in the decaffeinated form, your body will still have what could be described as a negative reaction. This only concerns those with acute sensitivity, but it is something to still keep in mind. For those who cannot tolerate caffeine in any form, a caffeine-free tea might be your best bet.

It is also possible to feel mild diuretic discomfort. This again depends on the individual, as well as such as issues as how often you drink the tea, how much you drink, and how your body responds to the specific ingredients. Most do not need to worry about this, but it is still a good idea to pay attention to how your body responds to things.

Finally, there is the matter of whether decaf tea has the same healthful qualities as caffeinated tea. The short answer is yes, but the longer answer must take into account that decaffeination processes for tea can remove other components, in addition to the caffeine. Some polyphenols and antioxidants, two essential components to the health benefits of tea, can be destroyed in the work involved in decaffeinating tea leaves. This amount obviously varies from one process to the next.

However, there are still health benefits to decaffeinated tea. While things like flavonol content and antioxidant numbers can go down, they do not disappear entirely. The overall content can still be described as useful. An individual could potentially offset the loss by drinking a little more than they would the caffeinated version.


Decaffeinated tea can be prepared and enjoyed in the exact same fashion as caffeinated tea. In other words, bring your water to a boil, add the water to your tea, and allow it to steep for a few minutes. The time can fall anywhere from three to ten minutes, depending on the type and desired strength/flavor.


While decaffeinated tea is clearly not for everyone, there are still some benefits that give it a place of considerable use and importance in the world. It is a worthwhile option for those who cannot, or do not want to, consume caffeine.
