What is decaffeinated tea and how does it taste?


decaffeinated tea

Tea has a delectable taste, a soothing aroma, and the ability to gather together folks as a social drink. But there comes a time when we want to enjoy tea without the energy-boosting caffeine powers that tea so expertly delivers. For some tea lovers, this may sound incredible, but consider individuals who have caffeine sensitivity or want to enjoy some tea before bed. Luckily there is a whole wide range of tea for this demographic of tea lovers, too. Let’s explore more about decaffeinated tea.

What is decaffeinated tea?

Decaffeinated or decaf tea is tea leaves that have undergone one of several different methods that significantly decrease the amount of caffeine present in the final product. Since true teas, which come from the camellia sinensis plant, are naturally imbued with caffeine, it requires some special techniques to get that natural caffeine out! Non-camellia sinensis teas, however, usually do not have any caffeine at all and would fall under the category of non-caffeinated tea. Non-caffeinated tea includes teas like ginger tea, rooibos, chamomile, and mint tea. 

Being decaf does not mean there is absolutely no caffeine leftover in the tea, just a greatly diminished amount. The type of tea leaves can be green, or black or even Oolong, and virtually any variety of camellia sinensis tea leaves can be converted into decaf versions of themselves.

How is tea decaffeinated?

There are four main methods used to get the caffeine out of tea leaves. One of the most popular is through the use of carbon dioxide. Some other techniques include using water and some other means of chemical prestidigitation that renders the once caffeine-packed tea leaves with far less caffeine than before!


The water processing method is generally used to decaffeinate loose leaf tea. This method includes soaking the leaves in water and then straining them with a filter that snags most of the caffeine out. The water is then returned to the leaves to fortify the flavor, but this usually results in a tellingly watery tea taste.

Carbon dioxide

This method is one of the most common, popular, and also effective means of decaffeinating tea. It is also the most natural of the four ways and allows the flavors and health benefits to be maintained even after the caffeine is largely expelled. This process includes using high temperatures and pressure to ratchet up carbon dioxide to a heightened state. When this occurs, carbon dioxide causes a chemical reaction that saps a good portion of caffeine while leaving most of the other flavors and nutrients intact. 

Ethyl Acetate

A chemical method of decaffeination. However, this method can alter the final taste of the leaves. This technique involves soaking the tea leaves in the ethyl acetate solution to get some of the caffeine out. While this method does the trick, the ethyl acetate leaves behind a bitter chemical taste.

Methylene Chloride

By soaking the tea leaves in methylene chloride, the tea leaves can lose a decent chunk of their caffeine but still keep their natural flavors, aromas, and nutrients. The drawback to using this method is that the chemical used, methylene chloride, is also linked to birth defects and the development of cancer. Try to seek out decaf prepared using one of the other three methods.

How much caffeine is in decaf tea?

As we mentioned before, decaf still does have some caffeine. But exactly how much? And how does it stack up against fully caffeinated tea? Decaf tea usually contains 1 to 8 milligrams of caffeine per cup. This is a significant decrease since the average cup of fully caffeinated green tea contains 25 to 50 milligrams of caffeine and black tea? Anywhere from 30 to 60 milligrams per cup. 

What does decaffeinated tea taste like?

Depending on the method of decaffeination used, your tea may taste many different ways. 

The two chemical methods, using methylene chloride and ethyl acetate, usually leave a peculiar bitter chemical flavor. Meanwhile, the water processing method may impart a washed-out taste to your tea. The carbon dioxide method, on the other hand, will leave your tea with pretty much the same flavor as if it was fully caffeinated. 

What kind of decaf teas are currently available?

For those who want to still enjoy their favorite tea long into the night, or who want a less caffeine-boosted spot of tea, have no fear as there are scores of different decaf tea varieties on the market today.
