If you ever wondered what decaf tea is, you are not alone. Recently, decaf teas have been gaining popularity, and for a good reason. They may provide similar benefits as regular teas, but minus the potential side-effects of caffeine. Read more about deaf teas in our guide.
What is decaffeinated tea?
Caffeine is a hot topic among health-conscious people, and many tea drinkers refrain from drinking tea only because of caffeine. A regular cup of tea will have anywhere between 20 to even 100 mg of caffeine. The amount of caffeine will depend on many factors, and although you can control some of them, you will never be able to fully remove caffeine from tea by yourself. For example, steeping less tea leaves in cooler water for shorter time will give a cup will less caffeine, but weaker a flavor too. Washing tea leaves with hot water before making a cup won’t remove caffeine either.
However, good news is, you don’t need to stop drinking Camellia sinensis tea altogether. Decaf or decaffeinated tea is tea that underwent a process of decaffeination or removing caffeine. There are different methods of removing caffeine from tea leaves, and some may be better than others.
The most common ways of decaffeinating tea are:
1. Using direct solvents
Decaffeination methods using direct solvents such as ethyl acetate or methylene chloride remove not only caffeine, but most of the nutrients and flavor too. Tea leaves are steamed and soaked in solvent until most of the caffeine is removed. This is the oldest decaffeination method that first appeared more than 100 years ago.
2. CO2 method
CO2 or Supercritical Carbon Dioxide method is currently considered the best method for decaffeinating teas. Unlike other methods, it preserves almost all nutrients while removing the caffeine. This means that both health benefits and flavor will stay mostly the same as in the regular tea. Approximately 95% of the nutrients are left intact.[1] Tea leaves are soaked in water or ethanol and placed in high pressure vessels while CO2 acts as a solvent.
Difference between caffeinated and decaf teas
Decaf and caffeinated teas, although very similar, may still have some differences. Most decaf teas will have smaller broken leaves. The flavor of decaf teas will depend on the tea type and the way it was decaffeinated. Some techniques will preserve most of the flavor and benefits, thus offering a cup that’s not much different from the caffeinated tea. Caffeine content will be significantly reduced, but there will still be some caffeine left, usually less than 2 mg per cup, although some types may have more – even 5 mg per cup.
Interestingly, most decaf teas are still black. Decaffeination of green tea, even using the CO2 method, may reduce the amount of EGCg for up to 37.8%[2]. However, this too will depend on the solvent used in the decaffeination process. Studies showed that using water as a solvent will result in more lost catechins, compared to ethanol – which may reduce the catechin content by only 6.2%[3].
You should brew decaf teas in the same way you brew regular teas – using boiling water for black tea, and cooler water for green tea.
Decaffeinated vs caffeine free tea
Decaffeinated tea is all tea that naturally contained caffeine, but it was later removed through a decaffeination process. Caffeine free tea are all teas that are naturally caffeine free. These are mostly herbal teas, such as peppermint, ginger, rooibos or chamomile tea. Decaffeinated teas are made from Camellia sinensis tea that naturally contains caffeine. All caffeine free teas will have 0% caffeine, while decaf teas may contain very small amounts – but usually less than 2 mg per cup.

Many important and popular classical teas are available in decaf style too. They include breakfast blends, strong and malty Assam teas, muscatel and floral Darjeeling teas, Chinese Keemun tea, green Sencha teas, Chinese Mao Feng tea and fragrant Jasmine green tea and even oolong tea.
